Charmeleon - Interestingly, fire-type Pok�mon like Charmeleon have a distinct advantage against ice-type Pok�mon,but not against water-type Pok�mon.
Charizard - When Charmeleon reaches level 36, it evolves into the majestic Charizard.Starting the game with these fire-type Pok�mon can be difficult, but the effort can pay off.

Blastoise - Blastoise's tough shell conceals twin high-pressure water cannons that can pump out hundreds ofgallons per minute.
Caterpie - Once it reaches level 7, it will evolve to the nearly immobile Metapod. If you don't want a Pok�mon to evolve,simply press B before the change is complete to reverse the process.
Metapod - Like Kakuna, Metapod is a kind of transitional Pok�mon, and it won't stay in this form for long. Once it reaches level 10, it will evolve into Butterfree.
Butterfree - Butterfree's flying abilities make it more versatile, than some of the other Pok�mon you'll findearly in your adventure.
Weedle - Weedle has only two attacks, but its sting is poisonous and its String Shot attackcan reduce an enemy's speed temporarily.
Kakuna - Kakuna is nearly incapable of moving and, therefore, it has no attack abilities whatsoever. Its only defense is the ability to harden its protective shell.

Arbok - At level 27, you can add a paralyzing Glare to Arbok's arsenal. At level 36, you can replace Leer with a Defense-lowering Screech.
Pikachu - These mouse-like creatures are among the most sought-after Pok�mon. Trainers never keep many of them in the same place, however. If enough of these Pok�mon gather in the same place, their combined voltage can trigger electrical disturbances in the surrounding atmosphere!
Raichu - Raichu is more powerful than Pikachu. It has such great electrical potential, it must use its tail as a ground to avoid shocking itself!
Sandshrew - You must trade for either a Sandshrew or an Ekans, depending on which version of the game you have. There are no Ekans in the Blue version and no Sandshrew in the Red version.
Sandslash - When threatened, Sandslash curls up into a little ball. It then rolls along the ground to attack or escape.

Clefable - Once a Clefairy evolves into a Clefable, it won't be able to learn any more attacks, at least on its own. You may be able to teach it a new ability with a TM or an HM.
Vulpix - Vulpix is tough to find in the Blue version of the game, and it can't be found at all in the Red version.
Ninetales - As with many Pok�mon, Ninetales can't be found in the wild at all. To obtain one, you must nurture a Vulpix until it evolves.
Jigglypuff - Jigglypuff's Sing attack will send even the toughest Pok�mon to dreamland, leavin it open for a pounding. Looks can be deceiving, and just because a Pok�mon is cute and cuddly doesn't mean it's a cream puff.
Wigglytuff - Wigglytuff's body is soft and rubbery, like a balloon. When angered, it inflates itself to an enormous size to scare off enemies.
Zubat - Zubat has no eyes, and it uses a sophisticated radar system to navigate in the total darkness beneath Mt. Moon. Its Leech Life attack will drain an opponent's energy and replenish its own.

Vileplume - Gloom and Vileplume don't need to move to attack, so Paralyzing them doesn't affect their ability to fight.
Paras - The dual Bug-Grass classification of these Pok�mon is readily apparent in their appearance: Paras attack opponents with bug-like claws for frontal assaults and mushroom-like pods that shoot clouds of Stun Spores, which paralyze almost any opponent. With enough battle experience, Paras evolve into Parasect.
Parasect - Parasect is actually an odd pairing of creatures: a mushroom-like parasite and a bug-like host. Parasect prefers its environment damp and dark.
Venonat - Venonat makes its home in tree branches and its attracted to bright lights, especially at night.
Venomoth - Venomoth is short on physical ability, but long on various disabling attacks. You'd better have lots of Antidote and other cures.
Diglett - The challenge with Diglett is not finding one but capturing it before it faints or runs away � so make sure to keep a lower-level Pok�mon with you as you head into Diglett's Cave. Another interesting trait: Diglett don't evolve, but they do band together in groups of three.
Dugtrio - Dugtrio is actually a group of Digletts that have banded together. This bonding increases their strength by several times, allowing them to tunnel deeply enough to cause earthquakes.
Meowth - If you have a Blue version of the game, look in the fields around Route 5 or 6 to find a Meowth. If you have a Red version, you must trade for one.
Persian - Persian is as clever as it is powerful, using its Growl to reduce an opponent's attack power before striking with its teeth and claws.
Psyduck - A Psyduck defeats its opponents by mesmerizing them with a piercing stare and unleashing a barrage of pent-up mental energy. These Water Pok�mon are rare and are found in both the Red and Blue versions of the game.

Poliwag - Lacking arms, Poliwag sport newly grown legs and live in the water around Viridian City. To capture a Poliwag, trainers must use a rod and go fishing. Over time, Poliwag evolve into the more powerful Poliwhirl and Poliwrath.
Poliwhirl - Unlike Poliwag, Poliwhirl is fully amphibious. It uses various mental techniques to increase the power of its special attacks.
Poliwrath - When Poliwhirl evolves into Poliwrath, it gains Fighting-type characteristics. Abra - Abra lack attack abilities, but their power to teleport their way out of trouble makes them difficult to capture. They will evolve into Kadabra at level 16.
Kadabra - Kadabra relies on a strong mind rather than a powerful body to win. It can send out waves of mental energy that cause headaches at close range.

Machamp - Machoke must be traded to another Game Pak to transform it into Machamp. It gains an extra pair of arms in the process.
Bellsprout - Bellsprout often begins a battle with Growth, which will increase the power of its special attacks. It would be wise to use your most powerful attack before Bellsprout has a chance to launch an attack of its own.

Victreebel - Not only can Victreebel's Wrap attack hold an opponent immobile, it can score several hits in a row.
Tentacool - Tentacool like to float in the warm, shallow waters around Pallet Town, Viridian City, and routes 12, 13, 17, and 18. Inattentive trainers often fall victim to their acidic sting, and Tentacool will evolve into Tentacruel at level 30.
Tentacruel - At level 30, Tentacool evolves into Tentacruel, growing over a dozen new, stinger-tipped tentacles in the process.
Geodue - Commonly found in fields and rocky areas, Geodude usually don't move unless they're disturbed, and they're often mistaken for a rock or boulder. At level 25, Geodude evolve into Graveler.
Graveler - At level 25, a Geodude evolves into a Graveler. As it changes, it's rocky skin develops several layers of jagged scales. These scales are chipped off in battle but are quickly replaced.
Golem - Golem tend to be much larger than Geodudes and Gravelers, so they stand out more in their surroundings. They are slow to anger but are fierce fighters when roused.

Slowpoke - Everything about Slowpoke is, well, slow. Slowpoke tend to take about five seconds before responding to any sort of sensory input, including pain. These Pok�mon are also extremely rare, but they're found in both versions of the game.

Magneton - This machine-like Pok�mon is made up of three Magnemites bonded together. They are known to become more aggressive during sunspot activity.
Farfetch'd - It looks like a duck and quacks like a duck, but it surely isn't a duck! Farfetch'd uses twigs as mini-swords.
Doduo - Though these Pok�mon exhibit Flying-type characteristics, they cannot fly. However, they can run at high speed. Doduo evolve into Dodrio at level 31.
Dodrio - If two heads are better than one, then what about Dodrio's three? When Dodrio rests, two of the heads sleep while the third keeps watch.
Seel - An Arctic-dwelling type of Pok�mon, Seel fight antagonists with their Aurora Beams, which cause damage by decreasing an opponent's power. At level 34, Seel evolve into Dewgong.
Dewgong - Use Dewgong's Rest ability with caution. If Dewgong does recover 100% of its HP with this ability, it will then skip two turns.

Cloyster - Cloyster treats combat more seriously than Shellder, using its Spike cannon attack to hit its target up to five times in a row.
Gastly - No Pok�mon have an advantage over these ghost-like Pok�mon, making them valuable assets to a Pok�mon collection. Over time, Gastly evolve into Haunter and Gengar.
Haunter - Haunter's Dream Eater attack does double duty, putting an opponent to sleep while simultaneously draining its energy.
Gengar - Both Gastly and Haunter can be found and captured in the wild, but Gengar can be obtained only by training a Haunter until it evolves.
Onix - Over time, Onix's faceted skin becomes as black as coal but as hard as a diamond. It is certainly an imposing sight in battle!
Drowzee - Though these Pok�mon have a weak physical attack, Drowzee will use their psychic abilities to make other Pok�mon fall asleep during combat. At level 26, they evolve into Hypno.
Hypno - Hypno survives by putting its prey to sleep and consuming their dreams. It can get sick from absorbing bad dreams.
Krabby - Krabby can be found sidling along in nearly every stream, river, and pond, using their claws for balance and protection. At level 28, Krabby evolve into Kingler.
Kingler - Though Kingler can sometimes be found in inland waterways, it much prefers the open ocean. Its powerful claws can crush solid steel.
Voltorb - Voltorb use a Screech attack to lower their opponents' defense rating before launching an electrical assault. If the odds are against a Voltorb, it may self-destruct to avoid capture. These Pok�mon evolve into Electrode.
Electrode - If you can't find an Electrode in the Unknown Dungeon, look inside the Power Plant or on Cinnabar Island.
Exeggcute - These egg-like Pok�mon travel in swarms, quickly surrounding and engulfing any intruders in their territory. Trainers should use the Leaf Stone to transform Exeggcute into two-legged Exeggutor.

Likitung - Though comical in appearance, Lickitung can be quite formidable. Beware of its Wrap and Supersonic attacks!
Koffing - Koffing store poison gases within their bodies, sometimes causing them to explode without warning. At level 35, these Pok�mon evolve into Weezing.

Rhyhorn - Rhyhorn's bones are one thousand times denser than a human's, giving it incredible physical power and endurance.
Rhydon - Rhydon lives far underground where temperatures reach well over 2,000 degrees. Its rock-like hide protects it from the extreme heat and pressure.
Chansey - This rare and elusive Pok�mon is sought not for its battle skills but for its legendary ability to bring happiness to its trainer.
Tangela - Looking for the world like a walking plate of spaghetti or a two-legged, tail-less sheepdog, Tangela is one of the shyest Pok�mon.
Kangaskhan - Using its stomach pouch, Kangaskhan carries its young everywhere, even into battle. This makes combat more dangerous, not less.
Horsea - The gentle Horsea are better at defense than offense, but unfortunately they can't take much punishment. Trainers should look for Horsea in the waters around Cinnabar Island, Seafoam Island, and routes 19, 20, and 21. Over time, Horsea will evolve into Seadra.
Seadra - At level 32, Horsea's feathery water wings become Seadra's spiked fins, capable of piercing almost any opponent's skin.
Goldeen - Their billowing fins and tails make Goldeen look like they're wearing ball gowns, which is why a Goldeen sometimes goes by the nickname The Water Queen. Goldeen can be found in several bodies of water.
Seaking - Seaking's skill with its horn increases over time. It learns Horn Attack at level 24, then Horn Drill at level 48.

Starmie - Use the Water Stone to transform Staryu into Starmie. Starmie exchanges mobility for size, relying more on its faceted skin for protection.
Mr. Mime - Some Pok�mon, like Mr. Mime, do not evolve no matter how much experience they gather. Mr. Mime's psychic powers, however, do grow stronger over time.
Scyther - This frightening Pok�mon seems to have just as much in common with dinosaurs as with bugs. The razor edges on its wings make its Slash attack that much more damaging.
Jynx - Jynx has an unusual combination of Ice and Psychic characteristics. Its evolution is not known at this time, though its powers do grow stronger over time.
Electabuzz - Like most Pok�mon of its type, Electabuzz is drawn to strong sources of electricity, and the Power Plant is the only place you can find one.
Magmar - Magmar's skin glows steadily with a bright, orange fire.
Pinsir - Pinsir relies solely on its great strength and powerful pincers to overwhelm its foes.

Eevee - Eevee don't evolve on their own, but trainers can use special stones to transform Eevee into three different kinds of Pok�mon. The Water Stone changes Eevee into Vaporeon, a Water-type Pok�mon; the Thunder Stone converts Eevee into the Electric-type Jolteon; and the Fire Stone transforms Eevee into Flareon.
Vaporeon - The Water Stone changes Eevee into Vaporeon, a Water-type Pok�mon. The Leaf Stone and Moon Stone don't affect it.
Jolteon - The Thunder Stone transforms Eevee into the hair-raising Pok�mon called Jolteon. Another Electric-type Pok�mon would come in handy.
Flareon - Use the Fire Stone to change Eevee into Flareon. This Pok�mon's Fire-type powers are a force to be reckoned with.
Porygon - Porygon's crystalline body is unusual, even as Pok�mon go. Some collectors like Porygon as a showpiece and not as a fighting specimen.
Omanyte - This Pok�mon must be cloned from the Helix Fossil by the Pok�mon Lab.
Omastar - Scientists as yet have little data about this resurrected Pok�mon.
Kabuto - Seen from above, this cunning, beetle-like Pok�mon is often mistaken for a smooth river rock.

Moltres - Moltres appears so rarely, most people think it's only a myth. If spotted, it disappears in a flash of fire.
Dratini - Dratini takes much longer than most Pok�mon to evolve. It must reach level 30 before it changes into Dragonair.
Dragonair - Most of Dragonair's abilities, like Wrap, Agility, Slam and Dragon Rage take advantage of its long sinewy body.
Dragonite - It's likely that many fairy-tale dragons were inspired by this winged beast's ancient kin.
Mewtwo - Mewtwo was created in the Pok�mon Lab on Cinnabar Island. Scientists tried to create the perfect fighting machine, and they succeeded - perhaps too well. Mewtwo is extremely hostile and can't stand being in a Pok� Ball.
Mew - Still thought to be mere rumor in many parts of the world, Mew has only been seen in captivity a few times. The most amazing aspect of this ultra-rare Pok�mon is that it possesses the ability to learn every single TM an HM ever created. As a result, Mew is extremely sought after by collectors.
