Pokemon

PIKACHU

Male - Electric - Static
Thunderbolt - Electro Ball - Quick Attack - Iron Tail

Pikachu was Ash's first Pokemon and his best friend. Having been together for so long Pikachu is much like his trainer and they are rarely one without the other. If there is ever a time that one is without the other you can bet that their first priority is finding one another again. Packed with speed and electricity Pikachu is a reliable asset in battle as well.

SNIVY

Female - Grass - Overgrow
Vine Whip - Leaf Blade - Leaf Storm - Attract

Sassy Pokemon who normally keeps to herself and doesn't show too much emotion outside of battle (with some exceptions). But just like all of Ash's Pokemon she is loyal to him as while Snivy left her old trainer she found what she was looking for in Ash. Snivy is also kind of the sister figure in Ash's Pokemon group as she watched over all of Ash's other Pokemon (like Pignite).

CHARIZARD

Male - Fire / Flying - Blaze
Flamethrower - Dragon Tail - Wing Attack - Slash

Charizard is one of Ash's long-time Pokemon companions. They've had a bumpy road but since then they have grown a pretty tight bond. Doesn't stop Charizard using Flamethrower on Ash still (but at least it's out of love now!) but if Ash needs Charizards help the Pokemon is very willing to give.
