I read somewhere that pokemon's names are combinations of Two Words.

So I'm gonna Try and Make a List of all the pokemon's name Combos. You may help if you like.

Bulbasaur= Bulb + Dinosaur
Ivysaur= Ivy + Dinosaur
Venusaur= Venus (I'm guessing as in the Venus Fly-Trap) + Dinosaur

Charizard= Charred + Lizard
Squirtle= Squirt + Turtle
Warturtle= War + Turtle
Blastiose= Blast + Turtoise
Caterpie= Caterpillar + Free
Metapod= Metal + Pod
Butterfree= Butterfly + Free
