Ivysaur is my second favorite sophomore (second evo) of all the starters. He's spunky and talented, like a young Brando. Charmeleon is a bit of an egomaniac, and Wartortle gains these weird fluffy ears and tail and then just loses them in Blastoise. I mean, besides the ears and tail, he's the same as Squirtle. The Bulbasaur evolution line has this great aesthetic look to them; as they get larger, the bulb on their backs slowly flower, which understandably makes them more powerful. This is why Ivysaur rocks hard.
