Ben as Wildvine
In the original series, Wildvine had five vine-like legs, four long fingers on his hands and flytrap-shaped flaps covering his head. He had blue colored bulbs on his shoulders. He had pods on his back that can either be used as explosives or smoke bombs. He had one blue eye in the middle of his face. He wore the Omnitrix symbol on his chest and spoke in an aged, gravelly voice.In Ultimate Alien, Wildvine looked more like the Florauna from Secret of the Omnitrix. Wildvine was brownish-green in color, the bulbs on his shoulders were green, his eye was green and his flytrap teeth were black. He wore the Ultimatrixsymbol on his chest.
In Omniverse, Wildvine regains the color of his ten year old self. He now has only four legs instead of five, and his fingers are much shorter and thicker. Wildvine no longer has the bulbs on his shoulders, instead having patches of light green color similar to those on his hands. He also now has a blue tongue, his teeth are more neat and his chin is bigger. His flytrap teeth are bigger but the same color as his 10-year-old self. Wildvine wears the Omnitrix symbol on a green and white belt. He speaks with a higher voice.
11 year old Ben as Wildvine in Omniverse looks the same as the 16 year old one but wears the Omnitrix symbol on his chest.
