I don't have a particular Pokemon I dislike. Instead I like Venusaur the least. Ivysaur looks based as fuck, but Venusaur looks like an old, beaten, low energy of Ivysaur, and I feel that potential could have been spent way better. I dislike Decidueye for exactly the same reason, it looks too jaded and inexpressive.
I like grass starters in general when they look like they're brimming with energy, like all the other starters.
