Bellossom hands down. I used to not really give this Pokemon much thought until I used it on Silver. It was awesome. Then I used it on Soul Silver. It was awesome then as well. Now it's one of my top three favorite Pokemon of all time. And that's saying something because I have a lot of Pokemon I like to consider favorites of mine haha.
Overall I love Grass Pokemon but I'm just going to make it easy on myself and pick the small cute petal dancer (and the rest of its evolutionary line!). ♥
