What animal? Well, while i'm the 4th one to agree with Kasai, just for the sake of comming up with something original, I think maybe i'm best represented as a Dolphin.
Dolphins are playful and friendly creatures, that get along well with everyone and everything. They are curious about new things, but learn lessons quickly. They enjoy the company of others, which is also the source of their strength. So yeah, that's probably the best answer I could give.
