Might be a thread already. Oh well. Don't feel like checking. XD
I don't have too many proper ideas and I'm awful at typing people. Well unless they're a few "particular" types.
Edit: on second thought it'll grab me some more responses if I do list some characters I think are ENFPs, myself. Mmk.
Hetalia - America, Italy.
Black Butler - kuroshitsuji - that one blonde kid on staff. Not the older military (Australian??) guy. The other kid.
Naruto - First (note that I literally mean 'first') Hokage? No idea. Oh and Naruto's mom maybe.
