I have many favorite characters. One of would which would be Gwen Stacy when she was Spiderwoman or as the general populace knows her as Spider-Gwen. Idk why they decided to use that nickname.
As for favorite movies. I have alot of animated movies I like that are far numerous than the live action ones but I'll use live action this time and keep up with the marvel theme and say Guardians of the Galaxy 2
Danny Fenton/Phantom (Danny Phantom)
XJ-9 (My Life As A Teenage Robot)
Umbreon (Pokémon)
Alain (Pokémon)
Greninja (Pokémon)
Sceptile (Pokémon)
Charizard (Pokémon)
Etc.
There are quite a few Characters that I consider my favorites. One of them is Junko Enoshima from Danganronpa. The same applies for Movies. One example is Kung Fu Panda (I especially loved the 2nd one) !!!!
