Anime: Heiji Hattori from Detective Conan & Haruhi Fujioka from Ouran High School Host Club Cartoon: WALL-E from WALL-E & Katie "Pidge Gunderson" Holt (Although I LOVED Héctor from Coco ) Game: Silver the Hedgehog from Sonic series & Princess Zelda from Legend of Zelda (Breath of the Wild in particular)
Of course I like WAY more, but these are my current favourites
My favorite male and female characters from an anime/game/cartoon/etc. would include the following I can think of:
Sonic The Hedgehog and Amy Rose from "Sonic X" Nick Wilde and Judy Hopps from "Zootopia" Fox McCloud and Krystal from "Star Fox" Bernard and Bianca from "The Rescuers Down Under" Ash and Misty from "Pokémon" Danny and Sawyer from "Cats Don't Dance"
As always, I cannot name anyone particular, but this time it's not because I have so many that I cannot choose, but because I cannot find anyone to nominate. Most of my favorite characters are fan-made, so I'm not sure if I can nominate them (can I?). Not to mention that I seem to adopt my best friend's "prejudice" against human characters (unless they come from live action movies or games that are supposed to look realistic). The only more-or-less official character that I'm really fond of is already in your gallery. I really can't think of anyone else without of going into "fan-made" territory.
