There's definitely more videogame characters than anime but:
- just about any Splatoon character especially Pearl and Marina from 2 and Frye from 3
- most characters from the Sonic the Hedgehog franchise
- Daisy, Rosalina Bowser and Luigi from the Mario franchise
- a lot of the characters from Breath of the Wild in the Zelda series
- a handful of folks from Supergiant's Hades
- Team Rocket (specifically reffering to Jessie, James and Meowth) from the Pokemon series and especially Team Skull or Raihan
and if i had to name any other anime characters it'd probably be anybody from the cast of either Lucky Star, The Melancholy of Haruhi Suzumiya, Mekakucity Actors, Free! or Madoka Magica
there's also Hatsune Miku (and other vocal synths) but it's hard to know if she's considered a music exclusive identity or one who can be associated with games or even anime with the number of titles that have come out over the years as well as show cameos
