After seeing her in action in Arcane, I'd love to see Sevika become a champion

While she wasn't exactly one of the more important characters in the show, she was definitely a standout among the characters that aren't in the game already (that aren't dead or being turned into a chinera, of course). She has a really cool design with her mechanical arm, and even has her own little character arc/progression.

If the last episode is anything to go by too, she'll probably play quite a big role in the second season. I'd say there's definitely enough to her to create into a playable character.

Unless she gets killed off on season 2, in which case never mind.
