So hard to pick a character when there are so many to choose from....

Heroes I've considered:
[s]Ghost Rider (Alejandra Jones)[/s], some version of Spider-Girl/Woman, some version of Wonder Girl, Jesse Chambers (Jesse Quick/Liberty Belle), X-23, Psylocke, Vixen, Husk, Miss Martian, Spoiler, and Karma.

Villains I've considered:
Menace, Fury the Goblin Queen, Ursa, Faora-Ul, the Beetle (Janice Lincoln), and Killer Frost.

Some of the above characters I've considered changing their alignments.
