I'd love to see a Champion who is cursed, but uses said curse for good deeds
While you might say "Kai'sa", she's not exactly what I have in mind; she took on that Void symbiote just to survive, not specifically to do good deeds. I'm thinking more along the lines of a Dark/Black Knight archetype, with examples like Cecil Harvey (Final Fantasy 4), Genn Greymane (Warcraft), or Ragna the Bloodedge (Blazblue). Presently, there aren't any Champions who totally fit that.
Imagine having a Dark Knight Champion from Demacia, someone who willingly takes on a dark power in order to protect the country, even though taking on said power damns them. I'd love to see that at some point.


rework :)
....well, before his relaunch.
ever gets his full backstory revealed and/or moves forward in the current lore, he could definitely become this.
