the idea of an unlockable character could be interesting - maybe you could have a small story for that character that is tailored for a solo adventure? even just a short one.. the story could be inside a dream world or some sort of abstract / surreal "mix up" world made due to multiverse being messed up and the unlockable character collects 12 or so special items to fix their world or similar.. the unlockable character could also have their own villain for their story which is once again tailored for a single player fight.

just a few suggestions.
