An AU where Izuku is the child of Kurogiri and Compresses.

Izuku's Quirk: Marbled Mist - The user can create a cloud-like mist. When entities pass through, the user can sense and decide to activate  one of two secondary effects; those being Warp and Capture.

Downside: Theuser is prone to nose bleeds, headaches, and dehydration.

Overuse: 'Marble Lock' (the user doesn't have enough energy or mental capacity to free any captured targets - ie. Exhaustion, fatigue, in certain cases minor paralysis centered on the hands and fingers), 'Warp Fatigue' (The user becomes extremely nauseous, dizzy, and dehydrated, because of this they are unable to create anymore portals)

Notes: Targets are freed from capture by the user snapping thier fingers to release the effect, or the marbles can pass through one of the user's warps (without being held by another person) and the effect will be nullified.

------------

My brain is in the mood to come up with quirks tonight, but not fully fledged ideas :(

Feel free to leave some ideas/suggestions.

I'll come back to this AU later (at some point) to flesh it out more either way.
