Dark Shadow

Dark Shadow is a Quirk used by Fumikage Tokoyami.

Description
This Quirk allows Fumikage to host a shadow-like monster within his body. He can freely contract and expand it out of his body. It appears that the shadow-like monster is sentient as it has been seen obeying Fumikage's commands.

The shadow-like monster's power and personality is affected by darkness and sunlight; In darkness, the shadow-like monster becomes much stronger but it becomes unrulier and therefore harder to control. In sunlight, the shadow-like monster becomes docile and easier to control but its power becomes weaker.
