Well I came up with this concept a while ago,
summary of Fusio Link
After finding the pieces to an cabinet gem,Link is able to transform into a Twilit like being, however his appearance permanently changes in this form if he passes through the Gate to the Twilit Realm(as seen in the image). The infused gem in his body is powered the the magic meter(resource meter) and the Sol meter. If both are at an all time low, he turns back after taking damage, and reverts to his normal form, however, if you turn back while you are in mutated ares(by the gate) you will lose hearts quickly or worse, TNE. Also this form prevents him from being obliterated by Macellrius, without one hit can kill instantly.
Now I am trying to think of things he can do but all I can think of is that he can levitate and have an extend beam sword.
Anyone got any ideas for an empowered Half Twilt half human?
*I cannot find my original full body spr of him, this is what I have in lttp sprite form*
