Some of my other main character in the works has powers slightly similar to fury, in that his soul is kind of loose in his body (thanks to taking a certain attack) so can flow out looking like energy (or how anime views energy) and it can flow out around him sort of like a shield. However, there's a ton of differences as well and he's lower tier.

In theory, fighting all of my characters (minus my too powerful ones) would be horrible for fury in that they can exploit his weakness of wearing him down unless you say they are all in the area at once and he just uses his strongest form from the start to smash them all before his shields go down.
