Yeah, in the campaign, Bryan tried using his air power to fly, and ended up collapsing on the ground, then gasped for air after running for 5 min. He exploded a lettuce trying to practice his earth powers cause his air powers didn't agree with it and he went unconscious doing a finishing move in a battle- Kiri had to give him a breath so he could wake up XD poor Bryan is very frustrated at being fragile. He could've become very powerful before this scar T.T
Yeah- he puts a lot of burden on himself to do that thing at the same capability he did before the incident too. He knows what his potential was and now isn't. It's a hard reality for him to accept
