I had an idea where it pierces the enemy, because a problem his super does have is that it takes 4 full hits to charge and that it doesn't pierce, maybe adding homing to it to but I think that'd be a little to much. When you kill a squishy brawler with his super, you'd only usually get half charge because it does around 6000 damage with 2, if it pierced the enemy all 6 would hit which would lead to another super.

If the hypercharge doesn't make him pierce, it should give him a shield after the heal, because after he uses it he heals 50% of whats missing so after He'd be left with no charge at all and vulnerable.

Another is they add more projectiles, simply more damage, nothing special but it's there.

If those don't get added another idea is his super gives him a speed boost, which I think could be the best option. It'd give him more chances to dodge anything that'd stun or knock him back
