Ryu and Simon have a lot of problems while fighting against Bowser because they are melee attackers but in Castlevania and Ninja Gaiden, a lot of long-ranged enemies are harder than Bowser and Simon and Ryu still can kill them without getting hit. Why? Because they can destroy their projectiles. It will solve the problems while fighting Hammer Bros, too. So how about putting that ability into SMBC? I have seen a Health Bar Discussion but Health Bar will make some characters too strong (Megaman, Bass,...) so this idea is more suitable for SMBC.
