There are three sections total in the Super Meter bar. A single bar can be used to enhance special moves and sometimes combos for characters who are capable of performing it. Two bars will allow the player to perform a Breaker. Having the bar completely filled would grant the player the option of performing an X-Ray.
At the start of the match, both players start with a single bar of their Super Meter filled, allowing each player to perform one enhanced attack. Either player who successfully lands the first hit of the round will be granted another bar of their Super Meter, which would be enough to perform a Breaker.
The super meter is increased by either taking damage, recovering from attacks, wake-up attacks, having attacks blocked or when during a (MK9) Tag Battle, performing Fast Tags.
- The Super Meter shares a familiar role to the EX Gauge in Street Fighter IV, which functions similarly by using portions of the bar to either enhance a special move, cancel out of a special move, or use a Super Attack, which, like the X-Ray, must have the bar completely filled up but is capable of causing a very high damage output if the attack is successfully landed.
