The Netsu Power is the temporary state your character is in when the lifebar outline is flashing red. It is also known as the Anger Power, because it activates when your on screen character gets hit a set number of times and the off screen characters gets angry. The number of hits required for the Netsu activation depends on which characters you have teamed up.

During the Netsu Power your character will inflict 1.3 times the assigned standard damage. Unlike popular believes the Netsu extra damage cannot be accumulated with the Ki Power damage, the Ki Power damage modifier will take precedence over the Netsu Power in this case. If you start a throw but the Netsu runs out before the actual throw damage registers it will do the normal amount of damage.

Below is a list of the number of hits it requires for the Netsu Power Up to start. It does not matter what kind of hit it is, mid air juggle hits, unblockables, special moves or a plain and simple jab all count as a hit. A zero in this list indicates there is no Netsu activated when the character is off screen. A throw is counted as 1.8 hits.
