Combo Triggers

Certain Combinations of characters have the ability to combine their "Anger Attack". When the Anger bar for each character involved is filled, a bubble with lightning connecting them will appear. They will perform a special attack that is much more powerful then either of their abilities are solo. However there aren't that many combinations at the moment. Below lists the current Trigger character combinations.
 * Berry and Byakuya
 * Straw Hat and Firefist
 * Kaguya and Snake
 * Nana and Empress
 * Hunter and Black Feet
 * Wukong and Veggie
 * Lee and Sand
 * Vortex and Avenger
 * (Avenger and Kaguya and Vortex) this is the wording displayed in the game for Avenger. I have not verified if this is a typo or if it actually requires all three characters.
