Z Assists (almost always simply called just simply 'an assist') is a universal mechanic available to all combatants in Dragon Ball FighterZ. Every character has a move that be called upon whilst they are on the sidelines. It has been shown that in Season 3, every character will have three moves to choose from before the battle begins. The characters can be called by pressing either the 
or 
buttons, with the former calling upon the character set second on the team and the latter calling
the third character. Holding said buttons will instead perform a Z-Change to said character. Calling an assist causes a character to appear, perform their assist move, and disappear.
Every character has three assists that can be selected before a match. A and B type assists are both unique but overall normal assists. The C type assists are much more powerful, but the recharge time is much longer. Furthermore, keep in mind that your assists will not recharge if you have kept the opponent in blockstun for a long amount of time. They will start to recharge a short while after the opponent is no longer being pressured.
Every assist has an incredibly important role on a team. They are used to keep pressure on an opponent, to fill in holes in a character's blockstrings, and to allow combos to be extended to incredible lengths. Upon calling an assist, there is a short amount of time, which varies depending on the character, before the move will be performed. Be wary. It is possible for an opponent to hit said assisting character, and cause them to disappear without performing the assist move. Or, even worse, they might be stuck in a combo with the character currently fighting. In extreme circumstances, they can even be knocked out. Assists take more damage as assists than they would up front.
