Combat allows the player to fight NPCs or other players. Its system of combat consists of punches and kicks.
Basic Combat
Basic combat refers to the punches and kicks that are performed by left-clicking and right-clicking or pressing Q and E (or pressing X on the controller, depending on the player's device).
Combos
A combo is a sequence of punches and kicks that are executed when left-clicking and right-clicking (or pressing Q and E or X and Y, depending on the platform). Carrying out the commands in a certain order will execute a special move.
The Basic Combo Set is the basic and primary set of combos. They are chargeable, and can end a combo. The Supplementary Combo Set is the secondary set of combos that follow up the Basic Combo Set. An Assault Chase is performed that is used after a Supplementary Combo Set. There are various Assault Chases that can be performed depending on the set of commands carried out.
Blocking
Blocking is when the player character raises their arms to block any incoming attacks. It's done so by holding down R (or the Right Bumper, depending on the device). In this state, the player is completely immune to any attacks, except for certain skills and heavy hits; however, blocking can also drain the Defense bar.
Perfect blocking is when the player blocks right before their opponent is about to hit them. Upon being perfect-blocked, the opponent will be stunned for a fair amount of time, allowing the player in question to do a counterattack.
Deflecting
Deflecting is when the player blocks and then presses A or D (or, depending on the device, shifts the Left Analog Stick left or right), prompting the player character to swat their arm to the side. If this command is executed while the player character is engulfed by a 
Beam or 
Blast, the attack will instead bend the other direction, causing the player in question no harm.
Stamina Break
A Stamina Break, also referred to as a Defense Break, is performed if the player blocks and then right-clicks (or presses Y, depending on the player's device). Upon execution, the player's character slowly winds up a punch as an orange sphere visibly shrinks into the character's body. When the sphere completely disappears, the character does a sucker punch; should the opponent get caught by the attack, their Defense bar will be completely drained. While being Stamina-Broken, the opponent cannot do any actions that use up their Defense bar, until they're completely replenished.
A Heavy Stamina Break, or Heavy Defense Break, is an enhanced version of the Stamina Break, where the same command is carried out but the player has to be in MAX Power mode. Upon being Heavy Stamina-Broken, the opponent is forced into stun-lock recovery mode, meaning they are completely immobilized, regardless on whether or not they take damage or knockback, until their Defense bar is fully replenished.
Ki Blast
Ki blasts are tiny orbs of energy that can be fired by pressing F (or B, depending on the device). The balls of energy take up a bit off the Ki bar and deal minimal Ki Damage, but also have minor tracking. Like Beams or Blasts, they can be deflected.
Bars
The bars refer to the interfaces seen on the top left corner of the player's screen.
Health Bar
The Health bar is the green bar that determines the player's Health (or HP), or how much more damage the player can endure. Whenever the player is down to ~15% HP, the bar turns red. Should the Health bar be completely depleted, the player (or NPC) will die, giving them the choice to either respawn with full HP (and other bars full) or go to the Other World.
When locking on a player or a fightable NPC, the player can see their Health bar on the top right corner, which is red instead of green.
For either players or NPCs, ways to lose HP are:
- Getting hit by basic combat, such as punches and kicks.
- Getting hit by Blasts, Beams,
Rushes, 
Counters, or Ultimates. - Getting hit by ki blasts. For enemies, however, ki blasts no longer damage them whenever they're down to 1 HP.
- Getting Stamina-Broken.
- Getting thrown.
- Using any form of Kaioken (from mastery levels Unmastered
to Tier 3
). This is not the case for enemies. - Using Blue Kaioken. This is not the case for enemies.
- Being successfully absorbed by a Majin player. This instantly kills the player, and is not the case for enemies.
- Resetting
character. This instantly kills the player, and is not the case for enemies.
For players, ways to regain HP are:
- Leveling up. This restores the player to full HP (and other bars full as well).
- Using Senzu Beans and Half Senzu Beans.
- Using Regeneration, which is a race ability exclusive to Namekians.
- Using Super Regeneration, which is a race ability exclusive to Majins.
- Standing still, if the player is a Bio-Android.
For enemies, ways to regain HP are:
- Not taking damage for a while after aggro
. - Transforming. Certain enemies such as Frieza and Cooler are capable of doing so.
Ki Bar
The Ki bar is the yellow bar that is below the HP bar, between that and the Stamina bar. It determines how much ki the player has, meaning how many ki blasts or Beam or Blast skills the player can perform. Doing the aforementioned moves uses up the Ki bar, and the usual way of replenishing the Ki bar is charging.
Stamina Bar
The Stamina bar is the dark blue bar that is below the Ki bar. It determines the player's Stamina, or how much they can endure fast flying or using Rushes or Counters. When the Stamina bar is at 15% it turns yellow, and when it is down to 5% it turns red. When it is fully down, the player is unable to fast fly or use Rushes or Counters and loses consciousness momentarily. It cannot be regained by charging. Unlike players, NPCs don't have a Stamina bar, so they have an infinite amount of Stamina.
Ways to lose Stamina are:
- Fast-flying.
- Using Rushes or Counters.
- Being Stamina-Broken.
- Being hit with basic combat by a Tuffle player.
Ways to regain Stamina are:
- Waiting, not doing anything that uses up Stamina. The Stamina bar slowly regenerates over time. Certain Power-Ups can speed up or slow down this regeneration process.
- Using Divine Water and Ultra Divine Water.
Defense Bar
The Defense bar, sometimes called the Evasive bar, is the set of five lavender bars located beside the Ki bar. It allows the player to dodge.
For players, ways to use up the Defense bar are:
- Snap Vanishing. It depletes 1 Defense Bar per Vanish.
- Blocking. This slowly depletes the Defense bar.
- Using an
Evasive. This uses up two Defense bars. - Being Stamina-Broken. This completely depletes the Defense bar, and the player is unable to use up the Defense bar until the bar is fully replenished.
For players, ways to regain the Defense bar are:
- Waiting, not doing anything that uses up Defense. The Stamina bar slowly regenerates over time. Certain Power-Ups can speed up or slow down this regeneration process.
- Using a Sports Drink or Special Sports Drink.
- Using the Power-Up Rise to Action. This regains two Defense bars.
Miscellaneous Features
Beam Clash
Beam clashes (or beam struggles) are triggered when two nearby players fire Beams at each other almost simultaneously.
Upon triggering a beam clash, both parties are instructed to press the F key as fast as they can. Whoever can spam the F key faster than the other wins the struggle, and the losing side gets their beam cancelled out and becomes engulfed by their opponent's beam. The damage of each opponents' beams during a beam struggle gets multiplied by 1.5.
Both players cannot be damaged by outside forces, up until their beam struggle is done.
