brute fucking justice

Onslaughter:
Hydrothermic Missiles - Fires homing missiles at the party
Seeds of the Sky - Fires blue orbs into the air, which then fall down and explode.
Megabeam - Fires a Big Fuckin Laser. Pretty much a OHKO.
Execution - Creates four areas on the arena, each with a Steam Regulator. After 20 seconds the regulators will explode and wipe the entire party out if they aren't destroyed. Players who go into the areas will take a debuff that makes it so that only they can hurt that specific regulator, and are also tethered to the regulator and unable to leave the area
Perpetual Ray - Fires a big AOE attack of energy multiple times. The first hit deals a vulnerability debuff.
Legislation - Tethers players to energy balls that home in on them. if the players touch the balls they are tethered to, they will just die instantly. The only way to get rid of the orbs is to walk into the orbs tethered to other opponents, causing an explosion. Also applies a debuff that can only be removed by taking a certain amount of hits, which is randomized for every player
Illegal Operations - Lets Onslaughter kill the entire party if they meet certain conditions, relating to the abovementioned debuff. These include dying while having the debuff, letting the debuff's timer run out without having gotten rid of it, and moving onto the next phase while someone still has the debuff

Blaster:
You're Just Fucked From the Start - As soon as Blaster's fight starts, he casts a debuff that makes one player more vulnerable to magic damage.
Mind Blast - Fires a burst of energy that confuses the entire party
Mines - Fires four mines into the air, which then crash onto the arena. Two of the mines remain visible, while two turn invisible. After a short while, the mines will explode.
Mirages - Makes mirages of himself drop down on four random players, which then dash off towards four OTHER random players. Also deals a damage down debuff, because Blaster hates you all
Mirages & Mines; Together at Last - Summons five mirages of himself, which start to fire mines all over the arena. They also cast the damage down debuff if they aren't destroyed in time.
Up or Down - Summons mirages which tether themselves to players. These mirages will either be raising their arms, or crouching down. Raised arms means they're going to cast the debuff, while crouching means they're going to dash. The players must either turn away or look the mirages head on in order to stop them

Brawler:
Hand Attachments - Summons four different hand attachments, each representing a different attack. Single Buster fires a large beam, Double Buster fires two large beams at the same time, Single Drill has Brawler fire a drill at a single opponent, and the Double Drills fire at the nearest and farthest players relative to Brawler.
Steam Chakrams - Summons up to three floating steel chakrams, which spin around the stage. Standing under one will cause it to shoot electricity, paralyzing the player
Brawler's Balls - Once his health is depleted, Brawler will become invincible, and then start summoning multiple waves of orbs, all while trying to attack you with his normal attacks. If one of the orbs reaches Brawler, it will explode and deal damage to the party. There are multiple types of Orbs. Power Plasma Alpha will deal damage and debuffs if it gets to Brawler, but can be destroyed. Power Plasma Beta cannot be destroyed, and will deal damage to the entire party if it reaches Brawler. Power Plasma Gamma will deal splash damage when destroyed.

Swindler:
Raising and Lowering Prices - Fires out two different waves of buffs, which have to be avoided by standing on differently leveled parts of the arena.
Stacking Circles - Casts two circles on two players, which will kill them after a  while. A certain number of players, represented by the number of orbs over the affected player's head, need to enter the circle in order to get rid of it
Bio-Arithmetics - An AOE attack that covers the entire arena, signaled by a bunch of orbs showing up

Compressed Elements - Casts Compressed Lightning and Compressed Water debuffs on two players. i have no idea how the rest of this attack actually works at all even after watching this guide sorry
Fire - Fires pools of fire at certain opponents. Fire pools remain on the arena for a while. Vortexer will also shoot out fire beams.
Ice - Like the fire attack but with ice, and without the beams. Can freeze a water spout created by Compressed Water apparently.
Super Cyclone - Burst of wind that pushes player away
Ultraflash - Creates a burst of light that destroys basically everything on the stage, including debuffs and buffs.Then he just starts repeating

Combaticons Together:
They're One Boss, Idiot - In the original fight, the Combaticons act as a single boss encounter, meaning you have to defeat all four of them without wiping out, or their timer running out

We Just Fucking Hate You - In the Brute Justice fight, if all four Combaticons are in the arena at the same time, they will explode and insta-kill everyone
