Yes, I've heard about criminals posing as Legends, and they're as derivative as they are pathetic. Take this prison break. I admit there are similarities to my modus operandi, but the cloud formations... that's where they went wrong. My gas wafts through the air as if dancing with death. Not like the spray of some hick fireman's two-decade-old extinguisher, as shown here. Anybody with a tenth of my brainpower can see this for what it is: amateurs playing dress-up in a desperate attempt to gain notoriety. But considering your banal, lackluster brand which you dare call 'journalism'? A tenth of my intellect is giving you far too much credit. Do you have any more questions that might illuminate your ignorance? Very well. Enjoy your day.[1]

Abilities[]

Nox Gas Trap[]

Nox Gas Trap.svg Tactical Q/LB/L1
Nox Gas Trap
Description Place up to 6 canisters that release deadly Nox gas when shot or triggered by enemies.
Cooldown 25 seconds

  • You can hold up to three charges of this ability, and gain one charge every 25 seconds. Up to six traps can be active on the map at once, and you're able to pick up unactivated traps to regain a charge.
  • When an enemy gets close to a trap, it releases a cloud of gas that deals 5 Health damage per second to enemies caught within, ignoring shields.
    • Bullets striking the top of a trap will also cause it to go off. However, shooting the base will destroy it without releasing gas.
    • Enemies will be slowed inside the gas and are unable to sprint. Squadmates aren't affected by this.
    • If one trap affects an enemy it will deal 5 damage per second. Nox Gas Grenade.svg Nox Gas Grenades and any other traps affecting the same enemy will only deal 1 additional damage e.g. if three are activated at the same time they will do 5-7 damage per second.
  • The traps can be destroyed while midair or before they're fully inflated.
  • The traps can float away when thrown in moving water.

  • Wattson's Interception Pylon.svg Interception Pylons can shoot down traps in mid-air if they would have landed inside the range of the pylon.
  • Wattson's Interception Pylon.svg Interception Pylons cannot destroy traps that are already fully inflated on the ground.
  • The gas can damage both Wattson's Interception Pylon.svg Pylons and Perimeter Security.svg Perimeter Security nodes.
  • Mirage's decoys can trigger the traps to reveal Caustic's location to his squad.
  • Lifeline's D.O.C. Heal Drone.svg D.O.C. Heal Drone will malfunction while inside of the gas and will not be able to heal anyone.
  • Crypto's Surveillance Drone.svg Surveillance Drone can be damaged by the gas.
  • Rampart's Amped Cover.svg Amped barriers can be damaged by the gas.

  • Shooting the base of the trap before it activates will destroy it without releasing the gas.
  • It's good to throw a trap in a smokescreen generated by a Bangalore's Smoke Launcher.svg Smoke Launcher, especially if enemies are hiding in it. This will also highlight enemies in green due to Nox Vision.svg Nox Vision, and allow you an unfettered view of the enemies.
  • When outnumbered or in a sticky situation, throw multiple traps around you. The enemy's bullets will hit your traps, setting them off, and allowing you to escape or heal to stay in the fight.
  • When going through Wraith's Dimensional Rift.svg Dimensional Rift portals, throw a trap at the end to catch enemies off guard trying to get your squad from behind and reveal their position due to your passive.
  • Throwing a trap in front of a door prevents it from opening to that side. You can use this to block doors and protect yourself, or to trap enemies inside an enclosed room. If they break down the door, the trap will activate and you’ll be informed of their location.
  • You can use your traps as smoke bombs, to throw some cover for sniper fire or general confusion.
  • You can also use your traps offensively when an enemy squad is inside a building, and they are extremely weak. They can be thrown inside through doorways and be very deadly if they are in a small space.
  • A squad that manages to get their Caustic to end game (such as Round 6 as it is almost done shrinking) will have the advantage over other squads that don't have a Caustic. Caustic's abilities increase in utility as the play area shrinks. Furthermore, Caustic can prevent scenarios of Heal Off Victories from happening as it's harder to heal in the gas and ring damage.

  • If you throw the trap underneath you, you'll be in its textures, works with teammates too.
  • Throwing the trap under Lifeline's Care Package.svg Care Package before it lands will cause the trap to slowly fly away.
  • Occasionally if you or a teammate touch a recently placed trap, It will begin to slide away.
  • Placing a gas trap right next to a closed-door when the player is right next to the door or when a trap is deploying next to a closed-door that is propped open causes the player located where the trap was deployed to be crushed.
  • Gas traps which are deployed on top of Gilbratar's Dome of Protection.svg Dome of Protection will stay "floating" at their positions after the shield is gone.


  • Nox Vision[]

    Nox Vision.svg Passive
    Nox Vision
    Description You gain threat vision on enemies moving though your gas.
    ?

    • Caustic is immune to the effects of Nox Gas whether it belongs to him or an enemy Caustic.
    • Enemies inside the gas created from your Nox Gas Trap.svg Nox Gas Traps and Nox Gas Grenade.svg Nox Gas Grenades abilities are highlighted green, similar to Digital Threat Optics. This vision is obstructed by walls or other obstacles.

  • Your squadmates do not share this vision, so be sure to communicate to them the locations of enemies you can see.
  • Your threat vision doesn't work against other Caustics, forcing you to prioritize them, as they are immune to all Nox Gas effects and they can see your allies even if they are in your gas.


  • Nox Gas Grenade[]

    Nox Gas Grenade.svg Ultimate Z/LB+RB/L1+R1
    Nox Gas Grenade
    Description Blankets a large area in Nox gas.
    Charge time 3.5 minutes

    • Deals 5 damage per second spent in the gas.
    • Other than the wider area of effect, the gas's function is identical to that of Nox Gas Trap.svg Nox Gas Traps.

  • The grenade can be shot down by Wattson's Interception Pylon.svg Interception Pylon. However, if the grenade has already detonated, the pylon can't block any of the gas, and will even take damage from it.

  • Do not use Nox Gas Grenades and expect them to kill an entire squad. Similar to Bangalore's Rolling Thunder.svg Rolling Thunder, its main utility comes in the fact that enemies are forced to either evacuate the area or suffer the consequences of damage, the inability to sprint and being highlighted by Nox Vision.svg Nox Vision.
    • Since gas deals damage and slows enemies, use Nox Vision.svg Nox Vision to hunt down and kill them while they are weakened. If you have Grenades, throw them into your gas when an enemy is caught-- this combo has the capability of wiping out full squads if enough players are caught in your gas.
  • Using this ability in large, open areas is often a waste. Try to save it for when enemies are occupying a building, a small area, or are hiding behind a cover too dangerous to bypass.
    • You can also use this ability to block chokepoints or cover/punish revives.
  • Try saving this for the last few rounds as his abilities increase in utility as the safe area shrinks. Furthermore, he can prevent scenarios of Heal Off Victories from happening as it's harder to heal in the gas and ring damage.


  • Fortified[]

    Fortified.svg Perk
    Fortified
    Description Incoming damage reduced by 15%. Not slowed by bullets.
    ?

    • Take 15% less damage from every attack.
    • Immunity to slow effects from weapon fire.

  • Don't overestimate this ability, 15% less generally translates to surviving 1 more shot.


  • Lore[]

    Alexander Maxwell Nox was born to Arthur Rutherford Nox and Katerina Ticacek Nox on February 25, 2685.[3] He worked as a research scientist for Humbert Labs on his homeworld Gaea[3], the Frontier's leading manufacturer of pesticide gases. With a glut of pesticides needed to protect the growing Frontier colonies’ crops, Humbert Labs was constantly on the hunt for better and stronger formulas. Nox was one of their brightest scientists and worked day and night developing new gases. But to make sure they worked, he needed to test them on more than just inert tissue: he needed something living.[4]

    As he toiled in secret, Nox began to see the beauty in his creations and their ability to destroy anything they touched. But the head of Humbert Labs, Dr. Franklin Humbert, soon discovered his gruesome experiments, and their confrontation ended with the lab in flames and its chief dead in 2723[5]. Today, Nox is missing and presumed deceased, his supposed body found and identified by his mother, charred and beyond recognition.[3] 10 years later, Caustic now finds new test subjects in the Apex Games, where he puts his gaseous creations to work and observes their effects with great interest.[4]

    History[]


    Trivia[]

    • His global identification number on Gaea is: ARN0-225P-ER9.[3]
    • When he registered in the Apex Games as a competitor, he utilized the name "Dr. Mikhail Caustic".[6]
      • His alias' bio stated he was born in 2690, educated and graduated in 2715, received his Ph.D. in 2720, and won the Heinrich Hammond Award for Excellence in Science on Psamathe in 2725, before doing a sabbatical in Solace.
      • Despite using an alias in the Apex games, Jacob Young (syndicate's Director of PR) refers to him as "Nox".
    • The case file on Gaea indicated Caustic is diagnosed by multiple medical practitioners as a medically confirmed psychopath.[7]
      • This, or possibly other psychological issues, resulted in the rejection of his self-applied application for being turned into a simulacrum.
    • Caustic has cancer at a stage that he himself considers as incurable. Before the confirmation in the "Legacy Antigen", it had been hinted through a voice line, where he says he has faced his death, right before going into a hacking fit.
    • Although not visible due to his gloves, Caustic is likely missing at least two fingers. On his death record, the examiner states that two severed fingers were found near to the left hand of the corpse and matched Nox's DNA.[3]
    • For some reason, Caustic's eyes appear to glow in the dark. It is currently unknown why but could have to do with his Nox Vision passive ability.
    • In the discussion getting Revenant into the Apex Games, Caustic was discussed as having gone soft since some girl joined the games, most likely Wattson. [8]
    • As explained by writer Tom Casiello, the Nox Gas is a corrosive gas, that eats through clothes, skin, and metal, unless countered by a chemical compound only he possesses so it doesn't affect him, which explains why the gas still affects Pathfinder, Bloodhound, and Revenant. Because that is the case, it is unknown why he needs his gas mask, though it is likely to hide his identity as he is presumed dead. [1]
      • His gas contains agatoxins from Carthage Spiders, a mammoth class arachnid found on Gaea that emits toxic gas from its abdomen. The Agatoxin is similar to the Medusa virus.
    • According to Manny Hagopian, Caustic's name was originally supposed to be "Alexander Gaskins" based on the serial killer Donald Henry Gaskins. It was changed to "Nox" after it was pointed out that "Gaskin" has the word "gas" in it and Manny agreed it felt weird.[9]
    • An inappropriate voice line between Caustic and Crypto was removed in the September 03, 2020 Patch; where Caustic says as thanks to Crypto, “You’ll regret the day you crossed me, gutter rat,” due to the word “rat” being a racial slur towards Asians.
