Sub-Zero is a 3-star base gold Arcane hero. A cryomancer capable of making endless copies of his opponents, he is a slippery and enduring combatant and a fearsome giant-killer when used well.
His shards can be obtained through Challenges.
Official description
Grandmaster of the Lin Kuei, Sub-Zero can create a clone of his opponent to fight for him in battle. Also, using an ice ball, he may freeze his opponent, stopping the victim's power generation and allowing for a follow-up attack from himself or one of his teammates.
Strategy
An example of a seemingly insurmountable battle that Sub-Zero could (and in this case, did) win.
Sub-Zero is incredibly powerful when facing opponents with much higher stats, particularly those with weak passives. His ice clone essentially steals most their stats for his use. In fact, his worst enemy is often the countdown timer, especially against high defence teams; however, it seems as long as his team does more damage, he can still win in Arena matches when the time runs out.
Normally, you're invulnerable and the enemy can't start a special while you're using a special. However, if Sub-Zero is far away from his opponent, Klone Toss would take a long time to reach his opponent and the latter would be able to use ranged basic attacks or a Supermove before it could it. This can KO Sub-Zero, which would prevent a clone from being created (although they would still be briefly frozen).
When the countdown timer runs out in Arena, if you win with a clone, the game would automatically tag in Sub-Zero to perform the winning animation. This led to a misconception that you must tag out the clone at the last moment to win, which is not the case.
Interactions
Good with
- Power generators/cost reducers: Doctor Fate, Power Girl or Emerald Green Lantern is good for him due to his power reliance. Doctor Fate is especially good because of his infinite 3-hit ranged combo than can pin down opponents without ranged specials. Normally this runs the risk of taking a supermove, but Sub-Zero can tank it with a clone.
- The Joker: Especially when facing extremely strong opponents, the combat capabilities of the third hero (other than Sub-Zero and Doctor Fate) becomes less relevant and The Joker can still be useful suicide-bombing with his passive, giving you 1 bar of power and stunning the opponent, giving you breathing room and vitally, interrupts specials that can normally deal multiple KO blows and would otherwise hit Sub-Zero.
Good against
- Heroes with strong effects that do not rely on their passives or supermoves.
- Heroes with Special block, such as Wonder Woman, Gorilla Grodd, Superman, and their variants. However, if special blocked, the ice clone will not freeze the target, reducing your time to react. Especially noticeable since using Klone Toss, like all specials, incur a global special cooldown - if Sub-Zero's opponent is not frozen, they can immediately use a special to KO the clone, and if you have the cooldown you can't block it with the clone's special block.
- Black Adam: When cloned, his Electric Burst Ability still has a chance to steal power bars, and Lighting Cage can still activate the power cost reduction buff. Note that if Doctor Fate, Power Girl, or Black Adam are on Sub-Zero's team, they do not affect his clone, but if his clone copies an enemy Black Adam, the clone can activate its own power cost reduction buff that will apply to Sub-Zero and his team as well while it lasts.
- Soulstealer Doctor Fate: He may waste his supermove and passive against Sub-Zero's clone; as the clone is created at low health, Soulstealer Doctor Fate would likely damage himself and heal the clone, and if the clone has high defence it might even survive the super. Sub-Zero's clone can heal itself using his Break of Life, however, the heal is very low and inefficient.
Countered by
- Heroes with good specials that can deal multiple KO blows (so it could KO the clone and also hit Sub-Zero), one example being Multiverse The Flash's special 3.
- Last Laugh The Joker: a clone being KO'ed will activate Joker's passive, giving him bonus damage.
- Horrific Scarecrow: Increases his power costs, which cripples his effectiveness.
- Justice League Batman: His passive allows all Justice League teammates to ignore one special, which prevents Sub-Zero from creating a clone.
- Armored Superman: Same as Justice League Batman, but he only ignores one special for himself.
- Black Adam: Same as Horrific Scarecrow, but more randomly from specials. His Lightning Cage buff (reduces Black Adam's team's power cost by 3) and Electric Burst's power steal is also very difficult for Sub-Zero to handle.
