Passive Best Served Cold: Killer Frost dampens all opponent's power generation by 50%.

Killer Frost Prime is a versatile character, wielding the most powerful debuff ability in the entire game and highly differentiated basic and special attacks. She is definitely a "cool" card to have in your arsenal.

Currently both versions of Killer Frost (along with Killer Frost/Regime) are Challenge characters, her challenge having last re-aired in March, but she is known to be a guaranteed pull in the Ice Breaker Pack. However, obtaining her from a pack will not unlock her for direct promotions.


Killer Frost Prime offers a lot to her team besides her powerful static debuff: she has one of the strongest combo enders in the game, and each of her special attacks has very useful effects without the normally associated damage penalty. She can be geared effectively with any of her attacks in mind.

Passive Edit

"Best Served Cold" reduces the power generation of each member of the opponent's team by 50%. This seems to be done on an additive basis, meaning that a character equipped with the fully fused The Ibistick (which gives a 30% power generation increase when fully maxed out) but with no other power generation boosts will generate power at 80% the normal rate. This effect stacks with the freezing effects that come on both of Killer Frost/Regime's specials (which also will reduce power generation by 50%), meaning that, without an effect increasing power generation, Prime Killer Frost can allow opponents' power generation to be frozen to absolutely 0%. It is not stated in her passive or in the description of the move, but Killer Frost/Prime's SP1 actually has the same freezing effects as those mentioned in her Regime counterpart's passive (see below in Special Attacks and Interactions).

Her passive will work if she is on your team, regardless if tagged in, out, or KO'ed.

Basic Attacks Edit

Basic combo Damage pattern (% of damage stat) Total (including Combo Ender)
Light (Combo Ender) 2% - 2% - 2% - (4% - 4%) 14%
Heavy 4% - 4% - 2% - 2% 12%
Black Ice

The third hit of Black Ice is UNBLOCKABLE.

Killer Frost has an excellent light basic attack pattern: not only does she have a two-hit combo ender, but each hit also does 4% of her damage as a base as opposed to the normal 3%. As such, Ra's Al Ghul's Scimitar and Gauntlets of Azrael are both excellent gear choices for her, and can be used independently or in conjunction with each other. She can drain power twice as fast as any character with a 1-hit combo ender with the Scimitar, and she can heal through the Gauntlets 2.67 times faster than the average character with the same damage stat.

Her heavy combo is interesting: it deals 12% of her damage as a base same as the typical heavy combo, but it does so in 4 hits instead of in 3.

Special Attacks Edit

As mentioned above, her SP1 slows the opponent and further (additively) cuts their power generation by 50%. This effect cannot simply be blocked, and will pass the effect on to the next opponent if the last hit achieves a knockout. Without a further source of power generation, the opponent's power generation is zeroed.

Her SP2, meanwhile, is one of the only specials in the game to always be (partially) unblockable without any penalty or reliance on passive. Thus, many often geared her up to use this special if they can.


Please note that battles are highly situational: this section only mentions cards that have mechanics that, for any reason, are particularly effective with/against, or particularly ineffective against Killer Frost. Having a card that "counters" Killer Frost does not mean it is always a good choice.

Good withEdit

  • Wonder Woman/600: Her passive gives Prime Killer Frost 30% more damage and power generation; with some gear, her entire team can be gaining power at about three times as fast as the enemy team - they won't be able to quit fast enough.
  • Killer Frost/Regime: The pair of suffocating team-wide debuffs are simply an immense pain to fight against. Prime Killer Frost's s2 in particular is a large amount of unblockable damage that is just not recoverable against Regime Killer Frost's healing reduction. Indeed, Regime Killer Frost, 600 Wonder Woman and either one of Prime Killer Frost or Cassandra Cain Batgirl are common teams on multiplayer defence and are quite possibly the most frustrating opponents there could be.

Black Ice daggers

The ice daggers are still flying towards her opponent despite they have already been knocked down by the dash.

  • Killer Frost throws two ice daggers during Black Ice and follows up with a dash into her opponent. However, as the daggers have a very slow missile speed (while the dash is fast), if she knocks back her opponent before using Black Ice, it is possible for the daggers to hit after the dash. Occasionally, the daggers may hit so lately it becomes outside of the special's time range, turning its damage type from yellow to white. It appears that stun on s2 from gear cannot be applied if the special has been changed like this. While the daggers momentarily stagger the opponent after the special ends, it is too short to take advantage of.
  • During the 2.10.1 update for the Catwoman/Ame-Comi's Challenge, since 2 of the requirements were Bane and Killer Frost, the long-awaited Ice Breaker Pack has finally been added into the store as a way for players to obtain these 2 characters, and also mark the first time that she's available in ANY pack.
  • She can potentially reduce her opponent(s)' power generation to 0% as long as they don't have any extra power generation from gears or teammates; if her opponent does, they will only generate as much power as the extra power generation allows.
