 This One's For Mr. J!: When the enemy tags-in, Harley may perform a surprise attack (if she is tagged out).If The Joker's knocked out on Harley's team, she gains full POWER. |
Arkham Knight Harley Quinn has the second-highest base stats out of all Harley Quinn characters; while she doesn't have a team-wide buff, her unorthodox passive is useful in a variety of ways, and she is one of the 4 characters (along with The Arkham Knight, Deadshot, and Wonder Woman/Dawn of Justice, although The Flash/Metahuman only counts upon using his specials) to have a 3-hit Combo Ender.
She can be unlocked through Challenge Mode. Otherwise, she can be obtained randomly from the Arkham Pack or as a guaranteed character in the Arkham Knight Harley Quinn Pack, or a possible chance in the Wally West Gold Pack but neither will unlock her for direct promotions, despite the wording on the latter.
Harley Quinn's passive activates at random when an opponent tags in while she is tagged out.
Strategy
| Basic combo | Damage pattern (% of damage stat) | Total |
|---|---|---|
| Light (Combo Ender) | 2% - 2% - 2% - (3% - 3% - 3%) | 15% |
| Heavy | 4% - 4% - 4% - 4% | 16% |
The damaging aspect of her passive has an estimated ~35% chance of triggering on any tag in (knock out blows do not count), as long as she is currently tagged out. It does multiple hits, adding up to 60% of her damage stat; in comparison, a fully upgraded and unblocked special 1 at 200% damage will do 66%. It will stagger her victim and grant power to both Harley and her target as if Harley has hit them with that many basic attacks. It can be blocked. Characters who triggered her passive cannot use specials, even when she was still running up and has not started firing yet. It can knock out opponents and continue to damage the next opponent. The damage will register as Harley's teammate's damage, not Harley's, and cannot crit from basic or global crit sources.
It will trigger Raven/Prime's passive. When activated, Raven would swap health with the character currently tagged in, not Harley.
It does not interact with Black Adam's passives; it will damage him without negative consequences and his lightning shield will not be removed.
Her passive can knock out The Joker/Prime and The Joker/Insurgency on the enemy team without taking damage.
It is possible to tag in Harley the exactly same time her tag-passive is triggered; in that case, the previous character will be tagged out, but Harley would not officially tag in until she's done firing at her opponent and exits the screen.
She can gain full power twice from the second part of her passive if teamed with two Jokers. The Fourth World Set's resurrection will not count. However, The Joker/The Killing Joke already grants full power to both of his teammates upon knockout.
All versions of Harley Quinn share a unique Special 2, Bag-o-Tricks; for more information on it, see that page.
Arkham teammates
Arkham Knight characters DO work with Harley Quinn/Arkham (although Arkham Knight Harley Quinn's s2 is already unblockable), The Joker/Arkham Origins and Bane/Arkham Origins's Arkham teammate passives per update 2.8.
Upon Joker's KO'd on her team, Harley gains full power!
Gear
Like all Harleys, her personal gear is almost mandatory. Equipping her with power generation as well so she can constantly use her sp2 to heal your whole team, especially due to her passive allowing her to do a lot of hits.
A basic damage oriented build for Arkham Knight Harley Quinn is not unheard of, as she has a rather high damage stat for a female and she has the second-strongest basic combos of all female characters, allowing her to surpass them in basic damage output (her heavy combos deal the equivalent of a character with 1467 damage and a normal 3 hit 4% combo, and if she gets her combo enders, her light combos is equivalent to 1833 damage).
Ra's Al Ghul's Scimitar and Gauntlets of Azrael can be decent for a utility based build as she is one of only three characters to have a 3-hit combo ender, but that only leaves one slot for revolvers and none for basic damage/crit gear to work with gauntlet's lifedrain. Since her s2 already heals for a lot, you may consider forsaking gauntlets first.

Trivia
- Her artifacts are: Explosive Pie, Boots, Keepsake, Machine Gun, Bat.
- Her challenge is titled "Arkham Knight Harley Quinn" as opposed to the typical "Harley Quinn Arkham Knight".
- If combined with Sinestro/Antimatter, each time the opponent(s) tag out, she will attack them as described, and per chance, she might even KO'd them solely due to her passive.
- Since it is possible to KO an opponent with her passive, thus it can be use that way to complete the achievement "This one's for Mr. J", also, its possible that the name of her passive is the same as that achievement.
- The name of her SP1 can possibly be a reference to a well-known cutscene from Batman: Arkham City, where Harley thrashes Batman with a bat in a manner similar to the special move while also saying the words, "Batter Up!"
- If her passive activated and you tag her in, the camera will heavily bug out and go out of bounds of the arena.
- She's the only version of Harley Quinn that doesn't do a cartwheel on her combo-ender.
- She was the only version of Harley Quinn that doesn't have a 2-hit heavy attack before the introduction of Harley Quinn/Suicide Squad (who has the same heavy combo).
- She has the same base stats as Hawkgirl/Regime.
