Challenge Mode

Current challenge: Harley Quinn/Suicide Squad(ends November 24th)

Required characters: Black Adam, The Flash, and Raven A Challenge or Challenge Mode is a regularly held event that usually starts on Thursday and lasts around three weeks (usually shorter for repeats), in which players must beat 63 (repeatable for two further times at increasing difficulty for 189 total) battles within that time for various prizes, but they are most well-known for unlocking challenge characters, which are the main source of new and more powerful characters for every player's roster. Batgirl is the first known challenge character. Challenges may be repeated. So far, Batgirl/Prime, Darkseid/Prime, Superman/Godfall, Martian Manhunter/Prime, Batman/Beyond Animated, Raven/Prime, Killer Frost/Prime, Wonder Woman/Dawn of Justice, Superman/Dawn of Justice, Black Adam/Kahndaq, Sinestro/Antimatter, Red Lantern Hal Jordan, Lobo/Bounty Hunter, Darkseid/Apokolips, Deadshot, Harley Quinn/Suicide Squad, The Joker/Suicide Squad, Martian Manhunter/Blackest Night and Wonder Woman/Justice League are known to be officially repeated. Batgirl/Prime, Superman/Godfall, Harley Quinn/Suicide Squad, and Darkseid/Prime are the only ones to be repeated at least twice.

Each challenge has five challenge battles; challenge battle 1 to 4 has 12 fights and 5 has 15, including a boss fight against the challenge's unique character. Challenge battles can be done alongside Standard Battle without resetting progress. They can be done in any order, you don't need to complete a battle to work on another, although you still need to beat the matches in order.

Completing 2 challenge battles awards a Bronze Booster Pack completing 3 awards 15,000 Power Credits, completing 4 awards a Silver Booster Pack, and completing 5 awards the challenge character. Additionally, after completing the Standard challenge, you can do the more difficult Expert challenge for the same rewards plus a random piece of uncommon (2-star) gear for completing it. Finally, the Nightmare challenge offers a 3-star gear specific to the challenge character.

However, this was changed as of the 2.11 update, and ONLY happened for the challenges for the Suicide Squad characters; the Standard difficulty contained only 9 battles each, with no characters requirements, except for the Bronze and Silver tiers, which are tier 1 and 2. Additionally, prices for completing tiers have changed for better prizes. Upon completing the Standard difficulty, it will be changed back to normal. After the challenges (and the repeats as well), Raven/Teen Titans's challenge began and Challenge Mode was reverted back to its original way (though still without Challenge Credits).

It is possible to simply pay Power Credits to skip battles. This has a high price however, so try to avoid unnecessarily spending credits during the challenge, as players may be forced to skip some battles they are unable to beat.

Previously, battle 2 requires a random character just like battle 4 and 5 and battle 3 only allows bronze and silver characters, but this is switched around in the Martian Manhunter/Blackest Night challenge. The energy cost was unchanged, however: battle 2 still only consumes 1 bar of energy each while battle 3 consumes 2. This was changed back in Green Lantern/Red Lantern Hal Jordan's challenge.

Starting with the Blackest Night Martian Manhunter challenge, there would be a single match in the challenge that awards an unrelated gold card. It was Darkseid for this case, followed by Batman/Beyond Animated during the Red Lantern Hal Jordan challenge; however, it was changed during and after the Catwoman/Arkham Knight's challenge, so instead of a Gold card, you'll recieve a Silver card instead.

Trivia

 * There are no challenge versions of Ares, Cyborg, Green Arrow, Lex Luthor, Nightwing, and Shazam.
 * On the other hand, there are no non-challenge versions of Raven, Aquaman, Hawkgirl, Martian Manhunter, Scorpion, Darkseid, Killer Frost, Zatanna, Static, The Arkham Knight, and Deadshot.
 * Prior to the release of The Flash/Elseworld (or up till Hawkgirl/Prime), challenges were not repeatable.
 * Prior to the release of Superman/Godfall (or up till Aquaman/Prime), the challenge front page will show the character in a different pose, mostly one of them leaping into the scene. Superman/Godfall and all following challenge characters only have their image on their card reused on the front page instead, although repeats of previous challenge will still use their old image.
 * A glitched version of the challenge battle description will briefly appear upon completing a challenge battle.Challenge glitch.png
 * Deathstroke/Red Son and Zod/Prime were originally announced to have challenge repeats in the lull after Lobo/Bounty Hunter, but was never re-released and instead the 2.6 update brought in a batch of all-new characters.
 * Since August 4th, the record of shortest challenge and/or shortest repeat is held by the repeat challenge of Lobo/Bounty Hunter, which lasted for only 2 hours before it was changed back to Darkseid/Apokolips's repeat as it was supposed to. The second shortest repeat is tied between three characters, Raven/Prime, Batman/Beyond Animated, and Superman/Godfall, who each lasted 2 days as part of a gauntlet event.
