Challenge Mode/Superman Godfall/Standard/Challenge Battle 5

Doomsday is required in all matches of challenge battle 5. There are three possible characters you could choose: Doomsday/Regime, Doomsday/Prime and Doomsday/Containment. While Regime Doomsday is given by the Starter Pack, he is a silver card and thus has much lower stats and he has a poor passive. Prime Doomsday is a very strong card especially for new players, and he is always available for purchase (while Containment Doomsday can only be found rarely in Challenge Booster Packs and the Most Wanted Pack, if you haven't unlocked him from his challenge over a year ago; it is not practical to try and get him solely for this challenge), so he is the best to go for if you don't have a good Doomsday card already.

Match 1

 * Cyborg/Teen Titans
 * Wonder Woman/Regime
 * Doomsday/Prime

There is a bug where the first match would display the opponents from the second match.

Teen Titans Cyborg regenerates health whenever he is tagged out. His s1 is a stun, which means it deals only half the normal damage (but remember to block it or you may be stunned). Both of this and his lowest damage stat encourage you to allow Cyborg to be in the fight and let him hit you to gain power. Regime Wonder Woman generates a small amount of power whenever she blocks an attack, so it's best for new players with no basic damage gear to just let her hit you so you can get power quickly. As always, look out for Doomsday. His s2 is quite fast, and he heals by 50% of his maximum health when he knocks out an opponent; however, since this obviously as no effect when he is already full, you could opt to sacrifice a character at already very low health to take that hit when he first tags in (2 characters with high health is safer than 3 characters with low health against Doomsday).

Match 2

 * Zod/Man of Steel
 * Green Lantern/Red Son
 * Green Arrow/Arrow

This fight can be a bit of a drag, as Man of Steel Zod and Red Son Green Lantern have decent health and their passives further reduce special and super damage by 20% (Green Lantern is additionally immune to stun and crit), and Arrow Green Arrow has a power drain s1. They don't do much damage though, and shouldn't be too hard. Credits: 290

Match 3

 * Aquaman/Regime
 * Black Adam/Regime
 * Lex Luthor/Krypto

Regime Aquaman's passive doesn't work here, but remember to tag out your character immediately after he uses his Trident Toss s1 to avoid the damage over time (and +20% additional damage taken from all sources while the bleed lasts).

Regime Black Adam's Lightning Shield is more than just annoying - it reflects twice the damage of special 1s used against it (and 75% of anything else), so you will kill yourself very quickly if you use them on him while his shield is active. Pop the shield (lasts 3 hits) with basic attacks (but be careful and ready to block his specials if applicable), then destroy him with a super when it is down. An unexpected danger is when you are about to use a super, but Black Adam tags in at that moment to take the hit and you will take 75% of your super's damage, which could be devastating. While tagging is somewhat unpredictable, the first character (Regime Aquaman in this case) tends to tag out when they reach 50% health.

Krypto Lex Luthor is a powerful support, with his frequent and strong s1 power drains, and his passive gives his whole team +30% maximum health. Credits: 310

Match 4
Challenge: Chaos!
 * Killer Frost/Regime
 * Catwoman/Batman Returns
 * The Joker/Insurgency

Easily the hardest fight yet. Regime Killer Frost reduces all healing by 90%, which is crippling to any card with good healing - particularly the very Doomsday that is otherwise the best candidate to this battle overall, whose great strength (especially to new players) comes from his huge heals. In the very unlikely event you have Containment Doomsday, he is a much better character in this match as his resurrections are not affected by her passive.

Similar to Regime Aquaman, Batman Returns Catwoman's s1 causes her victim to bleed - which is worse here since Chaos prevents you from tagging out at will.

Knokcing out Insurgency Joker causes your character to lose 40% of their maximum health that can't be avoided or reduced by most means, especially painful when Regime Killer Frost's debuff. Try knocking him out with a character who already has very low health, since this can't knock them out. They will stay at 1 health, and can still be used to tank a special.

Match 5
Credits: 350
 * Doomsday/Prime
 * Bane/Luchador
 * Sinestro/Green Lantern

Doomsday is significantly more dangerous to fight when he is the first character; since the first character usually tags out at 50% health, it gives him a very good chance to wait for two bars, tag in again to knock out one of your characters with Earth Shake to recover almost all his health. His two teammates are also notorious for dangerous bursts of damage: Luchador Bane has a high chance of an unblockable stun when he tags in and also gains 25% damage; Green Lantern Sinestro's next special gains +50% damage if you tag out against him.

Match 13
Credits: 510
 * Catwoman/Batman Returns
 * Batgirl/Cassandra Cain
 * Wonder Woman/600

Match 14
Credits: 530
 * Scorpion/Mortal Kombat
 * Cyborg/Teen Titans
 * Solomon Grundy/Boss

Try to knock out Boss Solomon Grundy quickly instead of letting him stay at low health, as his basic attacks gain exponentially more damage the closer he is to defeat. At critically low health, his heavy basic attacks can do 1663 damage (or almost 5000 with a single heavy combo, easily half of a normal gold card's maximum health).

Match 15

 * Superman/Godfall

This is the final battle, defeat him in order to get 1 copy of Superman Godfall. While there are no handicaps (the Regeneration handicap is part of what made the Martian Manhunter challenge boss so difficult to beat), Godfall Superman still has a huge amount of health for new players; easily taking 5+ super moves for normal, non-elite gold cards. Assuming equal stats, Containment Doomsday is a stronger option here as Doomsday's passive is useless on a single boss. His resurrections are also ideal for absorbing Godfall Superman's one-hit 7000+ damage Flying Punches. However, as stated before, it is not practical to try and get him solely for this challenge. As he has high health and is not accompanied by other characters, cards dealing % maximum health damage (The Joker/Prime, The Joker/Insurgency, Raven/Prime, Batgirl/Cassandra Cain) is very effective. Out of those, Insurgency Joker is the most practical; he is a common drop from Gold Booster Packs (so new players have a decent chance of getting him) and is significantly stronger than Prime Joker. While Raven and Cassandra Cain Batgirl are much stronger, they are much more difficult to obtain, especially the latter.

Godfall Superman will cause him to take further halved basic damage while he is blocking and reflecting the other half back to you. However, this grants you a lot of power, so it is actually advantageous to you if you can get him to block your basics (which won't do too much damage to you if you are a new player with barely any gear).
