Health

Health is one of the two main stats in Injustice mobile, along with Damage. Health represents how much damage a character can take before they are knocked out and removed from the match.

All characters have a base health, which is their health at level 1, without promotions and support cards. This ranges from 180 (Catwoman/Regime, Flash/Prime and Flash/New 52) to 1400 (Wonder Woman/Dawn of Justice, Darkseid/Apokolips and Red Lantern Hal Jordan ).

Increasing health
This can be increased by leveling and promoting the character. At level 50 and elite VII, their health would becomes 54 times of their base health (x10.8 from levelling, x5 from promotions). This value is roughly 25.92 and 41 for bronze and silver cards respectively.

Support cards
All characters have unique support enhancement cards bought with Power Credits that modify their health stat (+10%). For example, Superman is affected by the Lois Lane card, which increases his health stat by 10%, while Son of Krypton increases his damage by 10% and Fortress of Solitude increases his energy regeneration by 10%.

Additionally, alliance support cards bought with Alliance Credits affect all characters. The health alliance support cards include Kilowog (+3%, 5 credits), Hawkman (+4%, 15 credits), Black Manta (+5%, 25 credits), Parallax (+6%, 35 credits), and Swamp Thing (+7%, 45 credits).

This adds up to +35% health total.

Trivia

 * When Damage or Health stats exceed 10,000, they are represented with K for thousand, so 10,000 becomes 10K. This is always rounded down. And if a character's stat passes 100,000, it will be displays as 100K.
 * Batman/Arkham Origins in the final match in battle 49 (the last battle in the game other than Bonus Battle 7) has the highest visible (i.e. non-Survivor) and permanent (i.e. non-challenge) health stat in the game, at 251K (the burn from The Ibistick suggests 251,500).
 * Very high match Survivor opponents can have over 1000K (over 1 million) Health, although they can have gear to modify their max health.
