Injustice 2 Mobile Champions Arena

What WB says the mode is

Champions Arena is the competitive ladder inside Injustice 2 Mobile. Fights can be a single round or several. You sit in a division, and rank moves you up or down. You set an attacking squad and a separate defending squad. Energy limits how often you can push. At the end of a season the ladder pays rewards. The article says the mode has left beta.

The line I want to keep verbatim in spirit: defense scores. The guide says that, for the first time, you earn points when your defending team beats the attacker. There is a battle log, and you can revenge someone who beat you.

What I will not add

Search interest in this mode is stable, and the official article is already long. Copying every reward table would not help, and I do not have a newer table. No public note I opened describes a 2026 change to payouts or rules. If your question is whether the ladder still exists, the support article is still up and still describes a live mode. If your question is the exact gem payout this month, that number is not on this page.

The other Champions Arena, the one with GalaChain and a January 2026 sunset, does not share characters, energy, or divisions with this ladder. Use the name index if you are still unsure which result you opened.

Practical reading order if you play Injustice: set the defense squad before you care about revenge, watch the energy cap, and expect the season to close on WB's clock rather than a Gala season. I am not repeating gear scores or character tiers from community spreadsheets. Those sheets are a different hobby, and they were not the document I checked.
