The event also offers new costume stylings for the first superpowered people resulting from the exobytes and a new trial for players to take on during the struggle against the Anti-Monitor. There are even new artifacts and adjustments to old content to make sure that this anniversary event is even better than last year’s event. Jump on in if you want to celebrate another year turning over or if you can’t spend another minute in a game without a super-powered pup waiting at your lair.
If you’re a villain, just assume you kidnapped him.
