Q: How do the Gladiator badges work?

A: Gladiator badges unlock different critters a player can summon in our new (pet) arena. In this battle, two players command hordes of mobs that battle to the death. At the moment, these creatures are drawn from City of Villains lore; these include the mysterious Coralax, the arcane Hordelings, and the countless Arachnos troop types. We'll be adding more in the future. Some Gladiator badges are earned by defeating certain types of mobs, visiting different places in the world or winning matches in the Arena.
