Atlantean Hero is Aquaman's (Prime) second ability in Injustice Gods Among Us. It is an OK move but leaves you hanging afterwards.
Upon activiting the 2nd special, an Atleantean servant fights for Aquaman. The Warrior deals a bunch of fucking damage but has BS health points. Aquaman can do this multiple times.
If it's upgraded, it IS VERY ANNOYING. It's too OP.
