[Free to play: Injustice 2 Mobile] - Solo Raid Dark Nights H5T4 Arkham Knight Batman

Boss AKBM has a chance to stun opponents upon tagging in. It doesn't work all the time, and it is probably further negated with HBHQ's 75% chance to reflect stun. I reckon HBHQ to be the best team to field against this boss. I am generally a FREE TO PLAY player, so I don't own powerful artifacts like beta club, sword of sin & salvation. I work with whatever that is given free.
