Wanted! The Corps seeks the defeat of Green Lantern Kilowog. Considered a serious threat: do not approach alone.
Kilowog is a standard bounty kill. As he is high level expect to take a large amount of damage if you're the one "tanking" him. One of the most paintful moves is the weight drop, if you're not a tank or blocking, this will take off a good few 100 hp easily. He also uses the fan blowback and ground pound knockup/stun, both are easily breakout-able so just keep your cool.
Top tip is to kite him away from the other Lanterns near the city hall, just pulling him east across the road junction would do.
Suggested full group with healer and tank.
Good luck and have fun!
