Dulk Fakis is the boss for HIVE and has two forms. The first form is stationary and sits at the end of a ramp. It will cast random technics and pound enemies with its arms. Also, it can emit a powerful laser beam. Be sure to look out for the low-level Megid that the tentacles on the side of the room cast. Finally, this form can erect a shield to protect itself.
If you are fighting against Fakis offline or online on S-Rank, you will face a second form. This form possesses photon wings and a second head on a long, scorpion-like tail. It attacks with its tail, various charges, and a beam. Be sure to keep an eye out for its devastating meteor attack!
