Starting in the third phase, increasing amounts of blue sparks will appear in various locations on the boss as it switches phases, and it begins to move and attack faster.
It has 5 phases, changing every 20% health lost and gaining and losing various abilities in each phase. The Darknik Dreadnought Mk II has a mix of melee and ranged attacks, using a variety of guns and bombs throughout the fight. It appears to be more thickly armored and better covered than the Spike Walker, however. The Dreadnought's structure is similar to the Spike Walker, being quadruped with 2 pairs of legs on the sides. It has two small missile launchers that can come out from its sides, and near the top a circular "eye" moves along fixed rails around the front of the boss, much like a Punchbot, which has a cover over it for protection. Behind the Dream Monster hatch, it has a second hatch which houses an autocannon, and above it has another compartment housing a shotgun.
It has a metallic hatch similar in appearance to the Dream Monster's jaw from which various blades come out throughout the fight. It has a light blue cockpit on the upper front, while the bottom appears similar to the Dream Monster's head. The Dreadnought has a somewhat simple appearance, being primarily a large enclosed body, rounded at the front and back but flat on the sides, top and bottom.
