Possessed Thunk

The Possessed Thunk is a boss encountered in the Dark Cave of the Darland Ascent. It is one of the One Concern's Kerthunk machines that has been possessed by Eyes. The Possessed Thunk attacks and behaves very differently under the influence of the Eyes than by a Concern Controller.

=Story= After Robin is knocked out of The Tower and into the Dark Cave by the Silver Watchman, she starts searching for a way out. Several times the glowing red eyes of the Possessed Thunk are visible momentarily, foreshadowing its encounter. When activating a Power Supply to turn on lights, she accidentally illuminates the Silver Watchman, who also appears to be trying to escape the cave. With his location revealed, the blue Eyes around attack him. He blinks away to an unknown location. Robin later encounters him in an abandoned church. He and the Possessed Thunk are both controlled by Eyes. It forces him to attack her, uncharacteristically fast and inelegantly, more like a berserker than the Silver Watchman's ninja-like nature. Robin manages to break him free of possession, and then fight off the Possessed Thunk, destroying it and causing the eyes to scatter.

=Boss Fight: 3 Hearts=

The Possessed Thunk frees the Silver Watchman and starts directly attacking Robin. It is vulnerable only when illuminated by a lamp. One charged Roller Bomb Shot (ie. a missile) can kill it, but this particular boss takes significantly less damage from galvanized Roller Bomb Shots.
