Minecraft Dungeons:Obsidian Monstrosity

The "Obsidian Monstrosity" is the name given to a unimplemented mob found in the Obsidian Pinnacle.

Note: the part of the level containing the mob does not always generate.

It can be found under construction in one of the variants of the part of the level that generates the second main Redstone Golem fight. The Obsidian Monstrosity is its name in the game files, as it is not referenced in the base game. It seems to be a variant of the Redstone Monstrosity, but is larger.

Appearance
The Obsidian Monstrosity is a colossal, largely unfinished mechanical golem found in the Obsidian Pinnacle. Unlike the Redstone Monstrosity, it is significantly larger and is possibly powered by blocks similar to crying obsidian, found around its body. Its body also possesses more cracks unlike its redstone counterpart, and bears golden outlines and intricate square designs and layouts on its feet and its front body, it also possesses four eyes and three fingers resembling the block its being powered with. Noticeably, it lacks a right arm, possibly still being made.

Trivia

 * The Obsidian Monstrosity looks similar to concept art for the Redstone Monstrosity.
 * The cracks on the outside of the Obsidian Monstrosity, instead of being made of redstone like the Redstone Monstrosity, seem to be made of the Nether Portal block.
 * Because of the obsidian surrounding them, they bear a slight resemblance to Crying Obsidian.
 * The size of this Monstrosity is similar to that of the Giant Magma Golem from Minecraft Story Mode Season 2 Episode 4 Below the Bedrock, however unlike the Giant Magma Golem which is taller than it is long, for the Obsidian Monstrosity, it is longer than it is tall, but still noticeably larger than the Redstone Monstrosity
