Minecraft Dungeons:Obsidian Monstrosity

The "Obsidian Monstrosity" is the name given to a statue found in the Obsidian Pinnacle. (not a boss fight)

Note: the part of the level containing the statue 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 mob 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 Left 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.
 * Upon closer inspection, these cracks are fully animated.
 * Because of the obsidian surrounding them, they bear a slight resemblance to Crying Obsidian.
 * It's oversized head (not including the horns) is 64x56x36, the largest head in Minecraft series (not counting the Wither Storm in Minecraft Story Mode as this one is not 'canon' according to Mojang).
 * Many believe this mob will be a boss in the Nether DLC, due to the fact its made of crying obsidian, has nether portal cracks, and that there is a giant nether portal behind it though there has never been any proof nor confirmation by any Mojang employee or the devs.
 * Because the mob is more then 2 times taller then the Redstone Monstrosity, the HP has to be at least 5 to 4 times larger.
 * The body parts of the Obsidian Monstrosity is some kind of a Redstone Golem and Redstone Monstrosity Hybrid.
