The Mechanical Monstrosity is an boss in Castlevania: Lords of Shadow. A giant scorpion-like mechanical monster created by the mad scientist Friedrich von Frankenstein. It is faced in the Electric Laboratory, when finishing the last part of the level's puzzle. It is later faced again in the Clock Tower, where the fight is much simpler.
The Monstrosity is pretty slow and predictable; anyone who made it this far into the game shouldn't have much problem with it. It attacks with its claws (unblockable) and by shooting lightning bolts. Both attacks are very damaging but easy to avoid. A simple flurry of direct attacks and dodging to the sides when it's about to attack and the beast should go down easily.
After taking out a chunk of its health, the Mechanical Monstrosity will start healing itself using a large lightning machine. Hit the button on the ground with the Black Knight Golem's Dark Gauntlet and the lightning will change color, damaging the boss. Do this a few more times and it will "die".
It returns later in the Clock Tower. Don't worry here, there's a place to refill your magic, so if your health is low, just use Light Magic. Here, the Monstrosity will use a magnetic field to create a barrier of metal objects that he can toss. Simply repeat the same strategy as in the first fight, except here the Monstrosity doesn't recover its health. Its attacks are more powerful and it can be hard to avoid when tossing all objects at once, but beyond that, it ain't much of a problem. When its health has almost run out and the creature is stunned, just grab it for a timed event and the fight will be over.
- The Mechanical Monstrosity seems to be the Lords of Shadow version of The Creature, Frankenstein's abomination. Both use lightning to fight and both were created by a Dr. Frankenstein. Besides, the Monstrosity has a fleshy, baby-like core, showing it is also a partly organic creature.
- The Mechanical Monstrosity bears an uncanny resemblance to the real world whip spider, an arachnid with heavy, spiked pedipalps that it uses to capture prey.
