Child with chainsaw

Child with chainsaw is from my favorite puzzle game "Catherine". It is a huge, nightmarish, half metal baby. It has a horrifying cry and kills you in one hit. I give this monster 8 out of 10 Tentacles

Mamiya

Mamiya is from the  Japanese only Nintendo game "Sweet Home". After her child fell into the mansion's furnace and burned to death, Mamiya went insane, and kidnapped other children and threw them in the furnace so her child would have "playmates" in the next life before committing suicide. She came back as a ghost to haunt the mansion. She has two forms in the game. I give this monster 7 out of 10 Tentacles

Gatherer

Gather is from the video game Amnesia Dark Descent. They're grotesque malformed humans that can not be killed. You have to run and hide. They're very creepy looking and because of this I give this monster  5 out of 10 Tentacles

Biggy Man

Biggy Man is a monster in the Splatterhouse franchise. He appears as a mutated human with chainsaws attached to his arm stumps and a burlap sack covering his face. In 2010 Splatterhouse Biggy Man lords over the Meat Factory in a gruesome, post-apocalyptic New York City set thirteen months after Rick failed to stop Dr. West from sacrificing Jenny. According to Dr. West, the Biggy Man is a servant creature to The Corrupted. He also says that it has a primative, but cunning intelligence. In fact, Dr. West was lead into a Biggy Man trap once. Another example of the Biggy Man's intelligence is that it actually named itself. When Rick and the Biggy Man finally meet, the Terror Mask comments on how he actually recognizes Biggy Man, and how the two are "screwed". Rick first fights off Biggy Man with a shotgun, knocking the Biggy Man onto his back. The lights go out for a brief second and Biggy Man disappears, and causes Rick to crash down to the bottom floor, where the Biggy Man becomes much more of a challenge. I give Biggy Man 7 out of 10 Tentacles

Monster Party

This is the last boss from the Nintendo game Monster Party. This game is one of the best games on the old school  Nintendo. It has lots of fabulous monsters. The last boss does not have a name I could find. I give this monster 3 out of 10 Tentacles.

Wendy

Wendy is a monster from one of my personal favorite video games, Nier. It is most likely named after Wendy from Peter Pan. It's appearance is that of a huge stone sphere with shadowy, smokey energy,  with a single eye, surrounded by Shade tentacles that can fold together, giving it the look of a closed lotus flower. It is fought in the Aerie, where it causes the majority of the villagers to become Shades. After Nier kills many of them, Wendy emerges from a black swirl in the air and attacks. I give Wendy 9 out of 10 Tentacles.

Leechmonger

Leechmonger is from the game Demon's Souls. As you could guess it is made of millions of leeches. It regenerates health, but is weak against fire. I give this monster  8 out of 10 Tentacles.
