Tentacleman

Tentacleman is the ruler of the Void and the leader of the Slenderman species.

Alive
His body is different than the rest of the Slenderman species. He has a blocky body, and real tentacles on his back. All of the other Slendermen have realistic looking bodies and artificial tentacles.

Alive (Infinity Tentacleman)
He has a realistic looking body. His torso and right leg is red. His head, arms, and left leg is white (not that white, human white). He also has a tie.

Dead (Ghost/Soul)
He looks like a regular Slenderman, except he is more realistic and ghost-like. There's also light coming out of him.

Before the Series
During the creation of the ROBLOX universe (Year 0), Tentacleman has been created from the many amounts of dark matter and void matter in the ROBLOX universe. Those amounts of matter also created the Void. They also created the Slenderman species. Tentacleman is the ruler of them since he was created first, and has been the ruler ever since.

New Korblox (SPOILERS: Read the whole series first before reading!)
Tentacleman was talking to a Slenderman about failing to get the next victim. He said that he'll do it himself. Korblox transformed back into his normal form, but it was right in front of Tentacleman. He was about to kill Korblox, but Korblox ripped a tentacle part of him. Tentacleman was so mad that he turned into Infinity Tentacleman, a form that is much, much stronger than his normal form and only used when necessary. He summoned a Slenderman. He was about to kill Korblox now that the Slenderman pinned Korblox down with telekinesis. But then, Destructias (as a dominus: flew here after the three explosions) killed the Slenderman and even Infinity Tentacleman! But as a last resort, his soul appeared and tried to chase and kill them. Korblox and Destructias entered the portal back to the baseplate before they got killed.

Currently
Tentacleman (even though he is just a soul now) is still the ruler of the Slenderman species and he will be until (probably) the end of the ROBLOX universe.
