Giygas

Giygas or Giegue is of an unnamed race in the video games Mother and Earthbound created by Shigesto Itoi and published by Nintendo in 1989. He was raised as a good soul by the abducted couple named Maria and George in the year 1900. George, against the people's wishes, learned the powerful PSI (PK) powers. The race had told Giygas it was unacceptable and he must destroy the Earth with his army of Cyborgs called Starmen. He was defeated by a young boy named Ninten 80 years later by singing a lullaby called the eight melodies that Maria used to sing to Giygas. A few years later, he went insane with power after he found a lonely fat boy named Porky Minch. He was so unstable he had to be kept in a capsule called 'The Devil Machine'. Later, a boy named Ness and his friends killed Giygas with prayers and another set of melodies. He lost all of his mind in that form and had no idea what he was doing. When defeated he is never heard from again and Porky escapes via time travel and wrecks havoc in the future. Some fans say Giygas isn't as evil more than he was manipulated. His powers included PSI Freeze, PSI Rockin and "ungraspable attacks" as well as combined PSI powers. Of his Starman army there are many types such as Starman, Starman Junior, Starman Super, Blue Starman, Ghost of Starman, Starman Deluxe, Last Starman, and Final Starman. He can create poltergeists and can take control of animals.

The None's character
The alien as a custom fighter for M.U.G.E.N. by The_None was created to be disturbing/horrifying filled with memes and various things not in the Mother series. Aside from his PSI attacks, the character sucked in it's encroaching darkness, or grabbed by hand temporarily vanishes and bites the character causing it to turn into a sliced up human if killed. It can also spawn headcrabs from Half-Life, even if it's not facing him; when spawned, the creatures remain until either the player is K.O.'d, or if it's attacked. It also has abilities to create portals, sending victim to random death traps where he/she must escape before dying, in gorey fashion which then it's soul leads to the darkness. It's mind generated traps include the fryer in Belgrave Square Labs where the player must quickly press the horizontal keys even when a victim is heating up, then and after it's health bar reaches to zero, the glass shatters with a beeping heart left on the floor, and a blade mine pit with vampire-like statues, and sharp blades, chainsaws, and a saw that cuts a victim into a skinned human, in here the player must press the correct buttons three times before getting skinned completely; both from Eternal Champions: Challenges from the Dark Side; more challenging traps include the forest from Doom where it must shootout every monster, Hol Horse shoots the shooter leaving a broken glass on the screen becoming stunned which then it meets it's death. Shooting a Slender Man will automatically K.O. the shooter after getting faced up, then automatically K.O'd. A room with Hisui's are filled with faceless variants that should be avoided and the one with the face hit frees the victim, an Ao Oni in the dark closet attacks if not successfully prevented, and the volleyball drops to be kicked to the top before being chomped when it reaches the ground. In addition to it's mind controlling ability, a random image pops up, or showing a player dying rarely displaying a fake K.O..
