Returner

Returner (real name "*") is a dangerous AU Mugen. Returner is a Mugen very similar to Real Mugen who has seemingly undergone a process known as Ascension - a ritual that turns one into a ghost-like spirit. After his awakening, he became even more powerful, now possessing the ability to assimilate any Mugen in the multiverse who becomes vulnerable to him. He is often represented by a playing card, the King of Diamonds, which was found to resonate with most Mugens.

Appearance
Returner's original appearance seems to be that of an inverted monochrome Real Mugen. He is often seen grinning creepily. Whenever Returner assimilates another Mugen, that Mugen's color scheme will be changed to look similar to Returner as well.

Biography
Returner's origins are unknown. He seems to have existed since long before most Mugens in the multiverse. He first made himself known when he assimilated Real Mugen after Real Mugen had been missing from the Internet Detectives. Returner went on a power-hungry rampage using Real Mugen's body during this time. It wasn't until the Internet Detectives banded together with the Spanish Army that they were able to finally defeat Returner, purging him from Mugen's body. This event would later become known as the Jordi Wars. Though Returner may no longer dwell within Real Mugen, he still exists all across the multiverse, possessing weak-willed Mugens in an attempt to gain more power.
