Trapped in Reverse Dimension


Dopples, Shadowreavers, Dimension X

First Appearance

The Fury of CandyCao7

OiramOiram12345 is MarioMario54321's Doppleganger. He first made a cameo appearance in The Fury of CandyCao7. He then appeared in OO12345 and the Shadowreavers as the main antagonist. He appeared in other videos of MM54321. His final appearance was OO12345 and the DSX, as the true main antagonist where he called himself the master of the dopplegangers and the master of the Dark Star X. He merged with it and the Dark Star, first to become Dark Bowser X along with Bowser X, then OiramOiram12345 X, but was defeated and was sealed in the Reverse Dimension.

He is one of the most powerful antagonists ever known to appear in a MarioMario54321 series, from causing massive chaos through dimensions to attempting to convert Mario's world into the Dark Star X's. He was thought to be the original creator of the doppleganger project, but it was soon revealed to be Dark Star X's creation.       

He managed to escape the Reverse Dimension with the Dark Star X. However, the DSX was classfied as a reverse counterpart, so the Light Star X was created. OO12345 decided to travel back in time to 12 billion years ago and fuse the two to create Star X in the trajectory of a comet.
