5D DUDE

From Wefightwiki

5D DUDE is Some Dude who is 5-dimensional. He appeared in the tenth dimension in hope of banishing all of the "wimpy 4-dimensionals" of people and stealing their prized tessaract. After Nobody and MyNameIsKooky got stranded in the tenth dimension, they thought the last thing that they could do before death could be helping the poor 4-dimensional people. Apparently, metal spheres were trapping the people and bringing them to 5D DUDE's lair. After reaching his lair after several ordeals, MyNameIsKooky and Nobody defeated him by teleporting him into eight 4D DUDES and defeating them all, effectively defeating all other antagonists in the dimension as well as using Doctor Heavy to smash the Smashed 10-Dimensional Eggbeater since things from higher dimensions are much tougher. Luckily, MyNameIsKooky's Teleportation leveled up after defeating all the enemies in the dimension, allowing them to free the 4-dimensional people, return their prize tessaract, and escape through a vortex back to their third dimension.
