Viaton

Viaton
Viaton is a human-like biological creation, made by King Certicus and Blank-X. He's been a long lasting villain in the MUTK/LUTK Invasion series. Albeit he was mostly a minor villain, as much as he had appeared. It's to be assumed that the events of EU:NG seasons 2-3 had happened. So, he had met and served Universia during that time. Although, his creators were King Ceritcus and Blank-X. Strangely, Viaton has not showed off his ability to absorb people's powers very much. Even though, he should very well have this ability. The only person he's used it on is Liigii.

MUTK Invasion Season 2
Viaton makes his firs appearance challenging the heroes to fight during the fight with Sqeegee. He was so strong to the point of where Malleo transformed to fight him. Even for Galaxion, and Photohon to consider fusing. The fight continues mostly off screen, until Viaton shows Ultra Rage. The fight between him and the heroes heats up, until eventually the heroes sense Mutk, and goes to fight him instead. Leaving, Viaton alone to himself.

LUTK Invasion
Viaton later returns in LUTK Invasion, where he interrupts the fight between the heroes and Liigii. By nearly killing Liigii in his Buffed form (Hinting he may've absorbed someone's power offscreen). During his rematch with the heroes, it was clear he gotten a lot stronger. As when Zamon transformed, he didn't do much damage to Viaton. Eventually, it got to the point where ????????, Ditto, and Awesome Face travel back in time to get back Rolox for help. But when they came back, Viaton was easily overpowering all of the heroes. Eventually, Jupitais attempted to defeat Viaton with a very large blast, but it had little effect on Viaton. Rotu-4 used an upgraded version of Ultra Rage, and began overpowering Viaton a little bit, but this only made Viaton himself use Ultra Rage to fight back. In the end, Senz interrupted the fight and Viaton presumably retreated. Later, Viaton spectated most of the fight with Sqeegee and commented on how it was getting good. Until Glace and Aster challenged him to fight, with Jupitais joining them. He then teleported with them to a different location to fight. The entire fight was offscreen, but it showed that Glace, Aster, and Jupitais easily defeated Viaton. To the point of where Viaton lost his buff form. Seventy five then arrived, and blasted Viaton into a different location. At the moment, Viaton is alive and is currently fighting in the Infinity War.
