Shadow Mario


Bowser Jr., known in Japan as Koopa Jr. (not to be confused with Koopa Kid), is the secondary antagonist of the Mario series, and the youngest child of Bowser and the apparent heir of the Dark Land. He debuted in Super Mario Sunshine. He acts as the main antagonist of both Super Mario Sunshine, and New Super Mario Bros., with his father only playing a minor role in each. He is a playable character in various multiplayer Mario games. Since his debut, he has stolen the spotlight as the main villain from his father in a few Mario games.

Attack Potency: Universe level+ (Not as strong as his father or mentor but hardly far from their power, as official sources frequently states that he's almost as powerful as the former and constantly fights with the Mario Bros.) | Multi-Universe level (Shadow Mario polluted and cursed the entirety of Isle Delfino. He also has an amazing amount of knowledge on the Secret Levels, somehow knowing when Mario enters them and where they are all located. There are also cartoony designs within these universes [there being 10 of them in totality, possibly more, with four matching the standards and the others scaling] like the train tracks, which provides more evidence Shadow Mario created them. Not to mention the fact that his goop is flowing directly from a Secret Level here, proving his association with them. Because their celestial bodies match ours [Not to mention how those stars are different colors and luminosisties, showing clearly that the Doppler Effect is in effect, making those levels expand infinitely—just like our universe. And this is without mentioning that another one of the Secret Levels has enormous clouds out in its space, which is identical to our universe's clouds in space that form galaxies over time. Clearly these are universes, and the infinite voids back it up] and because it's seemingly an infinite void, these are full-blown universes that Shadow Mario created. From scratch, mind you; meaning he also created their space-time continuums. We know he did so in a matter of seconds because there was a live commercial at the start of the game that shows everything hadn't been screwed up yet, and Shadow Mario was in the background, seemingly just arriving. And Mario was literally just about to arrive, meaning that Shadow Mario, somehow, corrupted the entire island and created these levels in a matter of seconds to minutes.
