Mecha-Bowser

Mecha Bowser (also known as Robo-Bowser or the Bowser-Bot to fans) is a huge robot that looks like King Bowser.

In Paper Mario, Mecha Bowser goes by the name Bowser???, and is controlled by the Koopa Bros.

The 2.0 version of Mecha-Bowser was controlled by Bowser Jr. in Super Mario Sunshine. This version of Mecha Bowser was much more advanced. The second version also appeared in Mario Power Tennis.

Tattle: Bowser...? But he looks kind of...lame. I mean, he's lame anyway, but... Does Bowser really look like this? I always imagined him looking, well, a lot scarier.
