A/N: which one of these forms of bowser was the strongest.

Dry Bowser.

Shiny Bowser.

Shiny Robobowser (it's a fusion of the bowser from paper mario and the bowser from the mario and Luigi games).

Black Bowser.

Giga Bowser.

Dreamy Bowser.

Austin: my thoughts are between Dreamy Bowser and Giga Bowser.
