Forget whatever preconceived notions you may have about heroes and their appearances. Butt Ugly Martians: B.K.M. Battles from Knowledge Adventure proves that looks matter little when you're armed with screaming laser death-rays.

For those unfamiliar with the popular Nickelodeon computer-animated comedy show of the same name, Butt Ugly Martians follows the exploits of three hapless aliens who have been tapped to help conquer Earth for the evil Emperor Bog. Instead, the BUMs take a liking to our primitive planet and decide to make it their new base of operations.

Taken aback by the unexpected insurrection, Bog sends out a new strike force comprising battle robots. It's up to B.Bop-A-Luna, 2-T-Frut-T and Do-Wah Diddy to save the world from butt-ugly domination in nonstop side-scrolling/shooting action.

The seven worlds of four areas apiece range from the bottom of the ocean to the cold depths of outer space. Players may switch among the three BUMs while undertaking these levels. Each BUM can also transform into B.K.M. (Butt Kicking Mode) for full-frontal assault power.
