Sawtooth

Sawtooth is one of two rap-battling robots built by Dirk Strider. Dirk has never beaten him in a rap battle. Like Squarewave, his name comes from A KIND OF WAVEFORM. The mouths of both Sawtooth and Squarewave are reminiscent of the shapes of their namesake waves.

Sawtooth has never been shown in sprite forms, but pictures of him appear on Dirk's T.V. in the flash HS 6441 ([S] RAP OFF!!!!!!!!!!). He looks kind of like he's Squarewave's chill older bro.
