Next Battle:
Son of Ripper (Ill assume that Rippo was a typo)
Nidhogg
Nitro-Gene 4.5
Sir Spinalot

Son of Ripper is one tough guppy, with a spinning bar powered by an E-Tek. (No black hole generators!)

Nidhogg has earned the right to enter the tournament, by destroying Growler in the Gauntlet competition with his mighty crusher.

Nitro-Gene won the right to enter by competing in the Challenge belt. It has a flipper, and is invertible, making it a real problem to stop.

Sir Spinalot is a Tornado Mer-esque robot, with a Revolutionist-shaped body, and a large spinning blade.

Any Tactics?
