Best flipper/lifter: Chaos 2. Why? Though I am not a fan of the bot, no flipper ever terrorized the ranks for as long as Chaos did. It totally transformed robot wars and robotic combat, popularizing the flipper. Even though T-minus, Gravity, Ziggy, Toro, Wheely Big Cheese, and other flipping powerhouses have terrorized robotic combat, none remained as competitive for as long as Chaos 2. Honourable mention: Biohazard
Best pusher: Sewer Snake. Why? The last robot you'd ever expect to be the #1 ranked heavyweight of all time proved that there is no substitute for ingenuity and amazing driving. It breaks nearly all building guidelines used in today's bots, having six big red exposed wheels, no destructive or powerful weaponry, or any flashy, showy bodywork. No, Sewer Snake is all push. A totally dominating force, not even Supermegabyte or Ziggy can stand in it's way. Honourable mention: Tornado
