When all the robot builders leave the pits to come to see NightWing fight, you know you're in for a good show!

Nightwing: It somehow manages to keep mobility with no working wheels, I need to have a special attachment for all of my robots to fight it, and I'm sure it's given someone hearing damage when it does its signature dance on the arena floor. I love it, keep bringing it back.

I've been fighting against this robot for quite a few years now, and I'm always impressed and amazed at how resilient and reliable it is. It is also extremely entertaining to watch due to the gyro forces from the huge weapon.
