Background Information

What's special about it?
Frankly nothing, it just is the best rambot.
Where did you get the name?
Surprise: it is my third bot.

Strategy

How does it move?
Ramming, it tries to intercept the opponent by following its own bullets. It reverses direction if it is more beneficial. A small 'wobble' has been introduced inspired by the movement of MaxRisk.
How does it fire?
Iterative circular gun with some protection to avoid shooting straight into the wall. The iteration stops at the outer hull of the opponent. Next to the normal attributes as speed and headingchange, it also takes into account speedchange.
How does it dodge bullets?
It eats bullets for breakfast.
What's next for your robot?
Nothing anymore, as finally it is the highest ranked rambot. This old bot sharpened its teeth.
How competitive is it?
It outranked the best rambot at that time, NanoDeath, in march 2005. In feb 2006, Kev's MaxRisk came along and became the best rambot by a large margin. After more than 10 years a design-flaw was fixed, a clever idea implemented in the gun, and some rather rough movement tweak introduced. Now it is finally the best rambot again.
