Forum:Biggest Improvement

This is a forum for discussing the biggest improvements in a robot's performance. Obviously Razer from Series 4 to 5, and Tornado from Series 5-6, but I mean some others. In my opinion,

The improvement performed by Bigger Brother. From going out in the second round to defeating reigning champs Chaos 2, Hypno-Disc, the seeded Splinter and 3 Stegs, and the deadly S3. That was a huge improvement.

Any others, state below.  Toon Ganondorf    (t    c)
