To clarify, I feel Chaos 2 had a near-terrible performance in Series 6. Yes, it managed to flip Iron Awe out of the arena, yes, it got a solid flip out of Dantomkia, but at the same time it flipped itself over against Destructosaur, lost the use of its flipper after beating it and Iron Awe, barely survived against Crushtacean and ultimately, Dantomkia's victory over it was largely through a massive screw-up on Chaos' part.

TL;DR - Chaos 2 is better than Vader, but performed worse overall, especially as a heat finalist.
