What we do know is that the All-Stars (seemingly in its entirety) was the first competition to be filmed, as the pit release is noticeably absent. This also explains why Dominator II and X-Terminator (and most importantly Pussycat) all look different. It also gives reasoning behind Behemoth being the Challenge Belt holder, after it beat Hypno-Disc and deserved to beat Razer before being awarded the belt.
