Damn, that was fun! I played it with both the Aggressive Robots SOC and the Hellbound Battle 2 SOC. Playing this on Very Hard would be NIGHTMARISH if not impossible(Probably possible in Co-Op). You'd have to dodge like some kind of crazy monster and trick him into hurting himself sometimes(I managed to get him to mash himself with Detons once or twice in Hellzone 2, and in Hellzone 3 I think he stabbed himself on a spike because I was busy dodging when he took his last hit, not hitting him)
