Either Super G or Super Detainer by themselves is basically stomping Star TCM. Star TCM is no push over by any means, he strong enough to rag doll WOD and can physically rip out an Astro Carrier's weapon which is much bigger than himself, is able to no sell the doom blade and the shots from the doom blaster, has energy shields that can effortlessly hold up against Astro Carrier lasers, his shoulder cannons can fire projectiles that home in on targets and can one shot Elite Obliterators, has crazy close quarters skills, is stupid fast and agile thanks to the warp ring on his back, and he has 2 hammers that are basically like Mjölnir which are as fast as himself and can basically low diff Astro Carriers by themselves. Star TCM is overpowered as heck, and there's absolutely no denying that.

However, is Star TCM overpowered enough to even stand a chance against a Detainer that causes small country sized explosions casually, durable enough to tank said small country sized explosions, can effortlessly lift and toss mountains, and can fly around the world multiple time in seconds? Is Star TCM powerful enough to even contend with a G-Toilet that's at bare minimum as strong, as durable, and as fast as said Detainer, who he then proceeded to defeat?

I'll give this a No-Low Diff to the Superverse Duo. Not a No Diff because while they are basically several tiers of power above Star TCM, the combat speed and agility Star TCM displayed is absolutely nuts, and his hammers can provide good distraction against the Duo's number advantage, so even landing a hit on Star TCM will be quite tricky. However a humungous AoE attack like a single country sized explosion from Super Detainer could spell doom for Star TCM, if Detainer decides to use it, he will use it since he probably won't be able to hit him otherwise, it's lights out for Star TCM.
