Thanos has neither the power, nor the versatility, to deal with every one of the characters listed in these "trials".
He wouldn't even be able to deal with Flash alone, without the IG. Throw in Martian Manhunter, Wonder Woman, etc, etc, etc? He'd get lol-stomped.
Honestly, Thanos has literally no chance at clearing any of these trials. I can't see the second pic, but if it's a feat of SBP's, there is no way Thanos w/out the IG is replicating it.
Hell, most of the mainstream versions of Superman are well above Thanos. Superboy Prime is literally in a realm above even those Superman incarnations, to the point where he's able to hopelessly outclass them in terms of speed, strength, durability, etc, and has managed to kill dozens upon dozens of them, along with hundreds of Green Lanterns, etc.
Every time SBP is in a comic, he's literally fighting everyone at once, and winning. The only way he's ever dealt with is by PIS, like a Guardian warping him to another dimension, being caught in the Speed Force by almost all the Speedsters, etc.
Imagine if Thanos was in place of SBP during the events of Infinite crisis- he'd literally get manhandled in minutes, by the combination of the JLA, JSA, Teen Titans, GLC, etc. Hell, Superman alone would have a piece of Thanos, and he's not even the strongest contender here, let alone up to par with SBP.
