Although Habib is technically the most powerful, so you get a pass. Or rather, Swift. Even lacking feats as the new embodiment of the Doctor, she inherits their experience. And with at least a modicum of superhuman speed and durability, she's moderately less prone to speedblitzes and such.
Also, "Strongest version" of Thanos is technically the recent unkillable version. If the Cosmic Cube couldn't do jack, neither can pretty much anything else.
If you use a powerful-yet-killable Thanos, this is actually an interesting contest.
Are you talking about when the low powered cosmic cube put him to sleep, or what incident are you talking about exactly?
