Today's Fact
He has seized ultimate power more than once — and, as his oldest enemy diagnosed, some part of him always leaves the door open behind it.
The pattern is older than the Gauntlet. With a Cosmic Cube in hand, the godlike Thanos chose to toy with Captain Marvel instead of finishing him — and lost the Cube for it. Chasing the Soul Gems, he needlessly enraged Adam Warlock by destroying Pip the Troll's mind, planting the very warning that undid the scheme. Victory after victory, the Mad Titan kept supplying his enemies with the means of his defeat.
The diagnosis was finally spoken aloud after The Infinity Gauntlet (1991). Thanos had become Eternity, the supreme being of the universe — and still lost the Gauntlet to Nebula in the confusion. Studying the wreckage, Adam Warlock delivered the verdict that reframed every Thanos story before it: on some level the Titan does not believe he deserves supreme power, and so his subconscious quietly engineers its loss.
It is the most dangerous weakness in the universe precisely because Thanos cannot fight it. Armies, gems and gods he can plan for; the saboteur rides inside the planner. Warlock — who knows him, in his own words, better than Thanos knows himself — treated the flaw as a law of nature, and Thanos's career since has kept filing evidence for the prosecution.
Why It's Obscure
Every conqueror fears the hero at the gate. Thanos's recurring saboteur has always worn his own face.
