Key: DSMMA - Dr. Strange, Master of the Mystic Arts

Defeats the clone versions of the Hulk and Namor found within the Dimension of Unreality with a single blast - DSMMA 2

Strange faces Death amidst the cosmos itself, where even the slightest touch of a meteorite means certain death. Death hurls the elements of the cosmos itself against Strange- swarms of meteors, flaming planetary spheres, and even warps the ether itself around Strange. Strange eventually comes to terms with Death itself, and unites with Eternity, assuming the place of his form /avatar and overcoming Death itself. In doing this, he passes a trial that frees him from the passage of age, symbolized by the Ankh of Everlasting Life on his forehead - DSMMA 4

Survives being imprisoned in a sphere of nuclear flame - DSMMA 27

Forces a living star to go Supernova (which he survives being in the presence of, both astrally and physically, multi-tasking to boot!), and after detonating collapse into a black hole. He then manipulates it, rendering its gravitational pull null for a short time, before hurling it into the Wheel of Change - DSMMA 27

Survives the In-Betweener's assault on him, where Strange was trapped within entire levels of reality (which the In-Betweener states can extend to even fantasy), and later subject to very high-level reality warping (with the In-Betweener sending Strange to the ends of Infinity, backwards in time to be burned at the stake, bound for all time on any billion alien worlds, etc). He also endures the ensuing mental insanity - DSMMA 28

Note: The In-Betweener is an abstract and creator of the Wheel of Change. He/it embodies the concept of Dichotomy, much like Sire Hate embodies Hate, Anomaly embodies things which are not things, etc.

Strange breaks free and calls upon Lord Chaos and Master Order, the abstracts of Chaos and Order, themselves, throwing that same power alongside his magic at the In-Betweener, besting him and imprisoning him - DSMMA 28

Channels his mystic powers into altering the pitch of the True Wheel of Change, which is capable of effecting universal change and destruction. Strange succeeds in changing its direction, causing the universe to turn in on itself and be restored - DSMMA 28
