>>104557634The Doctor and Doctor Doom team up to save the Earth (or as in Doom's case, to save Latveria and by extension the rest of the planet while biding his time to betray the Doctor and steal his technology because of course Doom would betray him.)
Now, the set and tone of the story depends of which Doctor is the one who teams up with Doom. One and Three would keep his eye on him, Two, Four and Seven would drive him nuts, Six would make Doom himself feel threatened, Five, Ten and Eleven would play dumb and foil Doom's backstabbing with a smile, and Nine, War and Twelve would keep Doom on a tight leash and have no room for jokes- I can imagine Twelve hitting Doom with his shoe every time the dictator starts a villian monologue, War just giving him an icy glare now and then and Nine managing to destroy all of his weapons while suggesting him to plant bananas there.
Fuck Eight, by the way.
