Thanos Dumps Hela
Spoilers from The Mighty Thor # 4 by Jason Aaron and Mike Del Mundo featuring Thanos dumping Hela amidst the war in Niffleheim.
So according to the story, during the falling out between Thanos and Death, the mad titan finds a rebound girl in the form of Hela.
The two had agreed to a partnership to get Hela Niffleheim back under her control.
Unfortunately, Thanos never lifted a finger to ensure that Hela gets her realm back. To complicate things, Surtur’s daughter, Sindr, also invades Niffleheim around the same time the wedding was supposed to take place.
Thanos leaves Hela around the same time Sindr finally reaches Hela.
The conclusion for this arc is rather generic but I like how Aaron wrote it.
