How does Thanos absorbing just the Multiverse, say "there are other Cosmics Outside the Multiverse?"
The way it should read is, Thanos only absorbed the Multiverse, because that's where all the threat remained.
Now that I think about it, there are powers that could careless about Thanos and his Multiverse, but Other Universes with in the Multiverses have a great reason to pose a threat to Thanos.
Seeing his domination of the 616 Reality, they would see Thanos as a potential would-be conquerer of other Realities, namely their own.
A conqueror only grows more powerful by winning more land. As with emporers. Thanos would get stronger, the more realities came under his boot heal. If he did rule one multiverse, ( which I'm almost certain he didn't, but I dont' doubt that he could given that he so easily pwned the LT), then he would know that there were other stronger multiverses out there. he is a conqueror and would get bored. with an infinite omniverse, he could just keep meeting greater and greater challenges.
