With their power combined Alna and Vin are possibly equal to the whales you keep mentioning.

Vinashy could just drain them and steal their powers

Well, not really. The "space whales" only kinda look like that. What they actually are in Worm is multidimensional worm-like "Entities" that go around using entire worlds as petri-dishes for their experiments into how to truly overcome Entropy.

Each Entity is comprised of hundreds of thousands of individually planet-sized "Shards", each one having dominion over a specific power and able to in time spawn offshoots of themselves with new related powers. The shards have no blood and so probably can't be drained. They are more like giant crystalline computers that only [i]seem[/i] flesh-like, and every single one of them is independent from the whole but connected like a hive-mind. Their powers function through the manipulation of dimensional physics and basically hyper-advanced math and computation of physics, and so it's not really conventionally possibly to "steal" their powers. Killing a Shard isn't really going to do anything to an Entity even then. They can easily cast off and/or disconnect themselves from compromised Shards and are more than able to eventually create a replacement later on.

Like, these Entities are capable of destroying entire multiverse clusters in a single blow if they feel like being serious, and they actively do so as a method of propelling themselves across the multiverse using the force of the explosion.

Killing these guys is a big flipping deal, and the only reason canon Worm went so well was that a Third Entity tricked and weakened one of the two that was threatening Earth, allowing it to be assassinated by a human that connected to one of its strongest powers. That left only one full-powered Entity for humanity to have to fight, and they only won even then by making him depressed over his partner's death and causing him to commit suicide. That was the original course of events separate from the AU caused by Collin's interference.
