He eats more then blood. Energy, powers, spacial authority, and traps the soul in his scythe.

That still wouldn't steal their powers. That's not how the Entities work. It's not special energy. It's literally just ascended math. Unless he has the mental computation power and absorbs their knowledge of physics, it's useless to him.

Also, the Entities don't actually fight using their real bodies. They channel powers through humanoid avatars and hide behind dimensional barriers with their body scattered out across multiple dimensions. Getting at their souls -if these abominations even have one- would require reaching their true body parts... many [i]many[/i] times, since they can shift dimensions at will. As I mentioned, each individual Shard would effectively be a separate soul of a massive hivemind. These things are the furthest thing from easy to so much as challenge, never mind kill.

And this is assuming one can get around their Path To Victory power that literally gives them the precognitive step-by-step path to perfect victory in literally any situation. The only limits are that it's naturally hyper energy intensive to use, so they save it as a last resort for foes they have to take seriously.
