[DC] Could Beast Boy turn into Doomsday? What is the strongest creature he could theoretically turn into?

I noticed beast boy doesn't really have any limits to his power that are clear cut. They say it takes effort for him to change into creatures rapidly, but that is about it. What is stopping him from turning into doomsday if he wanted to? What would be the strongest creature he could turn into?

Beast Boy's power is fueled by the Red, the lifeforce connecting all animals. Every planet with animal life has a Red, but they're not interconnected. As long as BB is on Earth, he can only turn into animals native to Earth. For him to turn into Doomsday, he'd have to be on Krypton, which is gone.

Also, it's debatable if Doomsday is connected to the Red at all, since he's an artificial creature.
