[DC] Can Beast Boy turn into hybrid beings?

Can he transform into, e.g. a liger? What about alien hybrids, like a Kryptonian-Martian?

Yes. If it exists, and if it's an animal, he can transform into it. That said, it probably needs to be a creature that he knows exists (or once existed). He can't just make up theoretical hybrids and transform into them. So if a Kryptonian-Martian hybrid does exist out there, and Garfield is aware of them, he'll be able to take their form.
