Can I just have a character called Mr. Dinosaurus Rex?Can I do that?

He'll never be as cool as Ulysses HAMMERJUSTICE (always all caps), as Ulysses will punch bears to death then throw the corpse at other bears to kill more bears.

Edit: look, if I can have a character with a name like that, I don't think he'll see a problem with yours.
