(If it suits you, you can take one of the nouns and stick it to another, the possibilities of combinations are also neat.)

Don't know the way he is able to manipulate the animals (Telepathic or Whispers of some kind), + l don't know what name you are looking for [example: Dr ... , or lets say (Animal) - Man]. The only one that l can come up for now is "Dr Zoic". Try to make him as cool as possible.

Anything related to animals or nature. Bestial, Adam(as in Adam and Eve), etc

Well the name has to relate to animals, and what he does,

Beast master? seems to simple,

King of the beasts? idk
