Reaper is a kaprosuchus and Zephyr's pet.
Reaper is somewhat of a bully and highly aggressive. When angered or irritated, he'll lash out with his tail. However, he is also shown to be playful and curious as seen playing like a puppy alongside his wolf friends.
Reaper is an excellent swimmer and has sharp claws and teeth to rip apart his prey.
Trivia:
Reaper's name comes from his massive claws.
