I decided to make him a Kumos. Thanks for your help guys!
The Keeto seems to be the best choice in my opinion; it's the most violent looking of the three and besides it's absolutely stunning. ❤️

The Keeto is winning! But I just LOVE the Kumos.... gah! D: Now it's between the Kumos and Keeto. The Montre doesn't really fit at all.
Nice pet name! :D I would pick the Kumos.

Thank you! :D This is really hard...
I vote for Kumos.
The scars on his body remind me of violent death.



OMG I JUST HAD A COOL BUT TOTALLY UNORIGINAL IDEA I think I'll make Nex a Kumos. Thanks for your help everyone!
