This is Aaro who is a morph
a morph is someone you can turn in to an animal at will because of this they are used in the military for finding stuff but Aaro hated doing this so he ran off and started helping scientists find new species.
When aaro turns human all he has on is his pants because he cut his shirt. So DG8 carries extra shirts in his tails
Aaro is the handler of CT9 and DG8 who are robot dogs and cats
