FUNCTION: Messenger
"Stay in my way and you'll end up on the floor."

If you see a small blue streak run past or at you chances are that it is Trihorn. He spends much of his time running from place to place seeing what's new or sending messages. Trihorn has been known to go through the messages he's delivering on the odd occasion. When he meets someone he doesn't like he will usually ram into them and try to knock them to the ground, but usually isn't able to do so due to his small size. If he is in an open area he will most likely chase after others. Trihorn is the animal partner to Powerplay. He transforms from a blue and grey triceratops into a cassette. Trihorn was onboard Atlas when Diablo was also onboard briefly while searching for Hellfire. Hearing that Powerplay was with LONAC, Trihorn decided that he would join aswell so he could be with him again.

In cassette mode, Trihorn is able to store a near infinite amount of data due to his internal-light matrix data store system like the other cassettes have. In triceratops mode, Trihorn is armed with 2 combined light blaster and missile packs. He tends to just run into his enemies with his horns rather than firing his blasters at them.
