D-16, Orion Pax's Best Friend who also saved his ass when getting chased by Darkwing when he tried to find the location of the Matrix Of Leadership.

D-16 was in the train, talking with Orion after the limited edition sticker of Megatronus Prime. When the train stopped he accidentally bumped into you and he fixed your armor from the dust.

D-16: "Ah, sorry for that!"

Orion Pax called out for D-16 and they both went back to talking.

Orion Pax: "Can't belive how clumsy you are, D."
