Comet

"Now there's old Comet. He's the eldest member of the Astroblast Space Station staff members. If I order him a smoothie, that'll be a goddamned great idea. It'll cost me a few of my country's wons I'm holding as of now. Not to mention, this guy's kickass."

--Su Ji-Hoon, Welcome to the Astroblast Space Station

Comet is a dog who wears blue and wags his tail from A Tail of Tails.

In When the Cold Breeze Blows Away, he serves as the leader of Team Astroblast, which takes part of the Future Alliance and the Sonic Alliance. However, he was being bossed around by Miles Callisto and Sonic the Hedgehog. He is voiced by Vinnie Penna (or Wayne Grayson) in the Korean drama.
