Halley

"Ah! Halley! She's beautiful... and bucktoothed. My friend knows that Halley's comet would appear on the naked eye from Earth every almost 80 years. Thanks to her, this girl is as cute as she is, even when she was born on a comet. Coincidence?"

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

Halley is a rabbit who has a cheerful and fun-loving personality. She loves playing with Comet and Radar and loves the game of Quasmo-Digi Soccer (sometimes known to the British Army soldiers stationed in the Astroblast Space Station as Quasmo-Digi Fotball). Halley is also a very good friend, and is yet very close to being best friends with Comet. She gives others rides and makes smoothie deliveries on her surfboard. Furthermore, since Halley is a rabbit, she is likely to have an affectionate personality since all rabbits have natural caring personalities and the natural ability to easily recognize others' emotions where they would comfort and console others when they're feeling bereaved and/or tearfully sad. Dogs like Comet can do the same, but only when one is feeling plainly depressed. For rabbits like Halley, it's a different scenario in times of comfort.

In When the Cold Breeze Blows Away, she serves as a pilot of Team Astroblast, which takes part of the Future Alliance and the Sonic Alliance. Like Sputnik, she is also part of the Preschool Girls as well. She is voiced by Aja Wooldridge in the Korean drama.
