Troy Barrett

Troy Barrett is Betty's best brother, who becomes the newest Galactic Guardian, Atomic Troy. He's also the tallest young brother who's handsome, but powerful than ever before. He will be voiced by Matthew Isen, Tajja's family member, and first appeared in Season 4 and Atomic Betty: The Animated Movie.

Origins
While surviving on Earth with Betty, Troy has brown hair and wears a white tank top, a blue denim jacket, as well as blue jeans and orange sneakers.

When on a mission for action as Atomic Troy, he wears a standard Galactic Guardian uniform, which consists of his white headdress, green battle suit, white gloves, green bracelet, white belt with a nuclear symbol, and white boots, similar to Betty's own Galactic Guardian outfit.

His new bracelet, which can be identical to Betty's jewelry-type weapon itself, is also green and matches his battle uniform. It also has brand new gizmos that Atomic Troy uses to defeat enemies, especially the same laser as her own one.

Prior to its third (and final) season subtitled "Mission: Earth", she and Troy become themselves as Galactic Guardians, while battling against a formidable foe (including Maximus I.Q.), despite mutant enemies invading Earth in all of Moose Jaw Heights.

Personality
He also becomes a real, talented DJ with Betty's best friend, Noah.

Trivia

 * Similar to the teen DJ one himself, Jax Gardner, the character that Troy's voice actor played on Backstage, he decides to use his drum machine while composing dance techno with him alongside the Osborne Twins, using a bass line synthesizer.
 * As for Paloma (from Season 2), she uses a Sylenth-like synthesizer with them, while Betty sings a special techno hit, "Atomic Power Girl".
