|~ SPD Orange Ranger|
Boom is a former cadet who flunked out of the Academy after only a few days and currently serves as Kat's assistant and Chief Gadget Tester. He dreams of being a Power Ranger, and had a fantasy of being an orange-garbed member of S.P.D.
School Drop Out
Boom never told his parents about being kicked out of the academy due to his incompetence. He managed to convince them that he was the "Orange Ranger", which came back to haunt him when they came to visit. He was forced to don a mock-up costume and team up with the B-Squad, putting the true Rangers in trouble. He then returned to what he knew best, and finally told his parents about his real job: guinea pig for Kat's inventions.
Boom showed his courage at the end of the Troobian-SPD conflict. He was with Kat when Broodwing and his forces attacked Delta Base, sending hundreds of Krybots to fight the SPD cadets. Broodwing soon caught up with Boom and Kat and trapped them, but Boom summoned R.I.C. who set them free. Later, after Broodwing was defeated, Omni arrived, sending his own army of Krybots to Earth. Boom helped inspire the cadets to stay and fight, saying that even if they all left, he'd stay for the B-Squad who were captured by Emperor Gruumm. And so, Boom fought alongside Kat and Sa against the Krybots and helps hold them off until reinforcements arrive in the form of the Nova Ranger from the future and troops from headquarters including Commander Birdie and Sergeant Silverback. With their help, the Krybot forces are destroyed. The Power Rangers later returned and destroyed Omni and as they were celebrating the return of Cruger and his wife Isinia, Gruumm returned and Boom watched the two quickly battle it out before Cruger emerged victorious.
