Good one. "Angels! Immediate launch!"
The show was Captain Scarlet, starring a literally unkillable hero. Was my favorite when I was real little. Exceptionally violent for a kids show, it totally warped my fragile little mind.
The angels were: Harmony, Symphony, Melody, Rhapsody and Destiny.
Real names: Chan Kwan, Karen Waiwright, Magnolia Jones, Dianne Simms, and Juliette Pontoin.
(I actually remembered the musical themed ones, but I had to Google-cheat to get Destiny and the real names..)
