Harley Davidson was the potty-mouthed and very talkative member of the Dark Guard
. Among her other exploits, Motormouth was on hand when the Hulk
visited England in his pursuit of the maniacal Madman
who temporarily took the Prince of Wales hostage. She and her partner, Killpower
, helped to save the Prince just before she used her hyper-sonic scream to blast Madman all the way to the Thames River.
