DC's Bombshells comicbook was allowed to play around with continuity, taking whatever parts had worked about the characters at any point in their entire history. That's how it worked out that this world's version of Power Girl wasn't Superman's cousin from another reality, wasn't the granddaughter of an Atlantean magician, she wasn't any of that. She was instead, like the DCAU Power Girl, the result of a government agency cloning Kara so they could have a Kryptonian they could control. (Don't worry, things turned out much better for this incarnation.)
Bombshells Power Girl was sort of a general "bathing beauty" type pin-up, wearing what was essentially a modest bikini; although the suit as we recognize it today wasn't released until 1946, named after the publicity surrounding America's nuclear bomb tests at Bikini Atoll (itself a German corruption of the original local name "Pik-in-ni," meaning "covered in coconuts"), two-piece garments for athletic activity or even casual wear go back thousands of years.
Power Girl was also one of the few Bombshells designs to feature two characters: she's depicted in the art in in her statue lifting Superman easily on her shoulder, making him look like he's flying and identifying her as a circus strongwoman act. The Lil Bombshell is just her alone, standing with her hands on her hips, but she keeps the short blonde hair and the red kerchief tied around it. To adapt her usual costume, she has blue wraps around her wrists and forearms, wears blue boots, and has a blue belt with a golden buckle.
Series 3 did not get any repaints like Series 1 did and Series 2 was planned to, but there were solid silver chase figures of all 10 new characters.
Covered in coconuts... you know what that still works thematically.
She's got a lovely bunch of coconuts.
