Another original character with familiar powers... although there's never been an actual Ant-Girl in Marvel Comics. Her name is Samantha Peters, and as I stated in a review below, she's an OCA1A albino. That's why she's paler than a Goth's ass. She's got the natural ability to grow to any height up to 60 feet tall, and is later augmented to match Kaida in being able to shrink to any size down to half an inch. She's also the host to the second generation of Ant-Man technology, which is a combination of antannae that extend directly from her head and electronics sewn into her costume. The costume covers everything but her face to minimize sun exposure, and contains goggles to protect her fragile eyes at all sizes.
