The bio-chemist is a character that appears in the Sonic the Comic series published by Fleetway Editions. An anthropomorphic young female cat, she developed a growth formula to instantly re-grow trees that had been cut down for Christmas.
The bio-chemist wears red cat's-eye glasses and a white lab coat over a blue shirt, black tie, red skirt and blue ballet flat shoes.
The bio-chemist demonstrated her formula to Tails by re-growing an entire tree from a mere stump. However, when Robotnik sent Badniks after the formula, the tank smashed and the formula splashed Tails. Although the bio-chemist initially claimed that the formula wouldn't affect him, she was soon proven incorrect when Tails grew to a gigantic size. This caused him some problems until the formula was washed off by rain and he returned to normal. Unfortunately, the re-grown tree was also reverted to its previous state after getting caught in the rain, and the bio-chemist realised that her formula was a "wash-out".
