Serilda's parents were the German heroes, Golden Bear and The Carpenter, both members of the Uber Force in the 1970s and 1980s, and so she has always been comfortable around uberhumans. As a second generation German hero, Serilda is on the obnoxious side and seems to think she is some kind of uberhuman royalty, although the public seems to enjoy the role.

Outside of her superhuman career, Serilda is a PhD student in Microbiology, and works at the Institute of Microbiology and Hygiene in Berlin. She has only recently joined the team, and has managed to bring a series of weird coincidences with her, one of which nearly burned down their headquarters.

Serilda's mother, Golden Bear, divorced her father who turned out to be a Russian spy, and later remarried Bernard Schaefer. Serilda's step-brother, Hansl, is also the superhero Zeitgeist and they both currently serve on the team.

Serilda is a spoilt brat who enjoys the attention on her whether it is in her public or private life. Possibly as a result of being a second generation uberhuman, Serilda is a little weird in that weird things seem to happen wherever she is. She seems completely ignorant of the phenomenon although her team mates are growing concerned - mostly for their own safety.

"Cosmic waves are up, and you're going down!"

Schmetterling, which means Butterfly in German, is a name she gained early on in life and which has stuck. Her active uber gene manifested itself as the ability to control 'cosmic energy' which is actually a form of malleable, telekinetic energy. The energy itself has substance and is almost sticky, and she can use it to fly, propel bolts of the energy at opponents and create thick walls of protection.

Schmetterling wears too much pink. Her costume is composed of varying shades of the colour, and she keeps her blonde hair cut very short. In flight, she manifests energy wings which are, naturally, pink; and can range from a wingspan of 50cm to 2m. She is also usually surrounded by an energy aura which provides her with protection.

Out of costume, Serilda still wears too much pink.
