Code Name: Leprechaun
Real Name: Siobhan O'Mally
Species: 23rd Century adventurer / human.
Powers: via 23rd century tech, flight, energy projection, teleportation, time travel.
History: Siobhan was a bored school kid looking for some excitement when she accidentally stumbled on a cache of obsolete technology (believed to belong to the then deceased Benefactor). A capable and inquisitive child she began fixing up the equipment and combined it into a costume she used to become the Leprechaun. Learning of the plans of Time Travelling villain Time Keeper, she used her new abilities to chase him to the present day. There her futuristic technology gave her the appearance of being capable of magic, some people actually believing she was a real leprechaun due to her powers and small stature.
Weakness: she relies on her future tech, which is difficult to repair using contemporary equipment, plus her youthful, and impetuous approach to crime fighting often leaves her vulnerable.
