Tammy is from Earth-95, a lost member of IRIS who got lost during her latest space expedition, stranding her somewhere amongst the stars. She waits for a rescue and takes bounties along the way to keep herself fed, both by the bounties she's paid and by the bounties she hunts!

Eli from Team Sierra Foxtrot tries to seek her out but ends up on Earth instead, making Tammy still MIA and fending for herself.
