Bliss was the daughter of a father who worked in the Rodentian quarry. As a young girl her father was brutally murdered before her eyes at the hands of Rigellian soldiers and she attempted to insight a riot amongst the other men in retaliation. However, the the other Rodentians fled in terror of the brutal Rigellians and left Bliss to fend for herself. She was saved at the last minute by Tom Walker, and has traveled with him ever since. Now an adult, she serves as the field commander for Walker's Rodentian Freedom Fighters, the Rodentech Astronautics Taskforce.
Major Tom Walker II and his co-pilot, Matthews, was shot down over Rodentia-3 in the ending days of the Third Great Intergalactic War while carrying a cargo of experimental cybernetic technology. Matthews was killed instantly in the crash, while Walker survived with extensive damage to the left side of his body (he lost an arm, leg and an eye). Using the experimental technology to replace his limbs and build advanced weaponry, Walker has assembled a team of Rodentian orphans and now leads them in an attempt to overthrow their Rigellian oppressors.
