Daughter of esteemed alien hunter, Barbara Stellars, Ellen follows in her mother’s footsteps, but fails to truly build on the family name. She lacks training and consequently focuses her efforts on destroying the snails, as their lazy and unimposing nature makes them easy targets. She sees all aliens as evil, rendering her as more of a threat than an ally. She has been known to reluctantly team up with the snails when facing a more dangerous alien foe on occasion, but these truces never last long though. Ellen is stubborn and prideful, but she is more grounded in reality than most characters.
