Biography: Irma was once a basic bilby who would be captured by Dr. Neo Cortex's Lab Assistants in the past. That happened after Ripper Roo's mutation and prior to Crash and Coco's capture and mutation.
The female bilby was amongst the captured animals to be rescued by a 16 year old Irma Williams, the only daughter of Professor Garret Williams *Who used to work for Cortex as his researcher, but would then turn against him when he learns Dr. Cortex is evil* and her friends, who were animal rights activists as an attempt to save them from Dr. Cortex and mutate them with the Evolvo-Ray to become his Henchmen. Dr. Cortex attempted to make sure one of the animals gets mutated, and the beam from the Evolvo-Ray in a form of a hand-held ray gun nearly hits the bilby.
When Irma and her friends try to escape Castle Cortex with the animals, they were surrounded by the Lab Assistants who ended up capturing them, as Irma and the bilby were the only ones who fled because one of them begged her to run for her life.
The girl ran as fast as she can but ended up by the cliff, but when the Lab Assistants were about to catch her to capture the bilby, she jumped from the cliff and ended up falling to her death, sacrificing her life to save the bilby and ensure neither Cortex nor his minions kidnapped the bilby.
About 10 minutes later, Professor Williams was searching for his daughter, only to find his only relative dead, holding a shivering bilby. He took her back to his lab somewhere in the Wumpa Islands. One our later, which is midnight, a bilby suddenly mutated into an anthropomorphic bilby *which proved the Evolvo-Ray did in fact hit her an hour*, which surprised the professor, as he named her after his late daughter, "Irma Bilby", who would then be his assistant for six years.
After six years passed *Before two years later being Skylanders: Imaginators*, Irma would meet Crash Bandicoot and Aku Aku for the first time after saving her from the the sword wielding henchmen *who called her a "Rabbit-Eared Bandicoot"* of Igneous Iguana *A mutated iguana and dark arts warlock and villain OC* who tried to steal an ancient relic from her that she's taking home for Professor Williams to study, and she also befriended Coco Bandicoot and Crunch Bandicoot before heading off on an adventure to stop Igneous from stealing ancient artifacts and crystals altogether that could destroy all life on the planet where he would remake the world into a new empire to conquer.
