Allenby is almost the youngest character in the G Gundam series and the only official female gundam fighter in the tournament. She was orphaned at a very young age and was taken in by the government. Her stunning success is but a facade for a brutal training system designed to create the perfect fighter. Her government used a 'berserker' system that boosted her combat acumen by 120% while essentially making her devoid of cognitive thought. She becomes a close friend of Domon, developing a not so small crush on him. Much to the distress of Rain Mikamura. During the semifinals of the Tournament Wong Yunfat used the berserker system to capture and use her for his plan to pilot the Devil Gundam. During the final rounds of the Tournament Domon was about to face Master Asia until Allenby arrived being controled by DG cells and the berserker system trying to challenge him. Rain arrived in the Rising Gundam and rammed her into the ocean. While underwater Allenby's Noble Gundam turned into the Walter Gundam and started attacking Rain. During their skirmish Rain heard Allenbys feelings for Domon and tried to free her from the DG cells effects. After battling for some time Allenby and Rain landed on one of the Docks in Hong Kong continuing their battle. Rain was able to free her with a shot from her Gundams arrow. While trying to find her in the mess Rain encountered her father who came to help cleanse her of the DG cells.
