After banagher gave full frontal the unicorn gundam, ensign ridhe was tasked with reclaiming it with the banshee

the ensuing battle ended with the destruction of the banshee, only the torso and head remained intact and it was later recovered and repaired with parts from the nu gundam (which in this universe was found a year after the axis incident, amuro and chars escape pod were never found) and recreation of the sazabis funnel rack

In it’s first battle it came in contact with banagher and angelo, in the battle the banshee managed to disable angelos geara Zulu and hold of the sinanju piloted by banagher.

the battle ended when banagher used a psycommu jamming device (similar to the one on the rozen Zulu but more grenade like) to rescue angelo and leave the battlefield

It was then taken to one of the colonies for repairs. Ridhe was almost assassinated by a zeon bomb, leading to the loss of his arm

The science boys over at AE was given the data from the reuse P experiments captured from a baoa qu in the last day of the one year war (yes thunderbolt is kinda canon in this universe) and they improved it a fair bit over the years, especially since psyco frames are no longer being produced.

Ridhe signed off on having his other arm removed to use the reuse P system but the engineers were struggling to crack the banshees system to allow it to even run as an executable (because it would be a right faff to apply this, hell they could hardly even get the cockpit to open)

while they were trying to brute force the banshee into allowing the use of the system the colony came under attack by the sleeves and all out war commenced

In the battle both angelo and banaugher (they were put on the same attack team because banaugher is good at close range combat while angelo is good at sniping, it’s the dream team, ornstein and smough except they hate each other
