The Ouroboros was an old mech.
Hardly any of its original parts and materials remained intact and attached to the constantly evolving mech frame of this famous Terran ace mech.
As Axelar Streon steadily grew up and matured into an increasingly more formidable mech pilot, his chosen machine could not be allowed to remain stagnant.
This was why the Streon Ancient Clan assigned numerous highly reputable and competent mech designers to repair, modify and most importantly upgrade the Ouroboros over the years.
It had been difficult for Axelar to insist on piloting the same mech on a continuous basis over the span of an entire century!
Since the first time he piloted it in a mech arena and won a glorious victory against a much more conventional first-class multipurpose mech, Axelar had fallen in love with the Ouroboros.
