Pugna

Finally, there was the fiercest...

Of the seven titanframes, Pugna is by far the most independent. Over the course of many years, each new pilot left an imprint of their essence in the geometrid core of the frame, and this process came to shape its own personality, and indeed future pilots in turn. So it was that Pugna - and each successive pilot - developed a curious tendency. They valued freedom, often siding with the underdog, leading to a pattern of rogue actions and betrayal. Nothing in Paradise could shift its stubborn conviction. Indeed, Pugna only favors those with the strength of will to fight for those who cannot fight at all. - The Annals of Catalyst II (Revised)

Summary

Pugna was the first titanframe to be completed, and best embodies the purpose of these titanic creations - a design meant to wage war. As its name implies, Pugna's specialty is combat by any means necessary, typically brawling, and was built to be resilient, flexible, uncompromising, and without mercy. This monster does not know the meaning of holding back, and under no circumstances will it surrender to any foe. It joins Armis and Feminam in a trio of Titanframes, designed to work as a cohesive team to dominate anyone and anything.
As such, only the most steadfast and determined individuals have the strength of will to bond with the geometrid Pugna, and thus be able to control the titanframe. However, there is a caveat to this strength, for it is also a weakness. No matter what faction it belongs to, there is no reclaiming it should its pilot decide to pursue their own path. Only brute force can bring it down, and the pilot must be killed to stop it. This often requires using the other titanframes to fight it; the only weapons in the world that could even contend with it. That is the nature of Pugna. Designed to fight to the last breath, and never to yield.
