With the recent abductions and replacement with alien lifeforms, Earth's scientists and government came together to collect data and produce an answer to this crisis. After a couple of years and many failed prototypes later, the first Terrestrial Humanoid Units were made. These bipedal beings would forge the pathway to better protection both on and off planet. When proper approval from most countries were given, the creation of the Terrestrial Humanoid Unit, Defensive Model 37, was approved and eventually released to serve as living breathing peacekeepers and protectors of the land. These bio-mechanical lifeforms were purposefully made to have their own free will, and even go through rudimentary and military training, a good majority in the official military and very few taking up civilian positions due primarily to citizen unease about alien DNA being used in their production. When possible, the residual energy signature from the abductions are scanned, intercepted, and a THU-D37 is sent wherever someone else would have been sent to... often ending up on Ramylix V or on Xylimar VII. Using the innate skills they were given, and ability to learn, evolve, and replicate eventually, THU-D37 are bastions that can weather nearly any storm or environment.

In my Discord server for the TR Universe stuff! (Ask for link in notes/DMs!)

The THU-D37 are a species I created for my Tailored Remembrance Worldbuilding Project, but do ask about them, or make characters with em... please do show me if you make a character or art with em, I love it when people acknowledge my work~ C:

Also please do ask about the TTRPG I've been actively developing for it~ ^w^/
