Born in San Antonio, Texas to a military family, Dex was never home a lot. His Father Leo Harper, was a PJ (Para-rescue) in the United States Air Force. Moving all across the US and even Europe as he grew up. Leo was always gone, so Dex had that missing feeling inside, he needed that father figure in his life. As time grew on Dex also got very interested in the thought of becoming a PJ himself. After much thought and discussion with his father. He was shipped out back to San Antonio for Air Force basic training.
After a short 8 weeks, Dex started his selection process to become a PJ, he knew it would be hard, but not this. After all PJ's are responsible for the daunting task of rescuing the most elite soldiers in the US military. After months and months of Training. He finally earned his Maroon Beret. He was so proud of himself, so was his father. Not soon after, his father passed away of a tragic car accident. Leaving Dex with that same empty feeling he felt as a kid. Pushing through to more recent times.
Soon after his fathers passing he was put on stand by in 2009 for the bloody civil war, just in case anything happens. Well little did he know, he was in way too deep. On a routine training mission him and his fellow PJ's and pilots crashed. Leaving them stranded. Dex was the only survivor. Lucky for him, the only thing hurting was his head, with a 2 inch gash across his forehead. By this time things have already fell into chaos. Later he met some of the members of the "Brotherhood" by accident. After being somewhat skeptical of what they were up to and their view on everything. He finally decided that the military was not coming for him, he was just a disposable PJ, if they even if the PJ's are still a thing. After getting to know everyone he was adopted, he was now a brother.
As for now, the rest of the story is unwritten. Only time will tell what is next.
