It has been a very long time since he was created. I don't remember having anything in mind but wanting a scrapper on Infinity. (My first scrapper was on Virtue.) Once the Texan Eagle name came to me, his origin sort of flowed naturally. I didn't need to write it later.
I lived in West Texas while going to college. There is an annual "Rattlesnake Roundup" in Sweetwater. I'm sure it inspired part of Tex' biography.
For years he was one of my main guys on Infinity. I had been playing him less and less though, favoring newer characters. Finally I transferred him to Freedom just to open a slot for a new character.
