Diggs

Diggs was an Angosian turned Changeling, and a rogue, in the late 24th and early 25th century. 

History
Diggs was born Angosian sometime in the 24th century. In 2387, Diggs and two accomplices attempted to steal latinum from the Central Bank of Lissepia, but the robbery failed by the group's own ineptitude. Sometime before or during 2391, the Traveling Link, in radical attempt at procreation, transformed Diggs into a Changeling. The change caused Diggs' unruly tendencies to be imprinted on the Traveling Link, leading them to harass the colony world of Gault. This change would be temporary, on both sides, and Diggs unexpectedly turned back into an Angosian. ("The Needs of the Plenty")

By 2410, Diggs had somehow turned back into a Changeling, and spent his time trying to learn about himself. As part of this process, after witnessing Yuffie Samya's sister, Tatsu, being abducted by Solanae, he took Tatsu's place until being discovered by Samya. He was then left to Samya's 10 year old niece, Yori, who was so confident that she maintained control over him. ("")

Soon after, Diggs and Yori became a team and were off having "space adventures", last being reported as infiltrating the Orion slave trade. ("")
