AlexTheMartian was a Caretaker of AWTeen from 2003-2005. After resigning from being an AWTeen Caretaker in 2005, AlexTheMartian remained on staff as a Teen Patrol member up until 2008 or 2009. He was Object Path Manager and Building Team Leader in AWTeen under Espilae's governorship. He also for a time served as Brock's Caretaker Assistant, a position created in June 2006 in the aftermath of JerMe's resignation.
AlexTheMartian has since started a new development on previously uninhabited Seawing Island of SW City (AW 1683.394S 3871.675E 1.00a 270) and as of June 2011 development has covered most of the island and is still in development.
In 2001, shortly after becoming a citizen of Active Worlds, AlexTheMartian (then blink182skater) started a town named Blinkville, now Moonlight Heights, that same year. The town remained active at least part of each year up until 2009, at the time being the oldest active town in AWTeen.
