[botmarley]

Bot Marley is my Autobot Energon Purification Specialist that hung out with Beachcomber before the Great War on Cybertron. He came to Earth and his alt mode became that of a water filtration pipe (a Bong). He and Beachcomber left the Autobots and the war together for a life of peace and relaxation on the beaches of Hawaii. Bot Marley took his name from mistakenly hearing a radio DJ mention the reggae artist Bob Marley as Bot Marley. Before that his name was AEPS (pronounced "Apes"), the acronym for his function back in the old Energon Brewery.

I'll have to dig up some of my old Bot Marley sketches and post them later. It's been my handle on forums since 2005.
