Grokonos was the first reptile character I've ever created, back in 2000, as a written character back then but later actually drawn in 2003 for one of my elven character's story, Lylah. Here he's wearing a bathing suit and posing in a slightly attracting way, but in reality he wouldn't be up for it, in fact: He was written as a villain character, leading a karawan of slave traders. =P Here are some doodles of him:

Also first designs of Blaze and Lylah, originally supposed to be Discworld fancharacters, but they got their own stories, which weren't finished at the time: http://sta.sh/01timravb1mx
