1) In The Galactic Peace Committee, Abe is the reptile-like roommate of the main character, Jake. "Abe -- that wasn't his real name, but it was the name he used on the space station since no human could ever have pronounced his real name -- was similar to a chameleon with his stalk-like eyes and ability to change color, only he was more stockily built and about seven feet long. [...] If something broke, the odds were that Abe could fix it more quickly and cheaply than anyone else. It made him incredibly handy to have around the house, and he was also a very friendly guy. Maybe it was his cold blood, but Abe rarely got upset."
