Chore is kind of a pain to be around. Nobody agrees with anything he ever says, and he's always talking, so most learn to either tune him out or pointedly avoid his presence. One almost-interesting thing will invariably happen to him in a given decacycle, but he will mention this thing at least three times in quick succession the next time he sees you, give you a bonus summary shortly later, and then forget he told you in the first place, at which point the whole process repeats itself. Furthermore, he will throw a tantrum if he feels the slightest unappreciated. His observations are funny, blast you.
Chore does reasonably good work as a construction crane, and is something of a workaholic. Despite his small size, he can lift up to two hundred astrokligs. When Powerlinxed to a larger Transformer, he can create a thin forceshield around his partner that can shield both from light projectiles.
After he was created by the Last Autobot to help rebuild Cybertron, the Autobot bulk, Walkertron, somehow befriended Chore and learned to tolerate the little bugger. Chore died in the Mini-Con Civil War due to as-of-yet-undisclosed circumstances.
