Ronald "Ron" Stoppable is Kim Possible's lifelong best friend and finally boyfriend, mainly serving as her faithful sidekick during missions. He is portrayed almost oppositely to Kim, typically getting low grades and tending to slacking off, and overall being shown to be less capable than her. Although note, on some very rare occasions he does seem almost as capable as Kim and he got less lazy as time went on. He is also shown to be an eccentric student with an erratic and contradictory personality. Some of his schoolmates view him as weird and odd and often refer to him as a "loser".
