Sin-Sam is the host of Object Fire Reboot. They look like Yin-Yang from Inanimate Insanity II and Taoism from Object Oppose but Sin is very nice and Sam is very evil and mean but don't fight each other and are square. Each three episodes one of them hosts, like in episodes 1a-2b the white side hosted and episode 3 the dark side will host.
Sin-Very Nice and Agreeable
Sam-Very Evil, Mean and Bossy
