They became best friends, and met in secret at the Metropolis East Leisure Centre. When Sonic the Hedgehog came looking for Badnik, Badnik was terrified. Smokey defended him, saying that if Sonic wanted to destroy his friend, then he would have to go through Smokey first. Sonic agreed to let Badnik go, although Smokey did later claim that Sonic had smashed him in order to trick a couple of Troopers that were also looking for the "rogue" Badnik.
Badnik once allowed Smokey to climb inside his casing, in order to protect the young bear from a Trooper's gunfire. Sonic assumed that Badnik was attempting to convert Smokey into its organic battery.
Badnik is very quiet. Smokey expressed great surprise when he revealed he could talk.
