in the beginning of the first season, the botties were unaware of k's reasons for chasing after robots, but eventually learned of the existence of solex and soon began racing dr. k in the search, intercepting the last few robots to possess it before he could extract it. dr. k's plans were delayed when kan-it unintentionally absorbed half the solex he had collected, which ended up in the possession of the botties. needing more, k launched an attack on the botties pit to get the solex in their possession, only for cubix to drive them off while revealing that he possessed crystallized solex. changing tactics, dr. k and the alien devised a plan to deactivate cubix and take some of his solex crystals. adding it to what he possessed, dr. k was able to power a humongous epu he had created, which he then used to transform his hq into the kulminator. in the end, cubix sacrificed himself to defeat kulmintor and destroy the solex within them both. cubix would then be revived by the last remaining traces of solex (obtaining the ability to speak on his own in the process), ending the threat of solex for good.
