When the Decepticons joined forces with their Beastformer compatriots on Beest once again, the good Beastformers sent an SOS to the Autobots for assistance. Shortly after arriving, Chromedome met up with Kane, a young human boy fighting alongside the good Beastformers.
Kane helped Chromedome and the others untangle themselves from some killer vines. Kane joined with his commander White Leo and aided the Autobots in defeating Alligatoron and the Decepticons.
