Cassius Chrome was the last House Robot to be created for the original series of Robot Wars. He appeared exclusively in Series 7, and was modeled on a heavyweight boxer. Cassius Chrome was named in reference to Cassius Clay, the former name of the late heavyweight boxer Muhammad Ali, as well as his chromium silver colour scheme. He relied on his interchangeable 'fists' and pushing power to cause internal damage and shove competitor robots around the arena, although his appearances became limited when the original series of Robot Wars was cancelled after Series 7. Cassius Chrome did not appear in the rebooted series of Robot Wars.
