Both series were licensed and localized into English by Canadian entertainment company Nelvana. The English version of the first series aired on the Fox Broadcasting Company's Fox Kids block from September 1, 2001 through November 2, 2002, divided into two American seasons. "Medabots" was Fox Kids highest-rated new series at the time. After the sale of Fox Family Worldwide (the joint venture with Saban Entertainment that previously operated the Fox Kids program block) to The Walt Disney Company, "Medabots" would move to ABC Family. "Damashii", which was adapted as the third American season, aired from September 13, 2003 until May 8, 2004 with later episodes aired as part of the Jetix program block. In Canada, the television series aired on YTV which, along with Nelvana, were owned by Corus Entertainment.
