User blog comment:The Maverick013/Do you consider Dragon Ball: Episode of Bardock as canon?/@comment-4640094-20111009212741

Last time I checked Bardock died when Frieza destroyed Planet Vegeta and never became a Super Saiyan. Besides he somehow was in the past. So no, no way can it be cannon. Especially if Frieza and his family are the descendants of Chilled then that makes no sense why they be alive at the same time.
