Tiger Mask W

-Both animes feature a boy (or actually two boys in case of Tiger Mask) compete in a sport, in which his father was also good at. In case of Gundam, Sei's father was the champion of gunpla battle, but in Tiger Mask the father of the two tigers was injured by the man called yellow devil and now they are trying to get revenge on him. -They are both shounen animes, that don't offer basicly anything besides battles of mechs or wrestling matches respectively. -In both cases the protagonists are facing multiple troubles on their way, due to the fact that they are facing an evil organisation, that is trying to get rid of them. -Both are a part of an franchise created a long time ago. read more 

Both anime about wrestlers and wrestling. Both anime about the guys who want to become the strongest wrestlers. The young guys of both anime challenge the best wrestler of promotion. In the course of a career they meet strong rivals and tested for dangerous techniques currently. The guys of both anime expect startling twists in their careers. 

Both of these anime are extremely campy, but not in a bad way. They take the sport in their anime so seriously that one can die from it. If you liked one, you'll like the other. Also, watch Beyblade in sub because the dub track is really lackluster. 

These wrestling anime were animated by Toei Animation, are sequels following the next generation of wrestlers and in my opinion share the same masculine spirit for the sport.
