While it's not really in continuity, there really wasn't a MH franchise when Gavan aired and generally 1982 had it grouped in many ways with Goggle V. In a way it actually makes sense if that series did take place in the same Sentai uni and just diverged from there: since the threat from Deathdark was exclusively Earth-related, Gavan had all claims to the threats from space for the season and thus both could happen about the same time. (if you want to include all three Space Sherrifs, note that no massive threat from space comes to Earth through Sentai until the Gozma...after Shaider is done. Sure Bio Hunter Silva is within those three years but most of Bioman was "alien stuff that came to Earth and Silva/Barizon is rather small-scale compared to the Gozma)
