I'm very sure they are because they're called the legendary golems (or at least that's their Bulbapedia page) despite probably being the weakest (due to all three of them being very weak to fighting types) and least popular legendaries. And anyways, if they weren't legendaries it would be rather illogical to tie them with Regigigas (who is a legendary).

The regis base stat totals are equal to almost all, if not all, of the lesser legendary trios.
Wait. So does this mean all the Regi haters are just simply underestimating the Regis because of their common weakness to the Fighting-type? (like. I seriously know zero people who give the Regis any sort of respect)
linktake a look yourself, just click on the total tab twice to see the total base stats. and I guess so, never really liked them but don't hate them either
