Gen 6 has Volcanion, Diancie, and Xerneas. Gen 7 has Silvally, Zeraora, and the UBs if you count them. Gen 8 has Zacian, Zamazenta, Eternatus, and Calyrex. Gen 9 has Koraidon, Iron Leaves, Okidogi, Iron Boulder, Fezandipiti, Gouging Fire, Munkidori, Raging Bolt, and Terapagos.
The only generations where the majority of legendaries are at least good are 1, 2, and 3. I say this, again, as a Gen 5 fag.
