Hades could oneshot Gildarts on a moment's notice if he desired-- via Grimoire Law.

Hades is far far more powerful then Gildarts. And Gildarts was never in a class of his own, lmao. Are we reading the same manga? Er, no, Bluenote was not outclassed. Bluenote matched him in combat, the former and Gildarts are on the same level. You don't outclass somebody if you can't move after fighting them, that means they wield power on, or near, level with yours. And Makarov above both Gildarts and Blue, as Jakuho said.

As for taking out the kin, it depends on how they attack him. If it's one by one, then I believe he'd managa taking out 5-- since he's far above any single Kin member bar none. Of course if they all attack him at the same time, he's screwed. As for Hades who could just GL them out of commission.(Makarov could do the same. Laxus could do the same, but Gildarts is stronger then Laxus by a good difference overall.)
