think of it though, their minions were ranked dragon because the ship destroyed the city, so unbeknownst to the association, the monsters themselves didn't do the damage. Also, these aliens are more experienced at survival and regeneration than attack, as Metzelgald barely landed any attacks after the s-class heroes come. So i think their ranks are respectively overrated
