^ The Hyper Beams I wouldn't say are completely bad. Yes, I am aware of the recharge and that can allow your opponent to do something like set up on you, but there are still some Pokémon that can make okay use of them, like Porygon-Z with Adaptability. Not to mention you can use a Z-Move to turn them into effective 200 power attacks before STAB with no drawbacks at all. When I did a Dark Monotype, I gave the Normalium Z to my Raticate and got Giga Impact near the end, and with Hustle that alongside the Z-Move turned it into an effective 450 power attack, which is so good.
Sure, they're not anything seriously worth using competitively, but they're workable if used right.
