A mixed Bidoof with pretty good coverage. Bidoof has a pretty poor physical movepool, so I just figured why not abuse Simple with Work Up?
Bidoof @ Eviolite Trait: Simple Level: 5 EVs: 236 Atk / 236 SAtk / 36 Def Rash Nature - Work Up - Return - Superpower - Shadow Ball
EVs and Nature give him 14 in each attack stat, perfect to be boosted. Work Up turns Bidoof into a killer by boosting both attacking stats by 2 stages. Return is a nice powerful STAB move. Superpower seems very fitting for Bidoof, and covers the Rock and Steel types Return can't hit. The attack drop is not minded because of the boosts. Shadow Ball covers Ghost types who are immune to it's two other attacking moves.
Bidoof is god. Bidoof @ Eviolite Adamant Nature Trait: Simple EVs: 204 HP / 236 Atk / 36 Def -Curse -Aqua Tail -Return -Quick Attack Return & Aqua tail for good damage and coverage, quick attack for priority! Curse sets up:P and with simple it is a +2 Atk and +2 Def
Or if you want to run bidoof in ubers... moody!
This cute little beaver is no other than the Pokémon version of Rick Astley. It also has not one, not two, but THREE God-tier abilities in Simple, Unaware and Moody. I guess that is why it is said to create Arceus huh?
Gen VII LC Bidoof using 0.01% of its power Bidoof @ Eviolite Level: 5 Ability: Simple EVs: 236 Atk / 116 Def / 116 SpD / 28 Spe Adamant Nature - Swords Dance - Return/Double Edge - Quick Attack/Aqua Tail - Crunch/Aqua Tail Simple boosted Swords Dance awakens Bidoof's power to a fair-game amount (Moody is so broken that it only uses it against foes like Mega Rayquaza) Return is STAB and shows how lovely and TERRIFYING it can be Double Edge is another STAB and shows no mercy to its mere mortal foes Quick Attack showcases a speed 100x higher than Deoxys-Speed and even Regieleki Crunch punishes evil Ghost types for being immune to its strongest attacks Aqua Tail punishes evil ROCK types for trying to withstand its strongest attacks
