holy fuck. just noticed beedrill is 150 attack adaptability, lucario was 145 adaptability.......gGgggG
Lucario had a 120 BP move to use Adapatability with, and could go special/mixed if it wanted.
252+ Atk Adaptability Mega Lucario Close Combat vs. 252 HP / 4 Def Jirachi: 310-366 (76.7 - 90.5%)
252+ Atk Adaptability Beedrill X-Scissor vs. 252 HP / 4 Def Jirachi: 214-252 (52.9 - 62.3%)
Base power of moves really matter, it's why Altaria could end up being a decent dragon dance sweeper despite the low base attack (110 base Pixilate Return hits harder than X-zard 130 base Tough Claws Dragon Claw.)
The coverage is also very poor, Fighting STAB is pretty good to begin with but Lucario had plenty of coverage to go with it. Bug/Poison is awful, notably resisted by steel (and Ghost and Poison I guess,) and there's also numerous dual types that will make excellent checks to it, namely Gliscor, LandoT, Aerodactyl, and Terrakion.
There's also 65/40/80 bulk compared to Luke's 70/88/70. Beedrill is frail as hell, and weak to sneaky stones to boot.
So yeah, Beedrill got a
massive improvement and will probably be viable enough in OU, which is pretty amazing for something that has been a total shitmon for the last ~15 years, but I personally don't expect all that much out if it.
