Everything in this comment is false. Dragonite was easily the most feared BW1 sweeper after the ban of Deoxys-S. There was a point in time when Dragonite was suspected and found to be not broken. There is little doubt that Dragonite and Terrakion were the most powerful sweepers in OU before BW2 came out. And what are you talking about? You didn't even read the rest of that guys post. If you had, you'd know that he actually agrees with Lucario in B+ rank. Anyway, no Lucario doesn't need Crunch or Ice Punch at all. Bullet Punch is great for sweeping offensive teams that pack things like Gengar, ScarfTar, or Terrakion. You should never use Bullet Punch over Extremespeed since it's weaker and hits fewer things. Lucario needs to pick its poison. Either Ground Types, Bulky Ghost/Psychics, or offensive threats. But any of the options is completely viable.
