Not really, Haxorus doesn't get weakness to Stealth Rocks, which is cool and awesome. He also has access to a reliable boosting move, which Kyurem-B doesn't get. Kyurem-B doesn't get Earthquake, which sucks because Kyurem-B will get walled by the likes of Tyranitar, Heatran,Magnezone, stuff like that. Now, Haxorus' sprite is badass, and one shouldn't overlook him. I mean seriously, with JUST one Swords Dance boost, lol you better watch out. Its even STRONGER than Kyurem-Bs overall power, and Haxorus will litterally, destroy anything with its Godlike power.
