The BEAST trio are not uber cause they don't have to great stats and attacks. I think...GrassForStarter said:Tyranitar can easily be destroyed by nearly any fighting type due to it's 4x weakness to fighting...I've never had a problem with it. A Zangoose and Charizard, or nearly any pokémon with a decent attack stat that learns Brick Break can take it out in one blow, and many of them ahve highter speed than Tyranitar too.
Salamence can be a pain in battle, but can also be quite easily beaten if you know what you're doing. Use an Ice or Dragon type. What actually is troublesome with Salamence is it's movepool. It can learn many attacks, but it isn't as hard to beat as a Mewtwo.
Wobbuffet is a Uber. Whatever pokémon you may have that enters the arena and that doesn't have a super effective move and higher speed than Wobbuffet will be slaughtered. Counter/Mirror Coat/Encore/Destiny Bond are all made for K.O.ing.
May I ask why the Legendary Dogs aren't counted as Ubers?
