Well, Wobbuffet is on the Uber list. This is because it can make the foe repeat it's moves, render it unable to escape, then proceed with DOUBLE the damage of the foe. And with Earth-sized HP, and low defensive stats, it can potentially drain all the hit points out of the average Metagross or Mewtwo. If you're still okay with this, I'm fine. Of course, now is the time for YOU to spill the beans. What is your roster?
When i was young and retarded, I used to hack thinking it just punched a special, harmless, code into the game, letting me do whatever I wanted. That didn't turn out well...To this day, I don't hack. To answer your question, I have Kingdra, Latios, Palkia(sinjoh ruins), Mew(got it from an event, didn't hack), Suicune, and Wobbufett. If Wobbuffet isn't allowed, then I have Latias.
