No, see.. From what I understand, yes, Lucario becomes more powerful with the more damage he takes, but it in no way does it restore its health. Its attacks just get stronger. So, if he has like 5 health left.. It doesn't matter how ungodly overpowered he is, he's still gonna faint if he gets hit and loses that health. I last read that he was in such bad shape that he had to crawl to my character because he was so weak.. And pokemon faint, they don't exactly die. So if he had fainted, I'm sure Silver or someone would have helped him. I just feel that it's a bit ridiculous that it takes three or more pokemon to take him down after he's that weak. It's also ridiculous that he's fully restored and that he can tap into this "great power" with no repercussions whatsoever.
