I Guess I'm Not Powerful Enough To Defeat Him! (Mega Man X)

Mega Man X: I guess I'm not powerful enough to defeat him...
Zero: X, you shouldn't expect to defeat him, he is designed to be a war 
machine. Remember, you have not reached full power yet.
If you use all the abilities you were designed with, you should become 
stronger... You may even become as powerful as I am.
I'll scout ahead and collect as much information on Sigma's fortress as I 
can. I'll meet up with you when you get there. See you later!
X, I know you can do it!
