Signature Moves

I like to think of one of my Pokemon's moves as it's signature move.  This move is usually the same type as it's Pokemon, and powerful.  For example, my Cobalion's (And you said I couldn't catch Cobalion) signature move is Flash Cannon.  My Simisage's is Energy Ball, my Emboar's is Fire Pledge, and my Rotom's is Volt Switch.  So this time, I'm asking YOU something.  Let me know in the comments some of your Pokemon's signature moves.  (BTW, I made this up.  This doesn't help with anything in the games.)
