Harry makes an entrance at the mob-owned Varsity by blowing the door off its hinges, melting the jukebox, and exploding every lightbulb in the place.
Dresden: "Little pig, little pig, let me in...."
Made even more impressive since Dresden blew the door out towards him so as not to rain splinters on innocent bystanders.
That quote sums up Dresden pretty well. The dude is a big bad wolf.
Harry and Murphy are handcuffed and trapped in an elevator. The scorpion talisman has grown to the size of a French car, poisoned Murphy into unconsciousness, and is trying to rip through the roof of the elevator. Harry knows that shooting fire at it would heat up the car too much to survive. So instead Harry pulls air up from the bottom of the shaft causing them to rise 11 stories and crush the scorpion against the ceiling.
And then the elevator falls all the way back down to the ground floor, where some very surprised paramedics are waiting.
We can't forget the fact that Harry channels the power of a fucking thunderstorm to banish a demon. While naked.
Harry going out to find Victor Sells and stop him from using a thunderstorm to murder him, but while he's in Mac's pub he's stopped by Morgan, who claims that he has proof that Harry has been committing the murders. Harry makes to go sit down and talk...then he grabs one of the heavy wooden chairs and beats Morgan into unconsciousness with it. Keep in mind that Morgan is a Lawful StupidInspector JavertKnight TemplarBFS-carrying wizard parole officer that could have Harry killed at any time.
