Angriest

His face was the angriest out of everyone's.

He was the angriest man I've ever had the misfortune to meet!

Tom was angry, Mary was even angrier, and John was the angriest.

This is probably the angriest he's ever been. Admirable restraint on his part not to lash out.

Tom was angry, and Mary was much angrier, but John was angriest of all.

He was a squat, corpulent, middle-sized man, with something of the gentleman about him, and that peculiar mild tone—especially while he was inflicting punishment—which is so much more terrible to children than the angriest looks and gestures.

I'm the angriest I've ever been.
