chapter 1 The Great Gatsby 10

Tom is described as strong, powerful, arrogant, and domineering. He was around thirty years old, with blonde hair, and a husky voice.

From the text:

Now he was a sturdy straw-haired man of thirty with a rather hard mouth and a supercilious manner. Two shining arrogant eyes had established dominance over his face and gave him the appearance of always leaning aggressively forward. Not even the effeminate swank of his riding clothes could hide the enormous power of that body — he seemed to fill those glistening boots until he strained the top lacing, and you could see a great pack of muscle shifting when his shoulder moved under his thin coat. It was a body capable of enormous leverage — a cruel body.

His speaking voice, a gruff husky tenor, added to the impression of fractiousness he conveyed.
