He seems to be grumpy and mean. If those are answer choices though, I'd have to say it's 'eager to pick a fight', 'intimidating', and 'commanding of respect'.
Character traits are words that describes someone's personality and qualities. For example, if someone likes to kicks animals for no reason and hurt those weaker than them, they're described as cruel and mean. If someone gives money to the poor and helps others in need, they're described as kind-hearted and warm.
Hope this helps! Good luck!
