We all have to agree, that these fathers are pretty terrible. Jeredy Suno leaves his son to defend himself against Dark Spin and S.T.O.R.M. While that is Chase is trying to survive not dying by these two guys.

Shirong leaves his son to himself with Master Oogway while he traveled and when he returns he tries stealing stuff from the Jade Palace.

Mr. Krabs he is a seriously cheap man and even to his own whale daughter. Simple as that...

Finally Lord Ozai. What else do I have to say, scars his son in an Agni Kai and makes him go through major turmoil throughout 4 seasons of ATLA.

Though we can say that all of these fathers have some good qualities...

Fire Lord Ozai is the worst father and also Mr.Krabs!!!!!!!!!!!!!!

Everyone is a mess but at least the other fathers didn't burn their son's/daughter's eye and force him/her to find a person in order to return home...

^I agree.
