In these moments, he scares those around him and leaves them shaken.

Frank has also shown that he would give up his own children if it meant he could get booze (or money to get booze).ĭespite being easygoing, he has been shown to get very frustrated or fall into a rage at certain times. He was also abusive, conniving, being in Lip's and his own words, a "total f*cking asshole." He provides next to nothing in the way of parenting or financial support and usually serves as one of the main headaches in the Gallagher household. He hadn’t done anything in his life but collect disability checks and get intoxicated. Frank was careless, selfish, and narcissistic.

A hopeless alcoholic and addict, Frank was usually shown passed out drunk on the floors around the house when he was not at the bar spending what little money the family has.
