Frank Watt was the father of Willie Watt.
Frank Watt was a foreman for a construction company, handling operations of the GoLeM. He was not impressed by his meek and scrawny son and often pushed his son into what he called "hitting" someone "where it hurts".
That, unfortunately, was his undoing as Willie soon turned against him with the help of the GoLeM. In an ironic turn of events, despite nearly being killed by his own son, Frank was proud at the fact that Willie wasn't as meek anymore, but was also guilty and ashamed of what his abusive and rough treatment to his son had led to.
Despite being Willie's father, Frank didn't visit his son in prison, possibly either out of fear or guilt (or both).
