Howard is the janitor of S.T.A.R. Labs.
Work at S.T.A.R. Labs and Kidnapping
During his time working at S.T.A.R. Labs, Howard was mopping the floors when Silas Stone, the head of the job, leaves and informed him the Red Room is all his. Howard conversed with Silas about his Victor's accident. To hear those sympathetic words, Silas thanked Howard before leaving to go home.
Meanwhile, Howard was mopping the floor while whistling to himself. All of a sudden, he heard a crashing sound inside the Red Room. He then went in there to take a look inside the lab and saw a shadow of a creature growling behind the curtains. Howard opened the curtains and suddenly becomes terrified of what he saw; a parademon, who was alerted and kidnapped the janitor and the staff of S.T.A.R. Labs, and took them all to Gotham Harbor.

He was then thrown onto the ground floor when Steppenwolf grabbed Silas Stone instead to demand the Mother Box's whereabouts.
