He is reputed to be one of the Hero Factory's strongest active Heroes. He is able to withstand blows that would destroy armored vehicles. Bulk's artificial intelligence is less developed than others, which he sometimes feels self-conscious about, but he makes up for this intelligence deficiency with sheer power.
He had also attempted to cultivate leadership qualities, offering his tutelage to rookie Nathan Evo. His attitude brought him into conflict with the similarly headstrong new rookie on the team Rocka, who was modeled after Furno himself, though Furno grew to accept the rookie. Time and missions have tempered his overconfidence, though he is still very eager. This amount of self-confidence forced him to push his own limits in order to succeed at harder tasks, even during his downtime. He was also very overconfident, and believed he had the skill to succeed at any task. As a rookie, Furno was impatient but passionate, and eager to prove himself, especially to team leader Stormer.
The series revolves around the Hero Factory, a crime-fighting organization that manufacture robotic heroes to fight and apprehend criminals across the galaxy and protect a similarly robotic populace.
Hero Factory is an animated TV series based on the Lego toy series of the same name and produced by Threshold Animation Studios for The Lego Group and Geely.
