UnrevealedBull

Seeking to steal important information from the Avengers, the mob boss known only as Bull had a plan to strike at what he believed to be their weakest link, Captain America (Steve Rogers), since Captain America was only a "glorified acrobat" in Bull's opinion. After breaking into Avengers Mansion, Bull's men kidnapped the Avenger's butler Jarvis, ensuring Captain America was alone. Taking him by surprise, Captain America was captured, but he escaped his bonds and showed the intruders what a lifetime of training could accomplish. After all his henchmen were defeated, Bull thought he could overpower Captain America, but he was defeated too. The police were called and all were hauled off to prison.
