Budapest is the capital and largest city of Hungary.
Edwin Jarvis' Dishonorable Discharge
Edwin Jarvis, under service of a British Army General, traveled to Budapest and met Ana, the girl who would become his wife, while she worked in a hotel tailor shop. Ana sold him a beautiful tie, and Jarvis quickly fell in love with her.
As World War II began, Ana's safety was endangered given she was Jewish, and Jarvis asked the general to use one of the several letters of transit he carried in his safe to ensure her safety, but he refused to sign. Jarvis had to forge the general's signature, for which he was arrested in London and dishonorably discharged from the Army.
S.H.I.E.L.D. tasked Natasha Romanoff and Clint Barton to participate a mission to Budapest, Hungary. During the mission, they were involved in a situation that would later be remembered by Romanoff during the Battle of New York, as one of the fights she and Barton had against one of the Chitauri groups reminded her of Budapest, something Barton disagreed.
Isabelle Hartley, Lance Hunter, and Idaho worked together in a mission in Budapest, where Idaho cooked something awful. He excused himself saying he did not have the right tools or raw materials to make it work. Besides its awful taste, the meal broke one of Hunter's teeth.
Return to Budapest
After aiding Steve Rogers and Bucky Barnes evade capture during the Clash of the Avengers, Natasha Romanoff became a wanted criminal after T'Challa reported Romanoff's betrayal to Thaddeus Ross. Now a fugitive, Romanoff traveled to Budapest, where she encountered and fought Yelena Belova.
