Tougeki - Super Battle Opera (SBO), also known as the Arcadia Cup Tournament was an annual Japanese fighting video game tournament hosted by the magazine Arcadia. Several games are represented at a single year's tournament, with the lineup changing every year. Which games are to be represented are decided by the organizers of the event. It was considered one of the two most prestigious fighting game tournaments, along with the Evolution Championship Series. It was suspended indefinitely in 2012.

A fighting game is a genre of video game that involves combat between two or more characters. Fighting game combat often features mechanics such as blocking, grappling, counter-attacking, and chaining attacks together into "combos". Characters generally engage in battle using hand-to-hand combat—often some form of martial arts. The fighting game genre is related to, but distinct from, the beat 'em up genre, which pits large numbers of computer-controlled enemies against one or more player characters.
