The combo began as a discovered possibility
The familiar story starts with Street Fighter II, released in 1991. While testing the game, players found that an attack could sometimes lead into another before the opponent had time to recover. The sequence was not just two lucky hits: the first blow left the opponent briefly unable to act, creating a narrow opening for the next one.
That helpless interval is called hit stun. A combo works when the attacker can use it—and, in some cases, cancel the recovery animation of one move—to start another attack before the defender regains control. The defender sees the hits arrive as one connected sequence rather than getting a chance to block between them.
A glitch became a design tool
The important shift was not simply that players found a trick. The sequences were exciting, rewarded precise timing, and gave skilled players another way to use familiar moves. Rather than remove the possibility, the designers allowed it to remain. Players then explored which attacks could connect, turning an unexpected interaction into something they could practice and plan around.
Later fighting games made combos more deliberate, with systems and timing built to support them. But the basic appeal remains the same: a player recognizes a brief opening, acts before it closes, and keeps the opponent caught in the consequences of the first hit. That discovery helped make combos a defining part of the genre—not because every game copied one exact sequence, but because the mechanic turned a moment of advantage into a test of timing, knowledge, and execution.
