Siba (シバ, Shiba?) is a mystery character that appeared on the early VF1 arcade cabinets' character roster under the name "Akira". Game-wise, he appeared in Fighters Megamix but not in the actual VF series. His fighting style is indeterminate, but it is often speculated that he uses Pencak Silat since he wields a sword used in the art in his stance.
Siba is actually from a prototype of Virtua Fighter but was cut from the cast by the time of game's actual release, though an icon featuring him (and mislabelled as "Akira") appears on older Virtua Fighter arcade cabinets. Siba is an Arab in a white and purple outfit equipped with a sword that charges with green energy (the World Fighting Tournament calls for no weapons other than the human body, so this counts as cheating); he is unlocked by defeating the 'Bosses' section. His stage is based upon Wolf's "desert" stage from Virtua Fighter 3.
