However, within the Clan Smoke Jaguartouman, the Stormcrow was especially common during the Clan Invasion and was codenamed the Ryoken by the warriors of the DCMS who encountered it. Because of its versatility through its combination of mobility, armor, and firepower in its various configurations, the Stormcrow is a feared opponent on the battlefield.
The Stormcrow was designed by Clan Hell's Horses and debuted during the Battle of Tokasha. It is also implied that Stormcrowprototypes were produced on Tokasha at Tokasha MechWorks. However, prototypes of the Stormcrow had only just debuted when Clan Ghost Bear won Tokasha through the Battle of Tokasha. As a result of the upheaval, design copies and moulds for the Stormcrowwere scattered throughout Clan space. The final production version of the Stormcrow debuted in 2930, when Clan Snow Raven scientists finished with a series of minor design changes and rechristened the OmniMech. [Source: Sarna]
