Miro Yakkav was a mercenary pilot belonging to the independent hireable squadron known as The Flyboys. Originally a test pilot and designer for the Srav Federation, he fled it after being marked a political dissent following him making a derogatory comment regarding Srav leader Jasef Yuiln. He took with him a prototype design that would eventually become the Zulkrum-class heavy interceptor, which he developed into his personal fightercraft, the Z-PR01 Troyusha. Miro was known for what was considered to be a somewhat maniacal disposition, but was nonetheless regarded as an expert and invaluable pilot by his fellows.
