Beside Pain is a Ribbons-based clone who has the same type base sequence pattern as Ribbons, pattern type-0026, and Veda identifies Beside with registration number 08368-SA846. He is an Innovade who first appeared in Mobile Suit Gundam 00P as the MS pilot of CBY-001 1 Gundam.
Like Ribbons, Beside can transfer himself into another body if his current one is in danger. He also has the "Install" ability which forces a limited amount of his personal data into another Innovade in order to control their body.
