the now abandoned X-Mansion, where they surprise and capture Lady Mastermind when she comes looking for a portal to the X-Men's new domicile on Krakoa. However, when a team of X-Men is sent to investigate the presence of a mutant in the mansion, one of its members - Cypher - manages to establish a rapport with the Sidri, enabling the X-Men to free Lady Mastermind peacefully and permitting the Sidri to guard the portal. Powers and abilities The Sidri are an adaptive biomechanical species with the ability to survive in the vacuum of deep space. Possessing high resistance to extreme cold yet are vulnerable to intense heat, they can project force blasts or other forms of energy from their visor like eye, can grow additional natural body armor, and merge with other Sidri to double their size. They are of a collective consciousness with FTL-flight capacity. References Characters created by Chris Claremont Characters created by Dave Cockrum
