The Mysterons possess the ability to reconstruct exact replicas of objects or persons. It is due to this remarkable ability that they are able to re-create their city following Black's attack. They also employ this power from time to time during the "Mysteronisation" process, which imbues the reconstruction (dubbed "replicant" by Spectrum) with the power of "retro-metabolisation" – the replicant is able to heal completely from almost any injury, including fatal ones. The only known survivor of the process is Scarlet, who retains his retro-metabolism and remains virtually indestructible, an ability which is a great asset in his work.
