This article is about the being. For the planet, see Pulse (planet).
Pulse is the Shattered Mirror counterpart of Flare. He arrived through the Shattered Mirror II with SMTBS during the invasion through the Shattered Mirror II. One of the SMU soldiers at the battle commented on Pulse's resemblance to Flare, minus the Parasitic Fluff.
As soon as Pulse noticed his counterpart fighting in the battle below, he soared away from the planet instead. We don't know why he fled, and seeing as the Living Stars have all mysteriously vanished since, maybe we never will.
Physically, Pulse is a silver living star, with what looks like a large orange tear underneath his right eye.
