(1987). After his introduction, he later occasionally appears in Green Lantern Corps group scenes. In the Tales of the Green Lantern Corps Annual #3 story "In the Blackest Night", Katma Tui is sent by the Guardians of the Universe to a lightless region of space known as the Obsidian Deeps, in order to recruit a new Green Lantern to protect that region of space. Despite the absolute darkness of the Deeps, Katma's power ring led her unerringly to a completely fearless and honest resident of the Deeps: Rot Lop Fan. However, as Rot Lop Fan's species had evolved in darkness, they had no concept of light and color, and thus Katma Tui was unable to explain how the power ring worked (it projects solid rays of light manifested by the bearer's will power). Realizing that his species operates by hearing, Katma coaches him to create a hand bell with the ring, and describes the Green Lantern Corps as the "F-Sharp Bell Corps" — "F-Sharp" being a reassuring note for Rot Lop Fan's race in the same manner that green is a reassuring color, and the ring's powers in terms of sound instead of light. She also composes a new oath for him to recite: In loudest din or hush profound my ears hear evil's slightest sound let those who toll out evil's knell beware my power, the F-Sharp Bell! Having solved this dilemma, Katma leaves Rot Lop Fan to protect his people, not mentioning the ring's weakness to yellow as the colourless space made it relatively pointless; although, she privately notes that in some ways, Rot Lop Fan cannot be counted as a member of the "Green Lantern" Corps as he has truthfully never heard of them. Rot Lop Fan later appears in several group scenes, including in the Crisis on Infinite Earths storyline when the Guardians of the Universe depart this plane of existence with the Zamarons, at the trial of Sinestro, on page 3 of the bar scene in Green Lantern #56 (volume 3/Nov 94) and in a group of ex-Green Lanterns freed from slavers by Warrior. Rot Lop Fan has apparently been reinstated as a Green Lantern after the rebirth of the Corps. He appears in the backgrounds in a few scenes in the Green Lantern live-action film and is part of the 8-inch toyline. Saarek Saarek claims to be able to speak with the dead. He
