Dead Scream is an attack.
Sailor Pluto waves her Garnet Rod back and forth rapidly in front of her. Sailor Pluto first used her unusually strong Dead Scream attack in her debut appearance to stop Sailor Moon, Sailor Venus, Tuxedo Mask, Luna and Artemis from going forward to the Door of Space-Time. It caused intense pain to her victims in a large burst of light purple, glowing energy. She used it a second time to kill Tellu shortly after she reawakened in the present day, saving Sailor Chibi Moon.
