The Mindbreaker Beast
"Inhabitants of the world still speak of how the little canine sent the dragon-creature howling through space..."
The Mindbreaker Beast is a winged dragon monster who feeds on the mental energy of living beings. Krypto, the Superdog battles the monster on an alien world and defeats it, but not without suffering psychogenic amnesia as a result of the Mindbreaker Beast using its mental powers on him (S No. 287, May 1975: "Who Was That Dog I Saw You With Last Night?").
