The Creeper 1975 - Ernie Chua (Ernie Chan) artwork

From Detective Comics #448 June 1975

Ernie Chua came onto Detective Comics after Jim Aparo's brief run as artist under Archie Goodwin who had been writing and editing the book. Len Wein took over the scripting with his five-issue "Bat-Murderer" story.

BATMAN: "I thought I told you not to help me, Creeper!"

CREEPER: "Wrong, mortal- - you did tell my alter ego not to aid you - - but no man may give orders to The Creeper!"
