In the Initial Era, Explo first appears in D.O.P.E. Volume 1, Number 14 (1995). He attacks the D.O.P.E. building with a stick of dynamite. Big Mouth comes out to fight him, but when he realizes that Explo has live dynamite, he runs back into the building scared. Meanwhile, Leper's hands put out the lit stick, and his foot kicks Explo in the face. As Pinhead is taking him away, Explo says that they're irritating him and he has a short fuse. After a stunning silence, Pinhead responds, "Boy did that joke bomb!"
