World's Finest Comics #251 [1978]

Part of a short run of Creeper stories Ditko wrote and drew and in the late 1970s, which saw Jack Ryder as the head of a security team at Cosmic Broadcasting, this time tasked with foiling an extortion scheme led by a masked figure who gives the 8-page story its name, "The Disrupter".

Ditko did a lot of interesting slapstick humour in this series, which works well with the acrobatic abilities and quick change transformations of the character.  

All of Ditko's Creeper stories were collected in THE CREEPER BY STEVE DITKO [2010].
