Speedball vs. The Comics Code
Please don't finish that sentence.
The alliterative and - erm, other - talents of Leaper Logan are to be found in Speedball: The Masked Marvel #3, pencils and plot by Steve Ditko, script by Roger Stern, Leaper Logan's outfit by Mel Brooks, apparently.
EDIT: Neilalien.com was kind enough to alert people to my earlier post, sending a ton of readers my way. Why don't you return the favor?
