One of the many Batman villains created by tangents on the Flop House.
Origin[]
The Contest Ruiner was driven mad by toxic chemicals in the glue of the return envelope in the 80th Publisher's Clearing House sweepstakes entry that was marked "guaranteed winner". Incredibly knowledgeable due to his extremely affordable subscriptions to many informative magazines, he tricks people into getting into contests, then he ruins them by revealing tricks, answering faster, or just throwing away the entries. Currently being sued by the Riddler for copyright infringement. (Riddler got the idea from the lawsuit against him by Guess? Jeans.)
