The Mystery Men

Found these pics on google. I'm about to scour every single batman comic I have (about 400 issues) and look... I invite you to do the same thing.
These two cops seem to be in everything. Both marvel AND DC. Time for a scavenger hunt. WHO'S WITH ME?!?!?!?!Here's the kicker. As you can tell, these comics are from batman and spiderman. both from two different companies (DC and Marvel). both from two different writers. Different artists. Different cities... Different EVERYTHING... so who the hell are these two dudes?!?!?!?!
