10 Worst Things Batman Did To Villains
10. Bootface - Batman And Robin #10
Sure, Batman doesn't kill, but that doesn't stop him from inflicting permanent wounds, now does it?
In Tomasi and Gleason's run on Batman and Robin this idea was explored through a group of criminals that had all been permanently damaged by Batman or Robin.
There was Smush, three men merged into one monstrosity at the hands of Robin; Scallop, who had one of Batman's arm spikes go through her ear; Bat Head, a guy with a batarang lodged in his skull, and Bootface - who was kicked in the face by Batman and had the imprint melted into his skin.
The melting part came as a result of Bootface using a flamethrower at the time of the incident, leaving the villain with some of the worst facial scarring in comic history and hence arguably making him the worst of the aforementioned group.
