Batman's Profile on "Loose Lips"
''Leblanc was a small time gun runner who fell in with Penguin's crew and now works exclusively for Cobblepot. Leblanc conducts arms deals with various buyers and sellers all over the city. He fancies himself a comedian and ladies man but he's nothing more than a common criminal who should be behind bars.''

Batman: Arkham Origins
During a particular snowy winter, Leblanc was dispatched to commence an arms deal with a gang of criminals (presumably Bane's gang) by Cobblepot. Because of his ties to Cobblepot, the vigilante Batman sought him out to track his boss down to question him about information relating to Black Mask and the eight assassins he hired. At 9:00 PM of Christmas Eve near the city hall, Leblanc met up with the criminals and, after asking what they wanted for Christmas, deduced they wanted the requested arms. He then proceeded to check their payment to see if they were "naughty or nice." Batman deduced from their interaction from above that he was the figurehead for the arms deal. Leblanc then entered into a dispute with the criminals, as the latter were certain there was more to his stock than just the sniper rifle in the deal. Batman then ambushed them and, after taking out both the criminals and Leblanc's accompanying Penguin thugs, interrogated Leblanc by stranglehold about Cobblepot's location. However, Batman accidentally knocked him unconscious due to applying too much pressure to his neck. He then woke up only to find himself being dangled by the masked vigilante above a Christmas tree at City Hall's premises. Leblanc demanded to be let go, with Batman complying by dropping him, having tied a cable to his leg earlier to stop him from falling. He then offered Batman any information he needed as long as he is spared. However, Batman, having confiscated Leblanc's cell phone and received a text from Cobblepot inquiring the state of the deal, revealed he didn't need Leblanc anymore and dropped him, although not before ensuring he didn't end up killed by the fall by having him fall on the tree. Leblanc then cursed him out as being crazy.

Some time later, Leblanc was arrested by the GCPD, with his disruptor being confiscated. He was later interrogated by one of the GCPD officers, Marks, regarding the disruptor. Leblanc refused to give details on it. Marks then proceeded to have the officers in charge of evidence lockup take a look at it with the implied threat of destroying it if Leblanc doesn't talk. Leblanc then indicated that he'll have his cousin at the Gazette do a report on them, such as their extortions of Penguin's gang. However, Batman ended up knocking out Marks, causing Leblanc to panic. Batman then interrogated him about the disruptor's abilities, with Leblanc eventually confessing to its secrets when Batman implied that he'll take him to the roof for interrogation again if he doesn't talk immediately, with Batman knocking him out afterwards.
