He gives his Pokemon "bro badges" whenever they pull off one of these in a cinch of what would be extremely close to a death, or along those lines. Here are all the bro badges he has given, in order:
Omelette (Illumise): After Devin desperately looks for something to do against Wattson's Magneton after it kills Waffles (Combusken), he spends around 20 minutes stalling it out of PP for all its attacking moves, and manages to knock it out, even while paralyzed and with no healing items left. It also puts the final blow on that Manectric.
Sushi (Tentacool): Gives his life against Wattson's Manectric, but not without poisoning it with Poison Sting, confusing it with Supersonic and lowering its Defense with Acid, all three of which were critical to knocking out the Manectric.
Pizza (Dustox): Similarly helped to stall out the Magneton much like Omelette did. Also used Protect to stall out Norman's Slaking. Similarly, he also used Protect at just the time when Wattson's Voltorb used Selfdestruct.
Frittata (Crobat): After Norman's Belly Drummed Linoone knocks Couscous (Graveler) out with a critical hit on Facade, Frittata survives it with 4 HP left, allowing him to knock it out.
Fries (Linoone): Against Winona, survives a critical hit Earthquake after a Dragon Dance with 3 HP, allowing him to 2HKO her with Ice Beam. In the past three gym battles prior to this, he had had four deaths, three of which were due to critical hits.
Spaghetti (Gyarados): In a double battle at the end of Victory Road, survives a Slaking's unexpected Thunderbolt with 21 HP.
Taquito (Magneton): While not specifically mentioned what earned it the bro badge, it did survive an Endeavor in the Fortree Gym and hold its own for a bit against Drake.
