― Lt. Gronk leads his troops into battle, under Carmelita's command[src]
Lieutenant Gronk was the leader of a team of gorilla mercenaries who were initially hired by Inspector Carmelita Fox to help her capture the Cooper Gang. However, she also used them in Venice to help her stop the local crime boss Octavio. All the members of his team were equipped with missile launchers and jetpacks.
Later on, Carmelita took Gronk and his team with her while the world's most expensive Bavarian chocolate was being transported to the Munich museum. Gronk and his mercenaries got into a big brawl with the Cooper Gang on the train that was transporting the chocolate. Unfortunately, they were no match for the Cooper Gang and were all knocked out during the fight, effectively letting them escape with the chocolate.
Gronk and his team also traveled to Australian Outback with Carmelita as she pursued the Cooper Gang. They were seen attacking Sly as he climbed giant Carmelita to remove the Mask of Dark Earth from her face. Once the mask was off, Gronk's soldiers destroyed it, which resulted in an explosion that killed several of them.
Gronk and his team later appeared at Kaine Island to attack Dr. M's mutant. However, their efforts were not enough to stop the monster, and they suffered a high number of casualties in the battle. Gronk's fate remains unknown.
Relationship with Carmelita Fox
Carmelita's attitude to Lt. Gronk and his hired mercenaries seems rather ambiguous at most. On the one hand, she is stern with them and seems rather unmoved when any of them are hurt or killed. On the other hand, she will compliment them on a "job well done" and "fighting with honor" if they do as they were hired to do. She also seems to be more resilient to damage than any of them.

- Gronk and his mercenaries appear to be eastern European based on their accent.
