In the So You Joined L33T poster, it is shown that the crew is attempting to persuade more people to join their ranks.
Pictures of their masks have been seen in numerous posters persuading others to join the group. Towards the end, the first two in the series were seen repairing Tricky's Portable Improbability Drive after Hank was smashed through the wall. Shortly, Jesus Christ jumped down from the roof and shot both of them with his new .50 caliber revolver.
The A.T.P. agents played a more important role. About half of all the protagonist's enemies appeared to be A.T.P. agents. Although they are supposedly at a higher rank than normal l33t agents, they appear to be no more powerful, for they are killed just as easily. Since of that the Auditior grows weaker but it is good for him with the dead bodys he absorbs them and gets larger, and stronger.
- Even though they were really common in the later episodes of the Madness series, none of them were killed yet by Hank himself.
