Mr. Lukens enjoys taking photos of things to later show to his niece. He is also an aggressive advertiser who likes to catch his clients unaware before ensnaring them into a sale. He is also very arrogant.
Although Bob Lukens is a man, he works for the Enemy. He gave Max a replica of the Topkapi Dagger for his birthday. This lead to the discovery of his alignment with the Enemy. He escaped when the members of Rowan tried to capture him as he had many allies on his side.
