Damon's gravestone does not exist within Veronaville, so he can't be made playable without the use of hacks. As a result, the only indication of Damon's existence is provided by the family tree of his descendants. According to his SimDNA in SimPE, his hair was blond before it turned grey.
Damon has no memories of his wife, and although he has the memory of doing WooHoo with Mystery Sim, he doesn't have the memory of Elvin's birth. So basically apart from the WooHoo memory, he only has Create a Sim memories. Damon has no skill points or personality points, and if he is resurrected with hacks, he will have a random set of interests.
Damon is a Greek name that means "to take or subdue".
