Lomez, who was portrayed beautifully by Armando Rabbi, is first discussed in 7:5 The Hot Tub. He did such a great job and lived such an interesting life that they brought him back for 6 more eps.
Lomez has either sold or traded many things to Kramer, such his hot tub and his stereo. He vacations in the everglades, which causes him to miss his yearly obligation of hosting a Jewish singles party, which he has Kramer do in his stead. He has power over Kramer when it comes to meetings, might be partially responsible for the death of his neighbor's cat, uses Port-a-Potties when he really needs to go, and likes talking about Jerry's personal life with Kramer, while he's in the shower.
The only thing you need know about Lomez is that he possibly has a son who is the head of the Van Buren Boys, whom he named after himself, which is not allowed, if he truly is a religious Jew.
