Simon is a zombie appearing in The House of the Dead. Found in the first two stages, he is the first muscular-type enemy encountered. He returns in House of the Dead: Scarlet Dawn having a different appearance but the same method of attack.
Simon is a pale-skinned, shirtless muscular zombie with glowing white eyes, dark hair, and gray pants. His left arm and portion of his upper chest have exposed muscles.
In his Scarlet Dawn iteration, he appears more greenish pale than before and has red eyes. The muscles on his right arm are more green compared to his skin. This is likely due to being incubated in biochemical liquids altering his muscular system. It also gave him increased health, as opposed to his first creation, and slightly thicker skin suiting him as armor.
Like other muscular zombies (Gilmore, Harris, and Robert), Simon dies in two shots to the head, but can otherwise withstand several bullets to the rest of his body. He attacks with a shoulder strike, but can also throw barrels and oil drums from a distance.
In the second chapter, a Simon attempts throwing a civilian at the player. One can potentially lose up to two lives here: accidentally shooting the civilian costs one life, and not killing the zombie in time costs another from an unavoidable throw attack.
He's seen accompanying other creatures during the outbreak in Scarlet Dawn. Not much has changed from his offensive patterns from the first game.
