Mark Jarvis is a character in Friday the 13th Part II, played by Tom McBride.
Mark is wheelchair-bound but still likes to keep fit. He plays video games with the other guys and gets the attention of Vickie Perry. While they get to know each other, Mark tells her he doesn't plan to be in a wheelchair his entire life. The two eventually kiss and Vickie left to freshen up. Mark went outside to look around. Unbeknownst to him, Jason Voorhees was behind him and he killed him by slamming a machete into his face, the impact sending Mark hurtling down a flight of stairs.
Although Mark has the last name of Jarvis he is no relation to future protagonist Tommy Jarvis.
