Adam Palomino - Give him abilities that helps with the car. He seems to be the type of guy to work on cars. One ability could be a once-per-game instant car start if the car was disabled by Jason or an environmental crash.
A.J. Mason - "Red Herring" - Activating this ability will allow you to place a false noise signal that lasts 1 minute unless it gets destroyed. It can even be place in the wardrobe or under the bed.
Brandon "Buggzy" Wilson - I like the previously posted idea of him being unable to die if he survives 18 minutes, so lets add that to this list.
Chad Kensington - "The 1%" - The Chad player receives a 50% bonus to total earned XP for that round.
Deborah Kim - "Engineering" - Allows her to repair electronics in silent. Jason will NOT be notified of failure of repairs and/or the repairing process.
Eric "JR" LaChappa - We can give this guy the one-time instant repair as requested by others.
Jenny Myers - "The Final Showdown" - If you are the last player (at the location), other than Jarvis, if you knock Jason down or stun Jason, you "kill" Jason (but the XP isn't worth as much as the sweater kill). The stunning condition will require a minimum of 5+ accumulated Jason stuns through the match from any player(s). Jenny matches the type of movie character to kill the villain at the end.
Kenny Riedell - "You Killed Kenny" - If a Kenny dies, Jason will appear on the map for 30 seconds.
Tiffany Cox - "Time to get away" - Once per game, Tiffany can auto-break from Jason and run away without making noise and/or showing up on the "sense" ability. Those effects lasts 10 seconds. On the auto-break from Jason, Jason is NOT stunned.
Vanessa Jones - "Teleportation" - Like others said before, let Vanessa teleport throughout the map. Give this a cooldown between uses.
