Last Night on Earth is a zombie-themed modular board game created by Flying Frog Productions in which players are split into two groups: Heroes and Zombies. The game objective changes based on which of several different given scenarios has been selected for play. The game takes great care in its thematic elements to achieve the look and feel of a zombie movie, causing the game to exhibit some of the most classic horror movie tropes
Subverted in some scenarios like "Burn Em Out", where they're explicitly needed to blow Spawning Pits sky-high, and when one can reliably take out a group of zombies without fragging other Heroes or mission objectives. Gasoline can also be used as, well, gas, for objectives requiring fuel, or for items like the Chainsaw.
Crazy-Prepared - His "Resourceful" ability can be seen as this, as he can pick two cards from the Hero deck, and chose which one to keep (discarding the other one)
Billy, The Sheriff's Son
Fragile Speedster - Automatically adds one to his movement, but is can only take two wounds before dying (he can automatically heal one per his 'Youth' ability).
Killed Off for Real - As confirmed by Sheriff Anderson's bio in the Timber Peak expansion. Considering his less-than-great ability and that Alice from Timber Peak has a similar but improved one, the odds of us seeing Survivor Billy seem.. unlikely
Sally, The Highschool Sweetheart
Born Lucky - Her "Luck" ability let's her force a zombie to re-roll fight dice of her choice.
The Big Guy - of the original heroes, despite just being a teenager - his "Tough" ability let's him win fights that are a tie, and his "Blitz" ability allows him to fight a zombie without automatically stopping his movement
In Harm's Way - her "Daring" ability lets her move through and search buildings that are "Taken Over" by zombies, and her "Reckless" ability lets her draw a Hero card when she ends her move on a Zombie Spawning Pit
