Ellis

Ellis is one of the four playable Survivors in Left 4 Dead 2. He's a goofy, beer-loving smart guy that likes to work with machines. According to Chet, he is "extremely excited" about everything, like managing to visit a concert and kill a lot of zombies, making him more of an optimist like Louis of Left 4 Dead, but like Francis, Ellis believes himself to be indestructible.

Official Description
Age: 23

Hometown: Savannah, GA

Ellis is a mechanic with a love of life, a firm belief in his own immortality, and the ability to treat any setback as a fun dare to impress his friends. Born and raised in Savannah, Ellis divvies up his time working at the local garage, hanging out with his buddies, and dropping by for Sunday dinners with Mom—why’d anybody want to live anywhere else?

Then the zombies had to go and spoil it. Now Ellis is looking for new things to occupy his time, and finding plenty. It turns out the zombie apocalypse is one big dare, and there’s no shortage of crazy stuff he can try to impress his new buddies.

Relationships with other Survivors
As of now it is a bit unclear what Ellis' disposition towards the other survivors is.
 * Coach: Coach and Ellis don't have much of an evident relationship. Coach will be sad when Ellis dies, and vice versa. They do seem friendly when they talk to each other, however. It is interesting to note that while in the hotel, Ellis refers to Nick and Rochelle as "sir" and "miss" respectively while he refers Coach simply as Coach, it's possible Ellis went to the highchool Coach teaches at, they also enjoyed Whispering oaks before the infection (though Ellis does even during the infection) and they both are fans of Jimmy Gibbs Jr. and the Midnight Riders.
 * Nick: Nick and Ellis do not seem to have a very friendly relationship. Nick openly insults Ellis in many separate occasions, and rarely compliments him. For that reason, Ellis doesn't seem to act very friendly towards Nick normally, but will say nice things about him, and seem genuinely sad when he dies.
 * Rochelle: Ellis has a fairly strong bond with Rochelle. It is also seen that Rochelle mildly treats Ellis like a younger brother, often being supportive when Ellis is in trouble. Ellis is quite sad to see her go, and they joke around throughout the campaigns.

Trivia
