Which hero will not survive "Avengers: Endgame" on April 26? Close watchers of the Marvel Cinematic Universe (MCU) are already expecting at least one of the original Avengers -- maybe more -- will die in the finale.

Betting sites are putting out their odds. Bovada has a number of prop bets not only on who will be a goner, but how much money the film will make.

It's important to remember that a number with a negative sign in front of it means this is the favorite -- the outcome the casino thinks is most likely to happen. Think of it like going to the doctor's office. If you test negative, it's usually a good thing.

Do you think "Avengers: Endgame" will make over or under $257,698,183 in the U.S. and Canada on its opening weekend? As of April 9:

But which original Avenger dies first? According to BetOnline as of April 3, Captain America is at +100 followed by Iron Man (+150), Thor (+700), Hulk and Hawkeye (+900) and Black Widow (+1200). Scarlett Johansson is getting her own Black Widow movie, after all.

One more bet to look at -- who is the one to kill Thanos? A theory going around is that it could be someone you least expect -- Ant-Man. That theory doesn't seem to be popular at Bovada, which is listing it as +300 that Ant-Man kills Thanos and -500 that he doesn't.
