Spoiler alert.

Idris Elba's Heimdall is Thanos' first casualty in Avengers: Infinity War. When the Mad Titan takes over the Asgardian spaceship, Heimdall is able to send Bruce Banner aka The Hulk to warn the Avengers team on Earth. This doesn't go over well with Thanos, who impales the all-seeing and all-hearing Asgardian. Now, it appears to be truly over for Heimdall.

"Gonna miss my guy...Heimdall...," read the tweet with a photo of the character.

Heimdall was introduced to the Marvel Cinematic Universe in 2011's Thor and played a large part in keeping the Asgardians safe during Hela's rule in 2017's Thor: Ragnarok. While many speculate the Avengers team will be able to bring back the heroes Thanos killed with the power of the Infinity Gauntlet, others have come to terms with the loss of characters who died before the last scene (Heimdall, Gamora, Vision, and Loki). 

"We made those deaths impactful emotionally, because you have an emotional connection with those characters and it’s difficult taking someone like Peter Parker and putting him in that position," co-director Joe Russo told students at the Iowa City High School in a recent discussion, according to the high school's newspaper. "So we try to complicate things emotionally because our job as storytellers is to tell the best story we can and make your experience as many emotions as possible when you watch the film. Because ultimately it is a- you’re paying money to go see it and if we can make you laugh, cry, happy, sad and feel catharsis- you get a lot more for your money than just laughing or just crying."

With nearly $1 billion from international box office sales a little over a week since Infinity War's release, we'd say the Russo brothers' plan is working.
