Funko Pops are highly collectible. People all over the world collect characters from their favorite movies or TV shows to show off to all their friends. You just need to make sure to keep them in the boxes to return their value!

However, Funko Pops can do so much more than bring joy. They can also spoil big upcoming releases by showing off a character that was supposed to remain a secret. In some cases, the Funko Pop ruins a big, important moment in the movie. Here are 10 Funko Pops that spoiled movies. After you read this, maybe you should wait until after a film comes out before buying your next figurine.

Captain America: Civil War

There are two major fights in Captain America: Civil War. The airport fight was a ton of fun, and it was even better with the reveal of Scott Lang turning into Giant-Man. Or at least, it would have been thrilling had Funko not released an Ant-Man figurine called Giant-Man. Collectors knew well in advance Lang would turn into a giant. It wasn't necessarily the biggest surprise of the movie, but it was a fun bit to witness. We suppose this also would've been spoiled for people if they looked at the concept art beforehand.

Justice League

Superman sacrifices his life at the end of Batman v. Superman: Dawn of Justice. We all saw that dust floating just over his coffin in the final moments, so we all assumed he would be back at some point in Justice League. Still, it doesn't excuse Funko releasing a Superman figurine explicitly for Justice League. It proved definitively the team would need to resurrect Superman to defeat Steppenwolf, and at that point, all the tension from the movie really goes away. After all, it's not like they would kill Superman in two movies back-to-back.

Alien: Covenant

Alien: Covenant was Ridley Scott's way to bring the franchise back to form after the highly criticized Prometheus. No matter what, when you are watching an Alien movie, you can expect most of the cast to die.

It was still rather unfortunate to see a Funko figure depicting one of these deaths in detail. Christopher Oram is the Chief Science Officer on the Covenant. He isn't the most important character of the film, but the Funko figure still shows him meeting his demise on the wrong end of a facehugger. You would think as a Science Officer, we would have enough common sense to stay away from strange alien life. Here's hoping one day soon we'll get to see Alien: Awakening.

Pirates of the Caribbean: Dead Men Tell No Tales

Pirates of the Caribbean: Dead Men Tell No Tales was the last movie in the franchise, and hopefully, it will be the last one for a while. Before the movie was released, everyone was wondering whether Orlando Bloom would return to his role as Will Turner. At World's End left the door open for him to return, and the movie did end up using him. Unfortunately, the big reveal was spoiled in a Funko Pop labeled "Ghost of Will Turner."

Thor: Ragnarok

As soon as it was revealed the latest Thor movie would revolve around the Ragnarok storyline, fans assumed Surtur would appear in the film. Not only did the Thor: Ragnarok Funko Pop reveal this, it also showed Thor carrying Surtur's head. There's actually much more to the movie, considering Surtur only appears in the very beginning and very end. Perhaps this is less of a spoiler and more of just a reveal of what happens in the first five minutes of the movie.

How To Train Your Dragon: The Lost World

The How to Train Your Dragon trilogy came to an end in 2019. From the trailers, we all knew Toothless was going to meet a Light Fury. The film had plenty of awesome moments, but none were as touching as the very end when Hiccup allows Toothless to leave with his new love. Most everyone could have guessed Toothless would live happily ever after with his new lady dragon, but Funko revealed all in a set of figures showing their babies.

Captain Marvel

Jude Law's role in Captain Marvel was shrouded in mystery for the longest time. At one point, outlets even reported he would be playing Mar-Vell. When the movie finally came out, it was revealed he was actually portraying the villain Yon-Rogg.

Of course, Funko ruined the fun on that one. People may not have been able to tell it was Jude Law due to the mask, but comic book movie fans are pretty good at drawing conclusions.

The Predator (2018)

Not very many people saw the newest Predator movie. That means not a lot of people were probably bothered by a figurine showing off some of the plot development. The figurine in question shows Jacob Tremblay's character wearing the Predator mask. It spoils the Predators' plan in the movie to fuse their DNA with the genetic make-up of people with autism. This particular Funko spoiler likely flew under the radar because the movie tanked at the box office.

Shazam!

Billy Batson finally makes his big-screen debut in 2019's Shazam! This is the most recent film on the list, so if you still haven't seen it yet, you should probably keep scrolling. Back in February, Funko released the official Shazam! lineup, and it revealed something previously confirmed in reports. The entire Shazam family will make an appearance in the film to some capacity. The Shazam family has become an integral part of the comics, so it's great to see they'll have a role in the film and probably any sequels.

Avengers: Infinity War

We're not sure if this one should technically count as a spoiler. After all, the Funko depicts something that does not actually happen in the movie, but we were all so sure it would. The Funko Pop in question shows the Hulk busting out of Iron-Man's Hulkbuster suit. The problem is that this never happens. Bruce Banner never turns into the Hulk outside of the first five minutes of the film. We all thought we got a huge spoiler, but instead, it was a major red herring.
