It is a question that has bothered fans of the Marvel Cinematic Universe since the shocking climax of Avengers: Infinity War, but it's now been confirmed that the Power Stone was the one that wiped out half the galaxy.
The events of the Russo Brothers' movie saw Josh Brolin's Thanos head off in search of the six Infinity Stones with the end goal of bringing balance to the universe with a snap of his fingers.
If anyone had questioned which stone is the most powerful, Avengers: Infinity War artist VFX supervisor Dan DeLeeuw told Inverse, “The Power Stone was blipping them out of existence."
Although it was hard to distinguish which of the Infinity Stones turned half the MCU (and even animals) to dust, DeLeeuw said his team put a lot of thought into how the iconic moment would happen. “All the Infinity Stones have their signature color and appearance as a visual effect,” he reminded audiences. “So the ‘blip out,’ we thought, ‘What would all the stones do to a person, blipping them out?’”
The stones may have been seen working in harmony to toss the Avengers out of the way as Thanos went for Vision, but it came down to just one being responsible for Thanos' rebalancing. While some of DeLeeuw's team championed the Reality Stone or the Soul Stone “because souls cease to exist, ” it was up to the Power Stone to deliver that killer blow.
DeLeeuw continued to explain how Infinity War settled on turning the characters to dust. "We had concept art combining all those things, and it was getting too busy. It became too complicated," he confessed. "It was stepping on what the actors were doing. So it became 'body turns to ash.' We peeled away all those layers and focused on that one [Power Stone], deciding how quickly it would consume someone, what pattern it would consume them."
Ironically, the Power Stone had the smallest role in the movie and had already been snatched from Xandar before the opening scene. That being said, the Power Stone's ability to pull a moon out of orbit should've been a sign of the energy bubbling inside it.
At the end of the day, the likes of the Soul Stone and Time Stone couldn't compete with the raw energy of the Power Stone. Fans may also remember the awesome power of the purple gem in Guardians of the Galaxy, so it makes sense that the Power Stone was the one that eradicated half of the universe.
A popular theory is that the Soul Stone could be the key to bringing back the fallen heroes, but if the Power Stone was behind Thanos' snap, what does this mean for Avengers 4?
