Halloween Costume Guide
Pietro Maximoff’s job in Age of Ultron is to be the Avenger who dies, which he does in the film’s final act with the line “You didn’t see that coming?” as his last words. The wig is what makes this Halloween costume work or not work. The film, directed by Joss Whedon (Wikipedia), has a large enough MCU following that fans will place the costume; anyone who skipped it will see someone in grey athletic wear.

The wig is what people clock first, and if the color is more platinum blonde than silver-white, the costume reads as a generic speedster or, at worst, Thor trying to run somewhere. The shirt and pants need to work as a matched athletic set; if they look like two unrelated pieces that ended up on the same person, the look breaks apart before the wig even registers. The fingerless gloves are not just a detail, they are what signals that this is a deliberate costume and not workout clothes that never made it back to the wardrobe.
The first time Pietro and Hawkeye meet properly in the field, Pietro catches one of Barton’s arrows mid-flight and dismisses him in about four words. The second time, Hawkeye is mid-monologue in a barn about the absurdity of fighting supersonic people with a bow and arrow, and Pietro runs through the background to make the point for him. The third encounter ends with Pietro in front of a Quinjet’s guns saying “You didn’t see that coming?” as his last words to Barton. He is delighted about it right up until he isn’t.
Order the shirt with a return option
Silver-grey in online product photos can arrive as pale blue, slate, or something closer to white depending on the manufacturer. The color has to read as silver-grey under indoor party lighting, not just in daylight. If you get this wrong, the whole costume shifts to generic athletic wear regardless of how good the wig is. Order from somewhere with free returns, or check the shade in person if you can.
Use the exit line early in the night
“You didn’t see that coming?” is short enough to deploy in passing without stopping to explain who you are. It works best right after something unexpected, like walking into a room or appearing behind someone mid-conversation. It either lands and the conversation starts, or it doesn’t and you move on. One line doing the recognition work beats two minutes of Marvel plot summary at a loud party.
Couples Idea
Excellent twin pairing with immediate visual contrast. Pietro’s silver-grey athletic build against Wanda’s red and black reads as a matched unit to anyone who has seen the films, and the sibling bond gives the pairing actual weight. You are not just standing next to each other. Most MCU fans will place this without needing an explanation.
Duo Idea
Strong meta concept if your audience is deep into the MCU. One person dressed as the Aaron Taylor-Johnson version and one as the Evan Peters version works as a joke about WandaVision casting a fake Pietro to manipulate Wanda. At a general MCU party, people will see two people in silver wigs and assume one of you got the costume slightly wrong. At a crowd that has watched WandaVision, it lands.
Group Idea: Avengers Squad
Excellent group with no explanation required at any party. Every costume in this lineup is independently recognizable, and the visual range across the five keeps anyone from blending in. Quicksilver is the only one who needs a wig to read correctly in a group photo, which is a manageable ask.
Group Idea: Iconic Super Speed Characters
Might work, but the visual range across this group is significant. The Flash is a full red suit. Sonic is a blue hedgehog. Dash is a child in a red bodysuit. Knuckles is a red echidna who is not primarily known for speed, and his fans will tell you that for the rest of the night. Quicksilver is in grey athletic wear with silver hair. The theme holds together if everyone commits to “we are all fast,” but plan on explaining the concept more than the individual costumes.
Most of this build can be thrifted. Grey and black athletic separates turn up constantly in second-hand stores. The one item worth buying new is the wig, because thrifted wigs are unpredictable and the hair color here is too specific to risk it.
Pietro is cocky, fast, and slightly condescending until he decides to respect you. At that point he becomes fiercely loyal and will step in front of a Quinjet minigun for you. The range is manageable for a few hours.
Start with the silver-white wig. Without it, the grey athletic wear reads as workout clothes. Add the silver-grey long sleeve shirt, black tactical pants, grey fingerless gloves, and grey running shoes. The wig is the item that tells people who you are.
Quicksilver died in Age of Ultron in 2015 and has not appeared in the MCU since, so recognition depends heavily on how closely someone followed that film. Dedicated MCU fans will place it. At a general party, expect “cool speedster” more than “that’s specifically Pietro Maximoff.”
Two stand out. His last words to Hawkeye: “You didn’t see that coming?” It is his signature taunt across the whole film, delivered one final time as he died. The other: “Be strong, sister. It won’t be long before we have the power we need to fight,” said to Wanda before the two of them agreed to HYDRA’s experiments.
Aaron Taylor-Johnson played Pietro Maximoff in Avengers: Age of Ultron (IMDb). He also appeared as Kick-Ass (2010), Ford Brody in Godzilla (2014), and Kraven the Hunter (2024). In the separate X-Men continuity, Quicksilver was played by Evan Peters across several films and later appeared in WandaVision as a fake Pietro used by Agatha Harkness.
He stepped in front of Quinjet minigun fire to shield Hawkeye and a civilian child during the Battle of Sokovia and died from his wounds. Pietro was twelve minutes older than Wanda and 26 years old at the time. Clint Barton named his newborn son Nathaniel Pietro Barton in his honor.
No. The alias appears in marketing and official materials but is never spoken in the film itself. Characters refer to Pietro by name throughout. This is a useful detail for winning arguments at parties where everyone is dressed as an Avenger.
Two completely separate film continuities, two different actors. Aaron Taylor-Johnson’s MCU version dies in Age of Ultron and has a Sokovian origin tied to HYDRA and the Mind Stone. Evan Peters played the X-Men version across Days of Future Past, Apocalypse, and Dark Phoenix, then later appeared in WandaVision as a fake Pietro used by Agatha Harkness. The two versions share a name and a power. Nothing else.
