The technological mastermind behind the entire operation. Irritated that her brilliant Wakandan tech is dismissed as "toys," she channels her frustration into weaponized hacking. Shuri is the one reprogramming JARVIS, overriding Stark’s biometric locks, and upgrading everyday household items with vibranium-powered structural anomalies.

The resident hothead and hype man. Johnny is entirely here for the clout and the drama, thrilled to finally have an audience that appreciates his theatricality. He uses precision heat manipulation to warp everyday objects, overheat Tony's coffee precisely when he goes to take a sip, and create strategic smoke screens for quick getaways.

The anxious genius of the group. Peter’s guilt over the chaos is constantly at war with his desire to be taken seriously. He uses his wall-crawling and high-tensile webbing to rig elaborate ceiling traps, while his Spider-Sense serves as the ultimate early-warning radar to help the team escape just seconds before Tony or Fury walks into the room.

The unhinged wildcard and heavy artillery. Wade doesn't care about respect; he just loves the smell of property damage and a broken fourth wall. He acts as the team’s chaotic distraction, willingly taking the blame for minor pranks to hide the much larger, highly coordinated tactical strikes the kids are executing.

The overqualified tactical advisor. Natasha joins the kids purely because she finds the veteran heroes' arrogance exhausting. She provides the crew with classified blind spots in S.H.I.E.L.D. security, teaches them how to leave zero forensic evidence, and maintains a flawless, deadpan poker face while watching Tony lose his mind.

A paranoid, sleep-deprived genius on the verge of a breakdown. Tony views the pranks as a literal security breach and an insult to his intellect. He is taking the "bathroom lockdown" personally, treating the phantom mastermind as a high-level threat. He is obsessively analyzing JARVIS’s code and upgrading security, completely blind to the fact that the tech is coming from his own team.

The exasperated dad trying to maintain military order in a house full of chaos. Steve treats the pranks like a tactical psychological warfare operation. He tries to host team meetings to "discuss the breach," but his rigid discipline is useless against invisible opponents. He is mostly just confused by the modern humor, trying desperately to understand memes and viral trends.

The double agent who is absolutely loving every single second of this. Officially, Clint is helping the veterans hunt the culprits. Unofficially, he is using his stealth and trick arrows to pull off his own side-pranks, completely muddying the waters. He uses his vent-crawling skills to frame other veterans, gleefully blaming everything on the mysterious "mastermind."

The hyper-vigilant soldier who is entirely too stressed for this. Bucky’s tactical assassin training is completely useless against itching powder and modified vibranium. He is constantly on high alert, checking corners for tripwires and treating the kitchen like a minefield. The absolute lack of logic behind the attacks is driving his structured mind completely crazy.

The boisterous god who thinks this is a magnificent test of warrior spirit. Thor doesn't understand the nuance of modern tech pranks, but he respects the chaos. He laughs boisterously whenever Tony gets locked out of a room and views the phantom mastermind as a worthy, invisible foe.
