The objective of this challenge is to use an emote inside Stark's workshop and, luckily for you, this is a very simple mission to complete. First, make sure you have donned Tony Stark's costume when visiting the locker, since the challenge cannot be completed by the other characters. At this point we suggest you start a game in Team Brawl mode, in which the number of players is reduced and there is a greater chance that the area you are about to go to is isolated and that there are no annoying Stark Robots: your target is in fact the Stark Industries, the point of interest in the North of New York. Land in the area and enter Tony's laboratory, which is the large room with all the armor of the famous character inside: this is located to the right of the entrance and is also accessible from the outside by destroying with pickaxes the garage door (below you will find a map with the exact place to reach above indicated). Then enter the room, which in Team Brawl is not protected by a boss, and run any emote to make Tony transform into Iron Man. From now on you can run the character's integrated emote to make him wear armor and repeat the same procedure to have it removed.
