When it comes to Tron, giving him an incredible—and official—suit that is one of his best looks. This is definitely one that should make a comeback.
The Quicksilver/Tron variant cover was featured on Avengers Academy #7, which has the creative team of Christos Gage and Tom Raney. The cover art was illustrated by Brandon Peterson. While inspired by Tron, the cover was released around the same time as its sequel, Tron: Legacy (2010). However, considering the Walt Disney Company owns the film and Marvel Comics, it is entirely possible for this to be an official outfit—it certainly wouldn't be the first.
Quicksilver's usual outfits have a tendency to look rather outdated or they just aren't very good in comparison to Marvel's other heroes'. This speedster first appeared in 1964, within X-Men #4. He has a lengthy history, but few of his costumes have been stellar especially compared to his sister the Scarlet Witch. His suits have ranged in color, from blue and grey to green and silver. The various shades of grey and silver are usually staples of Quicksilver, which is fitting considering his name. However, they just don't give Pietro the punch he needs considering his comic history.
His most iconic outfit is likely his light blue suit with the bolt across the body. While this suit IS nice, it's outdated. Other suits replicated the zig-zag pattern with alternate colors applied to the rest of the body, but these are all almost the same design. The suit he used in the MCU isn't bad, but it's designed to look good on camera and to appear visually practical. It wasn't designed with comics in mind, even if it looks fine overall. The Tron suit is similar enough to other suits to be recognizable given the bolt pattern, but it is also a stand-out from the rest. The glow actually matches his abilities and would likely visually emphasize his speed more, since he already leaves blurs in his wake and could also trail some remnant light behind him.
Most characters have a default suit they can always return to, or they get new suits that fit their current adventures. However, it wouldn't be unheard of for a variant cover designed suit to actually be used—particularly in the case of Tron. Spider-Man was also featured in a Amazing Spider-Man #651, which had art by Mark Brooks. The suit was actually used within this comic run. His suit could glow multiple colors, including green and red. It is a stealth suit he debuted during a team-up with Black Cat, in which she does comment on him looking like "an ad for the new Tron movie." The suit also has an additional sonic dampening mode, "baffling ... everything from infrasonic to ultrasonic." While it is partially a gag, the suit was well-incorporated into the story and it is a rather good look for the Webslinger to pull out on occasion.
Considering that this Tron suit not only appeared in official Marvel Comics storylines, but that it also stuck around for a few issues, there's no reason Quicksilver couldn't use his version. Superheroes get new outfits all the time for a variety of circumstances and the speedster could definitely use a fresh, modern look. Marvel should definitely consider bringing back the Tron suit as an official costume for Quicksilver. After all, it worked out fine for Spider-Man.
