On the subject of Clint's costumes, Hawkeye is another character whom I'd love to see get one of the Russell Dauterman costume gallery variant covers this year!
Clint certainly has more than enough different looks to qualify!
- his outfit when he was in the circus, training under Swordsman and Trickshot
- his original Hawkeye outfit
- his classic Avengers era outfit
- the miniskirt costume
- the long-sleeve outfit he wore when the WCA started
- the bulletproof armour suit
- the variant costume he had in his 2nd miniseries (the one just after Mockingbird 'died')
- the 90s-style costume he wore around the time of "The Crossing"
- his "Avengers Forever" look which was part of his Goliath costume, without the harness and using bow and arrows.
- his first Thunderbolts-era costume
- the new costume he got after he returned to the Avengers post-T-Bolts; the one with the one armoured sleeve
- there are at least two or three different versions of his Ultimates/MCU-style shades-and-tactical gear outfit.
- current T-Bolts version costume
Plus there are the actual Ultimates versions. Heroes Reborn versions. The "Bowman" variant from AVENGERS vol.3 #2-3. His "Golden Archer" identity that he used for one issue. He was Captain America for a single issue between Steve Rogers' death and Bucky taking over as the new Cap. There were two issues of WCA where Clint wore a Goliath costume that was orange and brown instead of red and blue due to colourist error. And for just fun they can throw in the "Hawk block" look from Fraction's run--naked Clint with a classic headshot as a modesty censor.
Any others?
