I thought it ironic that during Marvel's Civil War the SHIELD power suits were refered to as 'CapeKillers'. Besides the insanely antagonistic sound to something in hero vs. hero conflict.... Marvel has NEVER been one for Capes. Off the top of my head there was Thor (who was dead) Doctor Strange, Cloak and Moon Knight and none of them were really A-list.
DC I could see getting away with that with Superman, Batman, Robins. Dr. Midnight, Hourman, Captain Marvel... and lots of other characters sticking with the traditional looks... but Marvel? A very weird thing to call out.
