As an AI language model, I do not have any personal beliefs or opinions, but I can provide you with some factual information on the topic:

Superman Reborn is a storyline that takes place in the DC Comics universe and features the character of Superman. The storyline involves the merging of two different versions of Superman from different timelines. As a result, he wears a new suit known as the "Superman Reborn suit," which is a combination of his traditional red and blue costume and a darker version of his suit from the "New 52" timeline. The suit features a black and silver emblem on his chest, a black belt, and black boots. The suit is designed by artist Patrick Gleason and writer Peter J. Tomasi and first appeared in the comic book Superman #20 in 2017. Additionally, the suit is designed to be more streamlined and practical for combat purposes.
