I would like to create a cosplay that is a mashup between link, from legend of zelda, and cyberpunk 2077. How can I adjust link's outfit so it fits in the cyberpunk universe?
A long trench coat with military style pixel camo (forest green/dirt brown) with a glossy plastic finish. The hem and accent color are fluorescent gold with a large Hyrule crest in the back. From the large pocket of the black leather pants dangle the chain of a grappling hook. Link wears large heavy boots colored in a in shiny lead paint.

The arrows in the quiver are reminiscent of ancient arrows from BOTW. If someone ask you why you carry arrows and bows in a cyberpunk setting, just let them know these are powerful EMP arrows.

May I suggest pink hairs like in link to the past. Don't forget the master sword. Some sort of lens on one eye reminiscent to Midna's helmet could add the cyber esthetic and be a nice touch.

The hardest part in my opinion will be to make the hat match. A valid option could be to just wear a classical link's hat and just pretend that's it in fashion in 2077. Or maybe if you want a more grim esthetic a gas mask turned upside down. Either green like the outfit or multicolor like the majora's mask.

Anyway, I hope you have a lot of fun with this inspiration for a Link cosplay. Don't hesitate to make personal changes to it as a cosplay is also a great occasion to let your personality shine trough the costume.
