Here are the PL Miraculous redesign. Some info under the cut. I'll go into more detail about the miraculous in a difference post.
Nino / ConShire
Horse Miraculous, I chose to give Nino the horse because in PL Nino feels like he failed Marinette as a friend and Ladybug for failing to protect the miraculous that Ayla and Chloe "lost" during the battle against The Beholder. He wishes he could just be there for his friends.
Color pallets, The Canon horse Miraculous design is... Something. People had explained why it's bad. I won't explain it but to avoid something similar I shake up the color design. Pegasus's design is a lot of dark browns stacked on top of each other. I make ConShire's pallet of richer browns and gave him a silver accent color. His design is a mix of horse jockey and music conducted.
His name is a mix between Conductor and the shire horse.
Kagami/ Ouro-Hydra
Snake/ Dragon miraculous, Kagami is a good fit for the dragon. I can't deny that. As for the snake, Kagami is a perfectionist so she would be good at resetting to find the perfect outcome.
Color Pallet, This was the worst. The design was easy coloring was hard. Trying to mix red and green was a bitch, even now I'm not too happy but can't find a better alternative. Her design is a mix of just armor and her original design. Her horn changed shape and places and gone with the mask and in with the scales.
Ouro-Hydra name is a mix between Ouroboros and Hydra. Both unending mystical creatures.
Marc/ PoetiKit
First things first his first design was ass.
Fox Miraculous, Marc is artistic. His imagination would be perfect to craft illusions. We don't know much about Marc in Canon, but I do imagine that's he's pretty shy and insecure. In the Painted Lady the reason he was akunatized was because Lila trick Nathaniel into believing that Marc plagiarized her and Nathaniel torn his writing. Liliavalso outed Marc as having a crush on Nathaniel, because of this Marc was homeschooled. This was a rare case where Lila did get in trouble. Marinette reached out to Marc and the bonded over being bullied over Lila (Marinette didn't share everything) and bring LGBTQ+.
Color Pallet, His first design was ASS! Once again not much is known about Marc, I had too much freedom. His outfit is a mix of his normal ware and clothes that I think of when I hear rave, but PG. I wanted him to have a cool but simple design.
His name is a mix between Poetic and Kit fix.
Luka/ Turtle
Turtle Miraculous, LUKA IS A PROTECTOR! This dude has taken akumas for people! He is the best!!!!! Luka is a natural fit for the turtle. Protective, a natural leader, and strategic the perfect combo! In the Painted Lady Luka is everyone's big brother/ Nino boyfriend. He lets Adrien live with him after he runs away. (He moves out of the house bout after Kitty Selection kicks Marinette out and hires Lila with out telling him.)
Color Pallet, pirate mixed with Rockstar. I love his design whole heart. I really tried to make it look nothing like either Turtle design as well as Luka's normal design. I also threw the fuck it bucket out and said anything can be a design. I was bored of body suits. My only thing is I hate the color green so. I tried to keep the color simple, I think I didva good job.
His name is a mix of Turtle Shell and Rockstar.
