What are some of your favorite character relationships/dynamics in TMNT, and why? Is there anything that you particularly like seeing explored with them in fan works (art, writing, comics, etc)?
I don't really ship anyone from TMNT and it is SO HARD to pick favorite dynamics without listing them ALL, but to mention a few:
Disaster Twins are just so fun to watch. I love how they are competitive with one other but have such soft spots towards each other. They seem to just get each other and know the other's limits. I especially love how the fandom has interpretted their dynamic. Y'all, half the time I'm over here sobbing in the corner. They are so sibling behavior. It's special to have someone you are close to understand you so well. <3
✨️THE SASS QUEENS!✨️ I like to call them Banana Pancakes duo. They are just so sassy towards each other. It shows how comfortable they are with each other. I believe April is good for Donnie by calling him out and helping him with emotions, and Donnie is good for April by just being her best friend. She really needed one. Also, I love how they are always protective of each other. (This also just gives siblings.) They seem to get along very well, and I think they are very grateful for each other. <3
PB&J Duo are just adorable. (they remind me of my sister and me, especially when we were younger) I just love their dynamic! Donnie is so protective and supportive of Mikey. All the turtles have such a soft spot for Mikey, but something about Donnie and Mikey just warm my heart. I like how Mikey is like Donnie's little shadow and also helps him with emotions. I feel like Mikey genuinely just enjoys Donnie's company, and whether Donnie will admit it or not he enjoys being around Mikey as well. <3
Sunset Duo gives me all the feels. I believe whenever Raph is emotionally unstable, Mikey is there for him. And whenever Mikey needs someone strong, Raph is there to lift him up. Raph is like the foundation of home, and Mikey is the hearth. They care about each other so much, but also in order to grow they need to learn how to be more independent. It is hard having to be less reliant on someone you love, but you get to learn more about yourself as an individual. That doesn't mean you love that person any less. <3
I love fanfiction revolving around all of them when it comes to longer stories. (I May Be Invisible, But I Still Look Good by Dandy on ao3 has MY HEART! 💙 I recommend you read it if you haven't!) It's fun to watch how they work as a team and to see how their personalities/talents contribute. It is also nice to get those one-on-one moments. Of course, comics and fanart are my primary source of substance. Om nom nom.
Although, I would say Turtle Tots is my favorite form of TMNT. I love exploring ideas of when they were little.
Thank you for asking, this was fun!
