This ambiguity about the ronin’s identity is further shown in an Instagram post by the_turtles_lair. They claim the creators of the The Last Ronin commissioned the drawing of one Turtle using all four weapons making it hard to know which one. I don’t know for sure how authentic the commission is, but it still shows people’s interest in the ronin’s identity.

During the video by THE OLD TURTLE DEN, I noticed that the ronin is seen with Leo’s swords, Donnie’s staff, and Raph’s sai. Mikey’s nunchaku were probably there, but I didn’t see them. However, it got me thinking that maybe the ronin is Mikey. 

He could be carrying the weapons of the others in order to honor them. If he was, there would be no reason for him to bring his own since he is alive. Plus, Mikey is the goof-off and youngest; he might be carrying them in order to be like the others. Leo’s the disciplined leader, Donnie’s smart, and Raph is the muscle/fighter/protector. You can see from the samples in the video that the ronin comes across with Raph’s typical gruff personality.

Mikey is the party dude. He’d always had the other Turtles or their allies to fall back on–he could be the goof-off–but now that they are gone, he sees that his surfer-dude philosophy isn’t beneficial. He has to step-up and mature, but he isn’t sure how so he imitates the others.

There could also be some survivor’s guilt, especially if his goofing off is what got everyone killed in the first place. He wouldn’t want to be the party dude anymore.

(Or it could be some new Turtle we’ve never seen before and they are just honoring the Turtles by using their weapons.)

Personally, I hope the ronin is Mikey because I think it’d be a great way to explore his character. He is always portrayed as the party dude so let’s see how he reacts to being alone: having to be the leader, having to be cunning, having to deal with loss and anger. 

Also, I’m tired of Raph seemingly always being the lead character. Just like DC seems to focus on Batman and Marvel focuses on Spider-Man and Wolverine is the lead in X-Men movies and events, I feel like they focus too much on Raph. There are three other Turtles with their own personalities and stories. I think they’d make interesting stories if put into different situations.

What are your theories? Who do you think is the ronin? Let me know in the comments below.

Until the next wormhole…thanks for reading!
