Shouldn't Leonardo pair up with Mona Lisa?
 

Maybe not as a couple, but they could be good friends.
Wouldn't it make sense to have Leonardo befriend Mona since Leonardo da Vinci painted the Mona Lisa (a bit of an in-joke)?

Raphael was probably easier to pair up.

Funny you should say that, Because Leonardo has been paired with Mona Lisa, in a couple of fan art at DA before.

I see the logic there. I doubt we'll ever see Mona Lisa ever again though...

All is right in the world.

Mona Lisa is sort of like Mondo Gecko, Mutagen Man and Muckman, people don't care for the characters as much as the idea of the characters.

Except for the hardest of hardcore fans, that do care about the characters.

Just based on name? Meh. If she'd stuck around they'd at least have known each other still.

The hardest of hardcore are the 1% of the 1%, I seriously doubt that many people care about Mutagen Man or Muckman for those single episodes they appeared in. In the case of Mondo it seems the excuse both Nick and IDW had for bringing him back was to have a character with FW/Movie Mikey's persona without the risk of having Mikey himself look shallow and outdated. The fact they cast Robbie Rist in the role enforces this idea.

As for why Mona Lisa won't return, the role people want her to play is filled out by Alopex in the IDW series and the Nick series won't have her because Ciro has some really weird ideas about girls in cartoons.

a role that was previously filled by Ninjara in the Archie series comic, Like it or not, Alopex is the Ninjara of the IDW comics.

I love Muckman & Mutagen Man, personally. Their toys & OT episodes were awesome, so I am happy to have them return.

Indeed. I don't really care for her, so why would I root for any instance of her returning?

She was a physics student, she'd probably would've gotten along with Donatello well.

Regardless, I agree, more people are interested in the idea of the character, not the character herself.

I agree or Mikey. I think if anyone Leonardo should be paired with Venus. Now before everyone screams and kills me I present exhibit A

Then April would be jealous seeing Donnie hanging out with her.

How about... no pairing whatsoever? That works for me.

You show a real disdain for the character, which is no surprise.

I think Mona Lisa would be a good character if done right, And not overly sexualized

My vocal dislike for the character aside, why are so many people hung up on playing matchmaker with a bunch of fictional characters? What about a clan of monster assassins makes you want to push two heads together & say "now kiss"? I don't get it. Romance has no place in the TMNT besides Casey & April's situation which is turbulent at best.

I'll probably get a lot of flack for this.

I actually like all three of them, Mona Lisa, Muckman, and Mutagen Man from the FW series. They were all really cool to me. I can see how pairing Mona with Leo would be a funny tongue-in-cheek pun, but he already had a thing going on with Lotus Blossom (now that is a character I didn't care for).

Still, I kinda liked how Raphael and Mona were paired up, I thought they played well off of each other in that episode. I always kinda wanted her to appear in at least another episode or two, but I wouldn't want there to be any serious love story arc going on between her and Raph. Stuff like that was not meant for the FW series IMO.

I'm not a fan of pairings or shipping or whatever, just because a female character is utilized, I don't know why people immediately start playing mutant match maker
