What it means: "You are treating me with contempt and disrespect due to the responsibility/cost/stress/etc that comes with raising me, something I had no fundamental say in. A choice you made has led you down this path, and now I am being blamed for the consequences of your actions, and I don't appreciate it."

Hoo, boy DO I? i only have a... *checks*... Wow, a 34K word document full of them.

I have become very attached to the version of him I have built up in my mind for the purpose of a story where he ends up in a relationship with Michelangelo, so the below headcanons will be very specific to this version of him which lives in my head. He has become a bit of an OC at this point hahaha

Some spoilers for the fanfic I may or may not ever post, lmao

Civilian name is Thelonius "Theo" Sylvester

He/him, omnisexual, 19 years old, Certified Grandpa's Boy

Leftie (this one is canon! and as a fellow leftie I take it very personally) - Mikey will often laugh at the trails of ink that line the edge of his hand when he’s been writing for extended periods

Youngest of four children. Has a fraternal twin sister. Grandson of Silver Sentry, or Grandpa Sentry as he has always called him growing up

First year undergrad student at University of Manhattan’s Hamato College of Engineering. Majoring in Sustainable Robotics, Automation & Mechatronics (SRAM)

Has been moonlighting as Turtle Titan since he was about 14, joining his grandfather on patrols in an outfit very reminiscent of TT’s original red hood getup. After his grandfather’s death he rebranded, feeling a sense of responsibility to carry on protecting the city as Sentry did

Theo and Sentry used to get breakfast together after a busy night of patrols and it is a memory that has stuck with Theo - he hasn’t properly sat down and enjoyed a fry up since his grandfather’s death because it is something he associates so closely with Grandpa Sentry

He has a very basic grasp of the Triceraton language (Triceratonese? Triceratese? Triceratonian?) because his best friend is a Triceraton named Xanthy and she has taught him a few things + he strikes me as the type to enjoy the 2105 equivalent of duolingo. He is also friends with Britney Alexander, the human reporter from Invasion of The Bodyjacker. The three of them attend the university together

Following the FF Turtle Titan episode, he and Michelangelo start going on more patrols together, but they discover each other's civilian identities by chance through a dating app. Things just... Keep happening, after that <3

I would describe him as a 20th Century Guy In A 22nd Century World. Because of his close relationship with his grandfather growing up, he is nostalgic for the things Grandpa Sentry was nostalgic for - old music, old movies, old clothes. He definitely frequents the cinema the Earth Appreciation Society meets at. He definitely dresses more old timey than his peers. He is maybe the only person in 2105 not judging Darius Dunn for the Evil Victorian Viscount aesthetic he has going on. He is definitely one of those teenagers who posts shit like "I was born in the wrong century </3". Not sure if that last part is a joke or not

He plays Helix and isn't terrible at it, although not as obsessively as Mikey. He also doesn't have as much purchased DLC as Cody because he is not a teenage billionaire

He has never been to the Battle Nexus before but is fascinated by the concept and is very excited at the idea of someday seeing his boyfriend's statue in the pavillion of past champions. If they ever go, it's a guarantee that they will make out in front of it. In my mind he would make it past the first round but then lose embarrassingly quickly in the second round

Gets along well with Master Splinter and Leo, can gab with Don all day long over robotics, and while he finds it more difficult to get along with Raph due to his more vocal disapproval of superhero work, the two of them do have a shared appreciation of motorcycles, models which are vintage to Theo but way beyond anything Raph has seen back in 2005

He and Cody have met prior than being introduced through the turtles but don't know it - they have been rivals in auctions for Turtle Titan merchandise for the last three years and things got a bit petty and heated. In person they get along great and Theo ultimately ends up with an internship at O'Neill Tech after Darius is removed from the company and Cody is given more control over hiring decisions. Some of it is down to his talent and enthusiasm for robotics, but I will also say what we're all thinking - nepotism triumphs again!

There are probably more things I haven't mentioned but these are just the ones I can think of from the top of my head lol

Things which remind me of him are tagged under turtletitanshipping, mikeytheo or theoposting

I also have a tag on my art blog. And also a spotify playlist.
