At the end of the events of Channel Chasers 20 years later we see Timmy future kids, which are Tommy and Tammy Turner which coincidentally look like Timmy previous love interests this causes the fan base to theorize who the mother is . While looking through the series, writers, interviews, fan ideas, and some hints from his self Butch hartman it leave 3 candidates who likely the mother is.
Now contestant #1
His stalker/fan girl Tootie : Tho, an obvious choice throughout the fan base there is some good evidence for her being the mother and wife of Timmy, Tommy and Tammy Turner. One is the physical appearance of Tommy and Tammy like how Tammy has the same glasses like Tootie, the black hair from Tommy, the same eyebrows of and color of Tammy and for Tommy ,the nose of Tommy and finally the small pupils of Tammy. Those however the children do have similar traits as her it doesn't necessarily mean she is mother for two reasons and these two reason are
Timmy doesn't like Tootie romantically
Turner Family actually have all the same traits as her.
Timmy and Tootie relationship have been mostly one sided and unhealthy which doesn't really help in this case of scenario now does it ? (Sorry if that sounds biased or rude to you) Timmy in the series has never shown any type of affection to Tootie, besides from the live action movies mostly because he's not interested into her and she creeps him out by literally fan-boying and stalking over him. It became so bad to a point he must get restraining orders against her, numerous times also Tootie has been shown to force her, manipulative, stalks and even abuse Timmy to get his attention. (Ah ! True Love.)
Keep in mind that Timmy won't forget these memories in the future, he will only lose the memories of Cosmo and Wanda the experiences he had will never leave. Those Timmy have shown disdain to Tootie romantically, he does have good chemistry with her under specific circumstances and he does care about her.
The Turners family genetics traits : Those the children Tammy and Tommy Turner do possess Tootie's physical traits but could be possibly that they have some of these traits from both sides of Timmy family. Examples : Tammy glasses could be a factor from Timmy mom because she wears contact lenses, also Pappy and Genturde do wear glasses but we don't know if it's genetics or old age. Tommy black hair and nose shape could come from Timmy dad's side. Tammy eyelashes could come from Timmy mom. Also Tootie lacks long hair so it could be possible Tammy is not her child.
Now contestant #2
2. His best friend Chloe Carmichael. Yes, her. Tho, a controversial character according to the fanbase it is possible for Chloe being the mother to Tammy and Tommy Turner. Timmy and Chloe relationship is actually one of Timmy likenesses and healthy relationships with a girl aside his Mother, Missy and Wanda. The relationship between the two them mostly platonic, those however they has been some hints of romance interest (that could be implied) like in the The Fairs Bears we see when Timmy turns back to normal from being mind control while unknowingly hugging Chloe afterwards we her smile when Timmy realizes he is hugging her or the time we see them holding hands in Fancy Schmancy and Chloe smiles and stares at Timmy and finally we see Timmy hugs Chloe (those could be taken as a forgiveness hug but Timmy never hugs girls beside his Mom or Wanda. Timmy and Chloe have shown deep care for each other. (Like the time Timmy protected Chloe from the return fair bears ,another time in the Return of the losers she shows concern and remorse over Timmy after fake death and finally both say they will miss each other if they move.)( The ship isn't perfect however they typically argue a lot but later on they became a whole better later on.) Edit: forget to mention they great chemistry.
For the physical appearance those, the children do lack most of her appearance beside the exception of Tammy hair there is answer for that, Chloe and her family are mostly made up by recessive genes like Connie red hair and blue eyes and Clark blonde hair and eyes. Which means it's not as likely those traits begin selected also the Turners are mostly dominate traits an expection being the blue eyes.
The only traits you could say that Chloe gives to Tammy or Tommy is her hair for Tammy ,black eyebrows for Tommy, the blue eyes for both and the way the kids are structured (Body). The other traits are likely from the Turners.
Butch hartman have commented on the relationship/dynamics on Timmy and Chloe saying this " Timmy Turner wouldn't love necessarily at first and maybe still a problem with it" This doesn't really dismiss the concept nor confirmed the ship
The only thing that is fishy is Chloe not begin around to watch over Tammy and Tommy because knowing how motherly she is, to a point she literally babysitted Timmy twice 😑 and also she literally was confirmed to be a professional babysitter so it weird they hire a babysitter and knowing how stubborn Chloe is sometimes, those Timmy dad was the same way with Timmy until some convincing from his wife (Abra- Castotphere) or maybe she have a job that requires her a lot.
There, really nothing that prevents this ship becoming cannon in the future however remember Chloe didn't originally exist during Channel Chasers but this is the future again so anything can happen. ( Also, there have been numerous retcons in the series to begin with.)
Now contestant #3
3. His First Crush Trixie Tang and this brings us to our final contestant. Yes, tho was Timmy's first crush (I guess Missy won the war) Trixie Tang has a possibility of being the mother of Tammy and Tommy Turner.
Through physical appearance there's not much to work but there are some key features she have to give to Tommy and Tammy. First of all, is her hair shape for Tammy, second, is her eyebrows for Tammy and the color for Tommy, third small pupils and tint color for Tammy and the way the kids are structured. For the possible answer for Tammy glasses we do see Trixie father wear glasses but we don't know if this is cause by genetics or old age.
Timmy and Trixie's relationship is probably the most interesting one but the least likely one because Trixie doesn't like Timmy romantically while Timmy does, well he used to (Missy took his heart in S9). Numerous times in the series we see Timmy trying drastic and desperate measures to get Trixie attention. (through wishes or physical)
While, Trixie and Timmy do have good chemistry under these circumstances and Trixie does truly appreciate him indirect when he does it but Trixie have signs why this relationship won't last long by showing:
Extreme attention and affection to Timmy if he not pay attention to her to point she attack and almost killing him
Selfish sometimes use Timmy to get what she want or getting popular
Cheats (technically not really cheating she will move on from Timmy if he doesn't something or less, like the time she went to Franics willingly)
And, finally not giving Timmy a chance sometimes numerous Trixie have shown not even trying nor cares to give Timmy a chance. (It really an apparented during the latter seasons.)
While it's not impossible Trixie being the wife to Timmy and the mother of Tammy and Tommy but the status on thier relationship it's not as likely.
So out of all the contestants it a tough call so I decide to rank each one
In my opinion( if Timmy thought about) then Chloe is one Timmy likely married to and for physical appearance for the likely Tootie mostly because Tommy nose and Tammy glasses and small eyes. As for Trixie she could be both but it's not as likely those I see her and Timmy as good friends .
Tootie: Likely the biological mother
Chloe: Likely the one Timmy marries
Trixie: Probably more likely a good friend to Timmy
Imagine if Timmy marries all 3 of them and also there, an unknown child to whatever corresponding mom. Ha, that will be funny hmm those will be interesting by a concept however ,but I doubt that ever going to happen.
Ship name: The Likely Trio
I wonder how the fan base is going to react to this if this concept becomes cannon ? What your guys thoughts ?
