Has Sari ever involved Crashstop in cool yet dangerous stunts? How did the creators react?
When Safetycrash was young Sari convinced them to let her fly in their cockpit. It ended by Safetycrash crying to Optimus about Sari puking and passing out inside and passenger joyrides subsequently being banned.
In the Crashstop sparkling with her creators happy together: When Crashstop was still small has Sari ever put small accessories like hats, sunglasses and mittens on Crashstop to make her look cuter and how did her creators react to that?
The in Safetycrash story with having her creators together how did Optimus's team and Sari interact with the sparkling?
They are trying their best but keeping in mind "Baby, it's too late for us" events are still canon its not exactly smooth. Especially not after Blitzwing joins.
Sari is delighted by Safetycrash and thinks she's the cutest but also kind of gross and weird. She basically treats Safetycrash like a plushie at first because she's a kid and doesn't know how to interact with babies that are not dolls. They have tea parties together and also Sari uses her like a bean chair sometimes when no one is watching because Safetycrash is warm and doesn't start crying like a human baby would.
Prowl takes caring for Safetycrash dead serious. Using his ninja skills to hide just out of sight and then the slightest hint she's getting upset appearing in a flash with just what she needs. He tries to distance her and Blitzwing in his mind and view her as her own being not guilty of what her creator has done and Blitzwing's actual presence is very much inhibiting this. She 100% gets tested on who she loves more of her sire or her uncle and they only stop this because she gets confused and cries.
Ratchet is "grampa with the cat he didn't want" core. He takes care of checking Safetycrash's health and making sure her firewalls are updated. When he is on babysitting duty he sits in a chair with her on the lap and falls asleep and she copies him. Very protective of her when Blitzwing is around, it makes his scars itch and he has to check on her more often to make sure Blitzwing hasn't stolen her away.
Bulkhead is oh so careful with Safetycrash and is constantly having to watch his pedes for Tiny Unpredictable Sparkling. He loves her so much and spends much time almost crying at her squishy face, delights in babysitting duty however can sometimes forget he is on babysitting duty and just put her on a booster seat inside his chassis and forget she's there until she throws up because he moved too much. Very much gives stressed overworked mom energy because he tries to do everything on his own as to leave Optimus open to doing 'more important things'. Puts himself between Blitzwing and Safetycrash very often because he doesn't really trust Blitzwing to be good for her but it's less hostile than the others because Bulkhead is at least open to them interacting in controlled ways.
Bumblebee is kind of mean spirited at first. He's intentionally not watching Safetycrash when he should and allowing her to get into dangerous situations. He gets chewed out by the others a lot for it and isn't put on babysitting duty alone. His hostility becomes worse when Blitzwing joins because it's a reminder to him that Safetycrash is what keeps Optimus trapped with the 'Con. I think he only cools down significantly after having made the poor choice to 1v1 Blitzwing and then being confronted by Optimus about it. After that he's very very awkward with her because he doesn't know how to handle babies.
Would Dubstep and/or Crashstop be able to live on Cybertron?
Yep! Dubstep is born in a time of peace on Cybertron so is able to go through life pretty unchallenged.
Crashstop is also a citizen of Cybertron but in her canonical timelines its mostly because of her parent being Optimus and because the Autobots are looking for flying units.
Me looking at the good timeline baby: Gee Crashstop! How come you get to have... Uh... [Does quick headcount of Blitzwing alters] four to sixish parents depending on how you count and whether or not that one joke comic is canon?
I have to say, including Bitz (My nickname for Blitzwing, the og, the other option in my mind was Blitzwing Prime aka BlitzPrime) as one of the parents is very funny.
It's more like 2 parents with Wings/Blitz/Zing/Liz sharing divided time between them that equal 1 parent.
If/when Crashstop is born in the "this was supposed to be a fling" timeline she is gonna have it sooooo good compared to the other versions of her. You know they're gonna wait until things are stable and safe and they know the have the time and space to raise a kid they're gonna be RESPONSIBLE about this she's gonna be so loved in an environment where it's safe to be openly loved by both her parents. She's gonna have the team as uncles who all love her (and Sari if girlie has a cybertronian lifespan lol. I think it would take at least a few centuries for everything to even out into a place where a lil warframe-civilian frame can grow up and not be constantly Going Through It) and aunt Liz as family and she'll have it great. Living her best life. No one is doing it like her (mainly because shortstop and safetycrash are going through The Horrors)
THAT REMINDS ME FOR WHATEVER REASON!! If Liz were to somehow exist in the timelines with the kids, how would she get on with them?
Depends on what timeline we're going for! And before clicking read more: As said I think having a kid is the worst thing that could happen to Blitzwing and Optimus and that does not change <3
In Safetycrash timeline she would have split because Megatron made good on his promised and killed Optimus' after Safetycrash's birth. Liz then decides to defect and free Isaac and Safetycrash while making the former promise to raise and protect his kid while Liz goes and faces Megatron. Liz loves Safetycrash but being the keeper of Optimus' memories from the spark merge also remembers the resentment, pain and worry they brought with. She wishes she could have done more but she follows Optimus' last wishes of Safetycrash being raised far away from all of this.
For Shortstop I haven't really thought of it. She probably formed after Shortstop was born as the mental load on the system worsened. Tries to raise Shortstop the best she can as an Autobot surrounded by Decepticons with the quirk Liz identifies more as a sire than a carrier. She's the most empathetic for Shortstop's struggles but doesn't have a lot of say in the system and struggles a lot with internal communication (they want her to not be there sooo bad). Shortstop has the least complicated feelings about her which isn't saying a lot but they understand Liz really tried to fill the space their sire left them.
I SHALL ALLOW ONE TREAT IF IT WAS A PERFECT WORLD so if "This was supposed to be a fling" Liz was a parent: She doesn't understand kids but she is trying her best and her calm energy and going along with whatever Crashstop does makes her really popular. She tires easily though and fronts infrequently compared to the others so she gets more "favorite aunt" status which is fine by her.
