do you think that its possible to for one bot to forcibly spark bond to another? like where they force the spark chamber open and they force the bond? or does it have to be a mutual thing? and can the spark bond be broken through another way other than one bot dying? like my idea is that they can be broken, bot only after a lot of time and physical and mental distance where one isn't responding to the bond? there's no clear answers and wanted to know your hcs.
Overall, it depends on the bond (for both questions).
There are two main categories that bond types fall into: Chosen (bonds that are the result of two or more already-created mecha bonding with one another) or Creation (bonds between two or more mecha that are present within the mech at the time of creation). Some bond types can fall under both categories, usually due to any manner of cold-construction related fuckery.
I suppose you could compare chosen bonds and creation bonds to romantic/patonic and familial relationships respectively, but I find that reductive and not entirely accurate.
As for the bond types themselves;
Conjunx/Amica bonds (chosen bonds between two mecha) can be forced, but with the way sparkbonds are formed, it would take a lot of time. Chosen sparkbonds take multiple, frequent instances of merging over about a vorn to permanently form--and even longer still, if one party is unwilling. It's still possible though--sparkbonds are as much about feelings as they are about spark biology; spend enough time with your spark shoved against another's, and something's going to happen.
(Fun fact: There is no physical nor physiological difference between a conjunx and amica bond, only cultural differences. Both require the same method of creation, and both have the same effects on the bondeds.)
Trinebonds (chosen bond between three mecha, with all members bonded to the others) are much the same, though with a few differences. It generally takes longer for a full trine bond to form than a binary bond, since there are three sparks involved instead of two.
(Fun fact 2: 'Trines' are not seeker-exclusive, nor even flight-frame exclusive! The formation of a three-way bond has nothing to do with frame type. Three-way bonds weren't very common, nor did they have a common name, before Nova Prime and the creation of cold-construct seekers. With the original seekers, they were pre-bonded to each other in groups of three, due to a prevailing theory that mecha bonded to each other would function better during battle, being able to more effectively account for the actions of the other 'trine' members [this same logic was applied to created gestalts, up to its logical extreme]. The association between seekers and bonded trines stuck, even after they were released from Nova's jurisdiction. Thus, trines are: 1. seen as a flier or seeker-specific bond type, and it's generally disrespectful to refer to non-flier three-way sparkbonds as trines for history's sake, and 2. trinebonds are culturally regarded as more gestalt-like than as conjunx or amica, which only adds to culture-shock-related confusion between [non-gestalt] grounders and seekers.)
Guardian bonds (chosen bond between an adult mech and their charge, typically a youngling) can technically be forced since they're also chosen bonds, but that's practically impossible due to the mechanics of forming the bond. Unlike the first three bonds, guardian bonds do not form via spark merging, instead by vorns (as in 10+ vorns) of near-daily close contact (youngling plating very thin, allowing more spark radiation through to those around them and more easily facilitating guardian bonds to form; this is also why youngling em-fields are so disregulated), and are far more reliant on emotional reciprocity than other chosen bonds. Guardian bonds are the natural result of grown mecha taking care of newsparks and younglings from hotspots and/or other (non-carrying) sources. To 'force' one, the only way I'd think would be for an adult mech to manipulate a youngling into considering them their guardian, but that isn't quite forcing in the way you mentioned it.
After those four, that leaves only the creation bonds, which are impossible to force in the typical sense (as in, one member of the bond forcing another. For some, it is possible to 'manufacture' creation bonds, though I don't suppose that is what you meant by force either.)
Gestalt bonds (A creation bond between two or more mecha that facilitates a combined form) were practically unheard of before (and say it with me now folks) Nova Prime and his cold-construction program. Gestalts were created after the pre-bonding of seekers was proven successful, and Nova's scientists devised of a manufactured squadren of mecha who were not only connected via sparkbonds, but literally connected in their ability to combine into a greater consciousness and form. Shockingly, this did not immediately brick the processors of all gestalt members, but the bandwith needed to process one's self, the selves of 5+ other individuals, and a giant frame you didn't have five kliks earlier was, naturally, more significant than that provided by the natural (or, more realistically, the cheapest Nova could afford) Cybertronian form. This results in the trend of combiner forms having sub-par mental faculties and/or severe personality quirks, but since they were good at blowing things up, Nova and his scientists didn't care. After a mech's creation, gestalt bonds cannot be formed; they require physical frame constraints that cannot be modded into a frame post-creation.
Carrier/sire bonds (creation bond between a carried sparking and their progenitors) is a naturally-occurring bond that forms when a sparkling, created via a spark-merge between two or more mecha, emerges. The sparkling's spark is automatically connected to their carrier's and sire(s), though if the sparkling is removed from one or more of their progenitors' at a great enough distance for a long enough time, this bond can dissolve on its own (more on that later). Carrier bonds are also formed by specifically cassette-carrier frames when they create sparklings on their own.
(Fun fact 3: Cassette carriers are the only Cybertronian frametype capable of true asexual reproduction [besides planetformers and titans, but they aren't technically 'Cybertronian'], and they are what carrying is named after!)
Twin bonds (creation bond between the resulting two mecha of a split-spark creation) are strange, since they aren't technically bonds at all; they're the physiological result of single spark splitting as it's created by the Allspark. A split-spark cannot be formed after creation (attempts to do so only result in a dead mech with a broken spark chamber), and all attempts to split frozen sparks to manufacture twins has also failed. No mech has ever been known to carry a true split-spark (though carriers, especially cassette-carriers, can carry multiple sparks at once, resulting in technical twins, but not split-spark twins). Split-spark twins each have their own frames, but share a spark between them, about half a spark to each mech. They are almost always smaller than the average of their frametype, barring frame mods, and are know to behave irratically when seperated from their other half. Common superstition reviles them as 'less-than' normally forged mecha, similarly to the cold-constructs of later times.
As for breaking bonds, chosen bonds can broken a few ways; death (the shock of which most likely resulting in reciprocal death of the other bonded(s), especially in well-established and healthy bonds), dissolution (a long period of sparse contact and intentional self-isolation; it's generally the least painful method overall, but it takes a while), and surgical bond severing (quick and non-lethal, but extremely painful and hard to perform; due to its controversial nature, few spark surgeons are trained in the practice). When wishing to be rid of an unwanted chosen bond, most pick dissolution.
Creation bonds are trickier; Twin 'bonds' cannot be removed--to do so would kill both mecha immediately. Gestalt bonds also cannot be removed without killing the mech getting the bond removal, though remaining gestalt members may survive being down a member, Primus willing. Carrier/sire bonds can be removed like chosen bonds as normal, though. Trine bonds made before creation can also be removed like regular chosen bonds.
Anyway, have some baby Sunny and Sides.
When they were really young, Sunstreaker was actually pretty small compared to Sideswipe (their spark split was more of a 40/60 than 50/50), but Sunny got heel lifts as soon as he was old enough, so now they're around the same height.
