Ok sooo... I know your bug planet has no contact with the rest of the universe but just for funsies - what if Shit Happens TM and MiniMint gets yeeten there? Idk teleport malfunction or sth. She's human-sized so she wouldn't stand out much. She would be pretty scared tho, not so much about herself but about her family freaking out (all of them have some degree of separation anxiety lol).
She always does her best to be independent. On Earth it was fine but being so young and tiny while on Cybertron frustrates her easily, even if by human standards she's an adult and has a degree in rocket science engineering. Luckily her adoptive family is very supportive. Other than that she's nice, friendly, nerdy and helpful.
Now what would Kabula do with such find?
I'm going to ignore the canon way anyone from Thalamhan would treat a cybertronian, since it would be too massive of a deal for anything casual, so instead I'll set it aside and just go off of the character without any of the cultural sentiment involved XD (if youd like that version then the shortened answer is that: cybertronian from another planet = Thalamhan is not alone = Gealach was right = everyone parties and/or goes crazy = instant celebrity status)
So the funny thing is, human-sized on Thalamhan is the same thing as human-sized on Cybertron; the only way Thalamites become human sized themselves is when they're off world and have to mass displace. Because of this, Mini would definitely stand out if she was noticed, and being so small, she would meet Kabula somewhere between her shin and knee XD In terms of interaction, I think Kabula would first not exchange pleasantries but have more of a discussion about how Mini will navigate the city at her size, all official business. If they were to actually have a proper conversation though, then Kabula would probably like her. Mini would remind her of Tympani, definitely, and she'd believe she'd have a better chance at sharing common interests with her instead. After all, Tympani doesn't tend to talk about her own nerdy interests with Kabula, since she knows she's not that kind of person. Too busy caring about the law for that! (Her girlfriend, on the other hand...)
