Omg hii I saw that you wanted some headcanon ideas and I don't see many Cybertronian reader ones, so, how do you think the tfp transformers (specifically soundwave and shockwave but you can add however many you want!) would show their affection? (Btw I love that you write for gender neutral reader!)
Cybertronian reader x tfp Schockwave & Soundwave
How would they show their affection?
Firstly, if you become his friend/partner, Soundwave will be incredibly devoted to you. Soundwave does not seek empty connections, and if you were able to gain his affection, know that you can always count on him
Soundwave will be protective of you. He won't make a scene, but if someone on the Nemesis speaks to you in an inappropriate tone, he will appear behind your back as a threatening, silent shadow. Everyone knows it's best not to mess with their mysterious communications officer, and if you are in his company, you will likely be avoided as well
More doors will be open for you than for others, because you have Soundwave's loyalty, and Soundwave has Megatron's loyalty, which automatically means you have it too. It will be easier for you to get some information or in general get something, since Soundwave has access to almost everything on the Nemesis
Soundwave always keeps Laserbeak with him, but only you would be allowed to actively interact with his bird. Laserbeak, getting used to your constant presence near Soundwave, would also start trusting you, reacting calmly to your touches and perhaps even sometimes sitting on your shoulder (I headcanon Laserbeak as Soundwave's pet; I'm not sure what he actually is, but I like to think that Laserbeak is something like Soundwave's tame bird)
Shockwave is driven by logic, so it is more likely that you gained his affection because you proved your intelligence, rationality, and showed the ability to be an interesting conversationalist and a useful, effective colleague
Shockwave would have long conversations and discussions with you. He doesn't often meet those who understand him and with whom he finds it interesting to talk, and communicating with you is always like an interesting puzzle for his processor. He is always interested in hearing your opinion on something
Aside from Megatron, to whom he must report, you will always be the first to know about the results of his experiments, because he knows you will appreciate it and possibly give some adjustments. He respects a sharp mind and ingenuity
You will be a frequent and always welcome guest in his laboratory. He prefers to work alone, as others are perceived as unnecessary noise, but you are the exception. You complement the space and increase the efficiency of his work, as he allows you to be his partner in his experiments and use his equipment. Eventually, you will no longer be a guest, but a part of the laboratory
I hope you liked the result, and thanks for the request <3! I'll probably make two more parts on this topic, with all the other Decepticons and Autobots
