Hello! Another fantasy request from me!
So, I have an idea of a mermaid character. She is very serious and confident and works as a guard (cool beautiful trident comes in set). Also gets very offended when someone confuses her or her people for a sirens that drown humans. Mermaids are much less aggressive and consider sirens savages.
So, I thought how would bots or cons act with her. For example, they could meet her while searching for cybertronian relic that she is guarding. Maybe it has been in her city for a long time and became holy for her people. Or maybe it keeps some underwater beast caged. Anyway, she is not going to give up on it so easily. Though I’d like if at least some cons became her friends if that is possible (Breakdown or KO maybe?)
I 100% agree that the artifact hunt is going to be the best way to introduce this MC but.....
They are guarding an artifact, but my mind went instantly to it be a power source rather than a holy object. BUT!! You mention a trident and what if that's another artifact, but not the one the bots came here looking for.
During the artifact hunt portion of the show I, for one, thought there should be WAY MORE artifacts than I feel like where shown. Everything went by super fast for this story point (in my opinion). With how long it took Optimus and Soundwave to decode the coordinates and how large the data was (considering how long it took to download from the Nemesis) there should have been more artifacts.
So, lets say, there are more artifact to be found with varying abilities and power and not all of them are found at their coordinates. That being said, the bots have gone to coordinates and found nothing.
Now continuing with our MC. Their trident is 110% an artifact and the bots don't consider it because its not what they came for. I think they see the power the MC is able to wield with it, but if its not an "easy grab" the bots wouldn't take it.
I would say that Breakdown and KO would definitely be friends! I think during the time they are in captivity KO would be drawn by the beauty at first. The cocky attitude and prowess would have KO and Breakdown hang around. (Though I don't think it would go as far as to free them)
I feel like the MC would have a "Lone Wolf" attitude and continue to search for the power source that was stolen from their people, but not necessarily with the Autobots (who I think would rescue them). I think they would be pretty close to the Predicons actually.
I also wanna talk about the MC being above and below the water. Because I headcanon mermaids do have a "human" form in this world, but its not exactly perfect. Yes they have two legs and can breath oxygen, but there are patches of scales, lines where their gills would be (not open though) things like that. I only state this because if for the story to keep this MC in it, they have to have some sort of land mobility.
I am honestly loving this so much, I might be writing some short stories that go with this concept. Might be doing that right now.
I also have a headcanon on the abilities of the trident, I will be including that in one of the shorts.
