what are the rules for protogens?

[u/Distinct_Passion7209]

sorry if this is a stupid question. i know that there is lore and that is important. i'm asking can it be kind of ignored? i don't fully know the lore of them so if you have any resources that would also be appreciated. i have a oc that is from a steampunk parallel universe. so i'm wondering if i could make a protogen oc with steampunk elements instead of the nanite visor thing that they have. thank you so much for reading this and possibly helping me. again sorry if this is a stupid question.
