MCU-based roleplays: Canon x OC desires inside!

[Messianic Manic]

Hello, everyone! Thank you so much for clicking on my humble little searching thread.
First and foremost, I hope you're having a great day! I'm Messianic Manic and I'm so happy to be here with you all!
My ons/offs thread is linked in my signature for your reference. Also: where we RP (chat, PM, email, thread, etc.) are up to YOU. I am not picky at all. It's all up to my partners where we do things.

About me as a collaborative writer.
The most important detail is that, at this time, I am looking to play my OCs against canon characters. This is my main interest at this time. I know this can be a bit off-putting and opinions of this type of roleplaying vary. But this is simply what I like to do!

Onto the ideas!
I am also willing to hear any ideas you have, or any twists to listed ideas you might have! My main goal is always to have an RP that my partner and I enjoy equally.

• Polyamorous: Steve Rogers, Bucky Barnes, and my female OC. It seems to go without saying that Steve and Bucky would share everything. Why wouldn't they share a woman if they both fell for her? I have a plethora of ideas for how this can go as well, it's probably best to inquire about ideas if you're interested instead of me listing them all here.
• Unknown Soldat: Bucky Barnes and my female OC. Bucky's girlfriend, before the war, before HYDRA. Long before his brain was ever scrambled a small Asian girl had his heart. However, when he went off to England, he did not get a single letter from her. Her family was interned and she was experimented on alongside her brothers. 70 years later, a kill squad that specializes in taking down rogue HYDRA assets comes for Bucky. When the mask comes off of the sole female of the group, he finds it's the love of his life trying to end him.
• Buck In Time. A little similar to the Unknown Soldat idea. Much like Steve going back to be with Peggy, Bucky wanted a chance to go back and be with the woman he lost. So many issues with this idea, such as him being legally dead, his abnormal arm, and trying to find ways to explain everything to his beloved. Or perhaps, she had already moved on?

I am very bad at BBCode. But I've tried to make this pretty and readable.
