Redemption is a common theme. The OC often serves as a catalyst for Vader's possible redemption, seeing the good in him even without his suit. For example, in many stories, the OC might encourage Vader to turn away from the dark side.
There's also 'A New Hope for Vader (Suitless)'. In this fanfiction, the OC is a healer from a far - off planet. When she encounters suitless Vader, she tries to heal not just his physical wounds but also his broken spirit.

One possible plot could be that Vader, without his suit, is found by Obi - Wan in a hidden location. Obi - Wan, despite their past, decides to help Vader recover.

Their relationship might start with suspicion. Obi - Wan would be cautious as he's seen Vader's evil deeds. But as Vader is suitless and perhaps more 'human' in a sense, Obi - Wan could start to see the Anakin he once knew. This could lead to a slow rebuilding of trust.
