How would an OC interact with the RWBY characters in a transported to world RWBY harem fanfiction?

Well, it could be really exciting. The OC might find themselves in the middle of all the action and drama in the RWBY world. They could form unique relationships with the different characters. Maybe they'd team up with Ruby and her friends against the Grimm. And in the harem aspect, they could have some interesting romantic or friendly interactions with multiple characters, like Weiss, Blake, and Yang.

Ruby would likely try to find a way to end the war quickly. She has a strong sense of justice and wouldn't stand for all the death and destruction. Weiss might use her knowledge of politics and strategy to try and influence the leaders in the fanfiction. Blake would probably be more on the sidelines, observing and trying to understand the different sides of the conflict. Yang would be right in the middle of the action, trying to protect the innocent and fight against the unjust forces.

The gamer could interact with Ruby by showing her the unique weapons that can be created with UBW. Ruby, being a weapon enthusiast, would be extremely interested. They might also team up during battles, with the gamer using UBW to support Ruby's scythe - based combat style.

Ruby would be the most likely to engage with SCP fanfiction concepts in a positive way. She has an open mind and a sense of adventure. So she might see the SCPs as new challenges to face. Weiss would be completely against it. She values elegance and propriety in literature and SCP fanfiction doesn't fit that bill. Blake would look at the SCP concepts from a psychological angle. She'd wonder what makes people create such dark and complex entities. Yang would be all about the action. If there are strong SCPs in the fanfiction, she'd want to show them who's boss.

Weiss, with her more refined upbringing, could initially be a bit shocked by the differences in the Yamato's world but would soon start to find ways to use her skills. She might help with strategic planning, using her knowledge from Beacon Academy.

Hinata could befriend Ruby. Ruby is the leader of Team RWBY and Hinata is a key member of Team 8. They both have a sense of loyalty and a strong will to protect. Hinata could show Ruby some of her gentle fist techniques, and Ruby could introduce Hinata to Crescent Rose and how it works. Their friendship could be based on mutual respect for each other's combat abilities.

Gilgamesh would likely interact with Ruby in a rather condescending way at first. Since he's used to being the most powerful, he might underestimate her silver - eyed powers. With Weiss, he'd probably be intrigued by her family's status and her own ice - based powers, maybe trying to manipulate her into serving him.

Ruby would likely be curious and excited. She'd probably see the Chaos Emeralds as a new source of power to help her in her battles. Weiss would be more cautious, perhaps seeing them as a potential threat to the order she values. Blake might be intrigued yet hesitant, remembering how power can be misused. Yang would be eager to test out their strength. For example, Ruby might try to incorporate the energy of the emeralds into her scythe attacks, while Weiss would be researching how to contain their power if it got out of hand.

Ruby would probably be very excited to meet Geralt. She might ask him a million questions about his adventures and his weapons. Geralt, on the other hand, would be more reserved but would respect Ruby's enthusiasm. Blake might be a bit cautious around the Witcher at first, but would soon be interested in his knowledge of different creatures. Yang would be eager to spar with Geralt to test her strength. And Weiss would be curious about the Witcher's magic and how it compares to her own Glyphs.

The characters would likely have an initial period of confusion. The Warframe Tenno, being used to their own high - tech battles, might be startled by the more 'primitive' but still effective weapons of RWBY. Meanwhile, the RWBY characters could be in awe of the Warframes' advanced abilities. For example, when a Warframe uses teleportation, the RWBY team would be both amazed and a bit suspicious. Eventually, they would start to work together, with the Warframes teaching the RWBY characters about advanced combat tactics and the RWBY characters showing the Warframes the ins and outs of their world.
