He might fit in as an unexpected ally at first. Pretending to help the RWBY team against a common enemy, but then reveal his true intentions later. For example, he could offer to help fight a powerful Grimm, but in reality, he wants to steal some valuable resource from Remnant. In the RWBY universe, his flying abilities and weaponry would be quite unique compared to the usual weapons and powers of the RWBY characters.

Well, in some fanfictions, Starscream from Transformers Armada might find himself in the RWBY world. He could be intrigued by the Dust, which is a unique power source in RWBY. He might try to steal it or use it to upgrade himself. The RWBY characters, on the other hand, would see him as a strange and powerful new enemy. They would have to figure out his weaknesses, which are different from the Grimm they usually face. And the Armada's presence could mean a whole new level of threat to the RWBY world, as they are used to dealing with smaller - scale threats compared to the massive forces in Transformers.
He could be integrated as a powerful enemy at first. He might target the academies because he sees them as places that are trying to control and limit power, which goes against his own philosophy.

Well, it would be very strange considering Starscream is male. But if such a fanfiction were to exist, it might involve some sort of alien or magical transformation that enables him to carry a spark or something equivalent to a pregnancy.

I'm not sure if there is a specific fanfiction directly combining Transformers, Starscream, and RWBY. However, you could try searching on popular fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. Maybe there are some creative writers out there who have mashed up these different universes in an interesting way.
A Dragonborn OC can fit into the RWBY universe by having their own unique backstory related to dragons. For example, they could have been born in a world where dragons were both feared and revered.

They could become a new type of huntsman or huntress, using their powers for good.
A fanfiction could have Starscream arriving in the RWBY universe. Maybe he could be mistaken for some kind of new Grimm at first. His mechanical nature would be a huge contrast to the organic and magic - based world of RWBY. He might try to take over or find a way to use the Dust in RWBY for his own purposes, seeing it as a valuable resource similar to Energon in his own world.
Pyrrha could be reincarnated in the MTG universe. Angel, who has some knowledge of the cycle of life and death in the MTG multiverse, discovers her reincarnated form.

As she grows in power, they form a bond and start to explore the MTG universe together, facing various threats and making new allies.
Harry Potter himself could be seen as a kind of foreign wizard in the RWBY world. He might be initially confused by the concept of Dust but quickly adapt and use his magic to enhance the RWBY team's capabilities. Hermione would probably be fascinated by the study of Dust and Semblances, and use her vast knowledge to help bridge the gap between the two magic systems. Ron could be the one who forms quick friendships with the RWBY characters, sharing his sense of humor and loyalty.
In a 'noctis in rwby fanfiction', Noctis' ability to use magic, like his elemental attacks, would be a significant factor. In the RWBY world, magic is a somewhat mysterious and not - fully - explored aspect. Noctis could introduce new forms of elemental combat. His fire - based attacks could be used to counter ice - type Grimm, and his lightning attacks could stun enemies, allowing his RWBY allies to deliver finishing blows. Also, his ability to enhance his physical abilities with magic, such as increased strength or speed, would make him a formidable ally in battles against the powerful Grimm and any human adversaries that might arise.
Well, Bruce Wayne could bring his detective skills. He's like a super detective in his own world. In RWBY, he could help uncover secrets about the Grimm or the various factions. Maybe he'd team up with Team RWBY and use his martial arts skills in combat against the bad guys.
