Blake. She's very agile and stealthy. These traits would allow her to avoid the Xenomorph's attacks and potentially find a way to outwit it. Plus, she has experience in dealing with dangerous foes, which would come in handy in this situation.
Ruby. She's extremely fast and has shown great combat skills. Her ability to quickly move in and out of danger would give her an edge against a Xenomorph. Also, she has a strong sense of determination which would help her stay focused during such a terrifying encounter.
Zero and Ruby would be a likely pairing. Zero is a powerful and skilled fighter, and Ruby has a lot of potential and a unique weapon. They could learn from each other's combat styles. Ruby could learn about Zero's more serious and battle - hardened approach, while Zero could be inspired by Ruby's enthusiasm and creativity in fighting.
I think Ruby and a young, adventurous Pilot would make a great pairing. Ruby's enthusiasm and eagerness to learn new things would mesh well with a Pilot's daredevil nature. They could exchange stories about their respective worlds while fighting side by side.
Ruby would be a likely candidate. She's already known for her speed and agility in combat. If she were to be affected by the Speed Force, it would enhance her existing abilities to a whole new level. She could move so fast that she becomes almost invisible to her enemies, and her scythe attacks would be even more deadly with the added momentum.
Ruby. She's impulsive and has a love for food, especially cookies. It's easy to imagine her getting excited about a food fight and accidentally starting one by playfully throwing a cookie at Weiss or someone else, which then escalates into a full - on food fight.
Ruby would be a likely candidate. She is the leader of the RWBY team in their own universe, and she has a natural ability to inspire others. Her quick thinking and combat skills would also be valuable in the Battlefield 1 setting. She could quickly assess the situation on the battlefield and make decisions on where to move the team and what objectives to pursue.
Ruby could be a likely candidate. She has that natural leadership quality and a strong drive to protect others. Her silver - eyed power already shows she has some latent and unique abilities. Combining that with the super saiyan form could make her an even more formidable fighter. Also, she's the main character, so it would be a great plot twist to see her achieve this form first.
Kirby and Yang could also make an interesting pairing. Yang is strong and brash, while Kirby is small but mighty. Their personalities contrast but could also complement each other well. Yang could provide the brute force while Kirby could use his unique powers to support her in battles, like when she's facing a particularly tough Grimm.
Will might also have a chance. He is charming and persuasive, which could help him form alliances. He also has a strategic mind from his work in the law firm, and he could use that to outwit his opponents in the Hunger Games.
I think Lynn could also survive. She's tough and athletic. If it came down to it, she could probably outrun the animatronics or even fight them off physically. She's not one to back down from a challenge, and in a FNAF - like scenario, her physical abilities would be very useful. However, she might need to learn to be more strategic as the animatronics are not your typical opponents.
Nora could also be a likely candidate. She's very energetic and not one to be intimidated easily. When she sees Goku's amazing power, she would probably be excited and want to team up with him right away. She would be constantly asking Goku about his world and his powers, and they would bond over their love for combat and having a good time.
