Ricochet, Kalisto, Rey Mysterio, IO Shirai, Kacy Catanzaro.
Ricochet. I think Ricochet is the best one from the list. He is the strongest, and just as quick, or quicker like you said before. I would probably add in Rey, because of his experience in the ring, and fighting different opponents of different styles.
Deonna Purrazzo, Toni Storm, Tessa Blanchard, TJ Perkins, Britt Baker.
TJ Perkins. TJ Perkins knows a lot of holds, and has a lot of strikes, and he can take it to the air. He is well rounded, imo. He is really quick. He is resourceful, and creative, too.
Stone Cold Steve Austin, Paige, Dean Ambrose, Rhea Ripley, Pete Dunne
Pete Dunne. He seems to not only be a great striker, but is an expert at ripping a limb apart, especially the arms. He seems vicious. I don't know much about him, bit I prefer his style over Stone Cold. I'm not a big fan of Stone Cold as much as most people. On second thought, I seen some of his action movies; he know how to fight and take punishment. Stone Cold, too.
John Cena, Braun Strowman, Brock Lesnar, Nia Jax, Drew McIntyre
John Cena. Cena is pound for pound the strongest out of the list, and probably overall the strongest with his muscle control, and overall body strength. He would probably be a great leader, too. He is brave, and has the most experience. Bran Stowman, too. Braun could mow down them aliens with his size, power, and velocity.
Daniel Bryan, Becky Lynch, Samoa Joe, Chad Gable, and Kurt Angle
Daniel Bryan and Becky Lynch. Becky is an aquarius, so I'm assuming she is trustworthy, creative, honest, and original(Which are qualities you seem to have, too, since you're an aquarius). Also like you said, she seems to know a lot about how to survive. She is also a great wrestler, energetic, and determined. Daniel Bryan is one of the best wrestlers on the planet, and also knows how to strike, and he gives it his all.
Dakota Kai, Matt Riddle, Asuka, Sonya Deville, and Roman Reigns.
Roman Reigns. Roman was fighting cancer, and still is for pete sakes. He is a true hero. Even before I knew about that, I still would have picked him. He is strong, explosive, and has a lot of intensity. He is also a leader, and one of the hardest workers to have improved in the ring as much as he did, with each year.
AJ Styles, Charlotte Flair, Seth Rollins, Johnny Gargano, and Tommasso Ciampa
AJ Styles. AJ Styles plays video games, so I'm assuming he would know how to defend against aliens, lol. But seriously, one of the greatest of all time, in TNA and WWE.
