I think Rock Lee would have a good chance. He's extremely physically fit and his taijutsu skills are amazing. He can move very fast and his strong willpower means he won't give up easily. Shikamaru might also survive. Despite not being as physically strong as some others, his intelligence is his weapon. He can strategize and outwit his opponents, finding ways to avoid direct confrontations and use the environment to his advantage in this Hunger Games - like situation.
Well, Kakashi could be a top contender. He's experienced, has a wide variety of jutsus at his disposal, and his Sharingan (even if it tires him out) gives him an advantage in combat. He's also very good at analyzing situations quickly. Hinata could also survive. Her Byakugan would allow her to see her opponents from a distance and her gentle fist style could be effective in close - quarters combat if she can get over her shyness and be more assertive in this life - or - death situation.
Naruto himself would be very likely to survive. His ability to quickly adapt, his large amount of chakra, and his powerful jutsus like the Rasengan would give him an edge. Also, his determination and his will to protect others would keep him going even in the toughest situations. Another one could be Sasuke. With his Sharingan, he can predict his opponents' moves and his skills with a sword and ninjutsu are top - notch.
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 Rock Lee could survive. His physical strength and speed, along with his determination, would serve him well. Also, Shikamaru. Despite not being as physically strong as some others, his high intelligence would enable him to outwit his opponents and avoid dangerous situations in the Hunger Games arena.
Artie could be a surprising survivor. Despite his wheelchair, he's very intelligent. In a Hunger Games crossover, he could use his brains to outsmart the other tributes. He might be able to set up traps or figure out the best hiding places. Also, the other characters might underestimate him because of his disability, which could work to his advantage.
Percy Jackson himself would be a likely survivor. His powers over water, his combat skills, and his ability to think on his feet would give him an edge. Annabeth Chase would also be a strong contender. Her intelligence and strategic thinking would help her navigate the challenges. Also, Katniss Everdeen from The Hunger Games. She is a skilled archer and survivor, so she could hold her own against the demigods and the other threats in the crossover arena.
Well, I think Ginny Weasley would be a strong survivor. She's feisty, brave, and a skilled witch. Her Bat - Bogey Hex could be used to great effect against opponents. Luna Lovegood could also make it. Her unique perspective and knowledge of magical creatures might give her an edge. For example, she might be able to befriend some strange magical creature in the arena and use it to her advantage. And of course, Harry Potter with his ability to face great evil and his quick thinking would be very likely to survive as well.
Naruto. He has incredible stamina, his shadow clone jutsu gives him an edge in terms of numbers, and he has the willpower to never give up. He could use his clones to scout the area, set up traps, and then when it comes to a fight, his rasengan would be a very powerful offensive move.
Elsa would be a strong contender. Her ice powers give her a huge advantage. She can defend herself easily and attack from a distance. Also, she has shown great self - control in difficult situations in her own story. But Anna also has a chance. Her determination and ability to make friends quickly could help her form strong alliances and survive.
In my opinion, Alejandro from Total Drama would be likely to survive. He's very intelligent and manipulative, which would help him form alliances with the Ice Age animals or other characters. He could also use his charm to get out of difficult situations.
The Shredder would be a likely villain. He could see the Hunger Games as an opportunity to finally get rid of the TMNT. He might manipulate the other tributes or even work with the Capitol to set up traps for the Turtles.
Naruto himself is often a popular choice. His never - give - up attitude and powerful jutsu make him a formidable character in the Hunger Games - like scenario. Sasuke is also popular as his cool and powerful demeanor can be interesting to see in the Games. Sakura, with her medical skills and growing combat abilities, can also be a fan - favorite in these fanfictions.
