It could be Lincoln. He's shown to be resourceful in the Loud House. In the context of the Infinity War, he might be able to adapt quickly and find ways to use the power of the Infinity Stones against Thanos if he got his hands on them.
Luna might be a strong contender. Her passion for music could translate into some sort of sonic power in the crossover. She could use her music to disrupt Thanos' plans or even control some of his minions. Her wild and creative personality would give her an edge in coming up with unique strategies against the powerful villains.
I think Groot from Guardians of the Galaxy is already quite an unexpected character in the Infinity War story. But if we want to be even more out - there, how about Snoopy from the Peanuts? Imagine Snoopy flying his doghouse into the middle of the battle against Thanos and using his imagination - powered antics to distract the villains. It would be a really wacky and unexpected addition.
I think Lincoln Loud would be really interesting. He's used to dealing with a big family and all kinds of situations at home. In the Spyro world, he could use his problem - solving skills to help Spyro on his quests. His curiosity would also make him eager to explore the new world of Spyro.
One possible plot could be that the Infinity Stones are hidden in Royal Woods. Thanos sends his forces to find them. The Loud family discovers what's going on and decides to protect their town and the world. Each member of the family could be assigned to protect a different area, and they'd have to use their individual quirks and abilities to fend off the invaders. They might also team up with some of the Avengers who come to Royal Woods for help.
I think Lincoln and Spongebob would be an interesting pairing. Lincoln is used to living in a big, chaotic family and Spongebob is always full of energy and optimism. They could get into all sorts of misadventures together, like exploring a new part of Bikini Bottom or trying to solve a mystery in Royal Woods.
I think Lincoln and Spongebob would be an interesting pair. Lincoln is always getting into various situations in his large family, and Spongebob is constantly having adventures in Bikini Bottom. They both have a sense of curiosity and a love for exploration. They could learn a lot from each other, like Lincoln could show Spongebob about life on land and Spongebob could introduce Lincoln to the wonders of the ocean.
It could be Makarov. His experience and extremely powerful magic could give him an edge. He has seen many battles and his Fairy Law is a very strong spell. In a situation like an Infinity War, his leadership and power would be crucial for the Fairy Tail guild.
The Red Ranger would likely be a top contender for the most powerful. They usually have strong leadership skills and often the most powerful attacks among the team. However, if we consider villains, Rita Repulsa could be very powerful in an Infinity War scenario. With her magic and cunning, she could cause a lot of trouble for the Rangers.
Leni and a bad - luck character who is always in a hurry to fix things but just makes them worse. Leni's somewhat oblivious but kind - hearted nature could either be a hindrance or a help. They could get into all sorts of misadventures together, like trying to fix a fashion disaster that the bad luck caused, but instead creating an even bigger mess.
I think Lincoln would be the most likely. He's the main character among the Loud kids and often takes on leadership roles in his own family situations. He's also curious and adaptable, which are good traits for a Power Ranger. He would be eager to learn about the Ranger powers and use them to protect both his family and the new world he's a part of.
I think Lincoln would be really interesting. He's used to dealing with a big family in The Loud House, so in Sword Art Online, he could use his leadership skills to form a guild with the other characters. His ability to adapt to different situations at home would come in handy in the dangerous world of SAO.
