Loki in a cartoon Infinity War fanfiction could be a fascinating focus. He's so full of mischief and trickery. You could show his internal struggle between his desire for power and his loyalty (or lack thereof) to his brother Thor in a more cartoony, over - the - top way. Maybe he teams up with the heroes against Thanos in the most unexpected way, all while plotting his own schemes on the side.
Batman would be a great character to focus on. He doesn't have superpowers like the others but his intelligence and strategic mind are his greatest assets. In a 'Justice League Infinity War' fanfic, he would be the one trying to figure out the complex nature of the Infinity Stones, coming up with plans to outwit Thanos. He might also have some tense moments where he has to rely on the super - powered members of the League in ways he's not used to, which could lead to some great character growth and interesting interactions.
Nebula is an interesting choice as well. She has a complex relationship with Thanos and has been through a lot. In the aftermath, she could be a key figure in trying to find a way to undo what Thanos has done. Also, her unique skills and knowledge of different parts of the universe could play an important role in the fanfic.
I think Naruto would be really interesting. He has this never - give - up attitude and his powerful jutsu. In the Gears of War universe, he'd be like a wild card, using his speed and Rasengan against the huge and tough enemies there.
Arya Stark would be a great choice. You could write about her using her assassin skills to target key military leaders during the war. For example, she could infiltrate enemy camps disguised as someone else and take out important commanders, which would have a huge impact on the battles.
Well, it would be much more light - hearted in many ways. The Cartoon Network characters have a different style of humor and action compared to the serious and often dark tone of the original Infinity War. For instance, the Powerpuff Girls would bring a sense of girl - power and sassy dialogue, which is quite different from the brooding heroes in Marvel's Infinity War.
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.
I think Riku and Captain America would be a great pair. Riku has a strong sense of justice and has fought his own inner demons. Captain America is all about truth, justice, and the American way. They could bond over their shared values. Riku could show Captain America some of his cool Keyblade moves, and Captain America could teach Riku about strategy and leadership in battle.
Mercury from RWBY could be an interesting character to focus on. He has a rather morally ambiguous nature already. In a Darkwatch fanfiction, he could be tempted by the power of the Darkwatch's enemies, like the vampires or demons. His prosthetic legs could also be given some kind of dark upgrade, and we could see him struggle between his own self - interest and the greater good in this new and dangerous setting.
Raphael could be really interesting. In the 2003 version, he is hot - tempered and tough. In the 2012 version, he also has a strong personality. Seeing how he reacts to his counterpart and how they might either clash or bond could be a great focus. Maybe they have a friendly rivalry as they compare their fighting skills.
