Obviously, Garfield himself would be the main character. Jon Arbuckle, his owner, would also likely be in it. Odie, the lovable but not - so - smart dog, would probably be there too. There could also be some new characters like a time - traveling wizard who helps Garfield understand his new powers, or an antagonist from another time period who wants to steal Garfield's time - controlling abilities.
Garfield, of course. Alongside him, we'd expect to see Jon and Odie. But it could also introduce some time - specific characters. For example, during his travels to the Middle Ages, he might meet a knight who challenges him to a duel. Or in the future, he could encounter a robotic version of himself that was created by an evil corporation trying to take over the world through time manipulation. There could also be a time - guardian character whose job is to keep the time continuum in order and who has to deal with Garfield's meddling.
Garfield is a must - have character. Then there's Jon, who might be really confused when Garfield starts disappearing and reappearing at different times. Odie could play a role in either helping or hindering Garfield's time - traveling adventures. There could also be characters from different historical eras. For instance, a pharaoh in ancient Egypt who mistakes Garfield for a god due to his time - bending abilities. And maybe a mad scientist from the future who is jealous of Garfield's power over time.
One possible plot could be that Garfield becomes the master of time to stop an evil force from changing the past in a way that would eliminate lasagna from existence. He travels through different time periods, from ancient Egypt where he tries to find the origin of a key ingredient in lasagna, to the future to see if there are any threats to his favorite food. Along the way, he has to deal with time paradoxes and his own laziness getting in the way of saving the day.
There could be a new trainer who has a very different style of training Pokémon compared to Ash. Maybe a young girl who uses music to communicate with her Pokémon. Another potential character could be an old Pokémon sage who has a vast knowledge of ancient Pokémon lore and can offer Ash some valuable advice on his journey.
Obviously, Percy Jackson himself. Then there could be Annabeth, his girlfriend, who could support him in his new adventures as the master of water. Grover might also be there, providing some comic relief and also helping out with his nature - related skills when it comes to water - based environments like swamps.
Obviously, Kankuro could be a main character as he is a well - known puppet master in Naruto. For the harem members, it could include some of the female ninjas like Temari, who has a strong personality. Another could be Sakura, as she is a main female character in the original series and could be part of an interesting dynamic with the puppet master.
Garfield is the central figure in 'Garfield and Friends 20 Garfield Stories'. He is a cat with a big appetite for lasagna and a penchant for sleeping. Odie, the somewhat clueless dog, is also a main character. And we can't forget Jon, who takes care of Garfield and often finds himself in comical situations because of Garfield's antics.
One potential character could be Sasuke. He has always been highly skilled with weapons and his Sharingan would give him an edge in mastering knife techniques. He has the determination and the combat skills to be a great knife master in a fanfiction setting.
It could be very negative. The Garfield brand is known for its humor and family - friendly appeal. Linking it with Hitler through fan fiction would likely make people associate the brand with something inappropriate and offensive, which might turn away many fans, especially parents who don't want their children exposed to such inappropriate and disturbing combinations.
There could be a wise old wizard who has knowledge about the true nature of the Master of Death and becomes Harry's mentor. Maybe a powerful magical creature that is drawn to Harry's power and offers its assistance.
There could be some new characters introduced. For example, an old hermit who has a deep knowledge of ancient trap - making techniques and teaches Naruto some of his secrets. Also, some of the villains from the original Naruto series might appear, like Orochimaru, who would be intrigued by Naruto's newfound skills and try to either steal them or find a way to counter them.
Lara Croft could be one. She's a strong and independent adventurer. Her skills in exploration and combat would make her an interesting addition. She could team up with Master Chief and there could be a mutual respect that might lead to more than just friendship.
