To develop Cooler further, he could be given a redemption arc. Maybe he starts off as a villain but gradually realizes the error of his ways. He could befriend some of the younger Z - fighters who look up to him despite his past. This would force him to be a better role model and in the process, he would change and become a more complex and interesting character.
With his friends in Konoha, Naruto could be seen as both an asset and a potential danger. His friends might be in awe of his new abilities but also worried about how his connection to Cooler could draw unwanted attention to the village. His relationship with Kakashi could also change as Kakashi tries to help Naruto understand and control his new powers.
Durability is a key factor. Yeti coolers are made to be tough, able to handle being knocked around in the back of a truck or on a boat. This makes them ideal for the rugged outdoors.
Power is a common theme. Since both Frieza and Cooler are powerful characters, many fan fictions explore how they gain more power, or how they compare their power levels. Another theme is family. Their relationship as brothers often plays a big part, like in stories about their rivalry or their attempts to cooperate. Redemption can also be a theme, especially for Cooler in some fictions where he tries to make up for his past actions.
Well, one possibility could be that Naruto inherits some of Cooler's unique abilities. Maybe he has an innate power of extreme cold that he has to learn to control. This could lead to new jutsu development as he combines his existing ninja skills with this new power.
One great 'Dragon Ball Z Cooler' fanfiction is 'Cooler's Redemption'. It explores a scenario where Cooler decides to change his ways and ally with the Z - fighters. The story has well - written battles and character development.
I'm not sure specifically what this 'cooler trains with west kai' fanfic is about as there isn't enough information given. It could potentially be about trains that are cooler in some way, perhaps technologically advanced or having unique features, and a character named West Kai might be involved in the story related to these trains.
The title 'cooler trains with west kai' fanfic gives no clue about the author. It could be someone new to fanfiction writing or a more experienced writer who is exploring a new idea. Maybe it was written by a group of friends as a collaborative project, but again, with just this title, there's no way to know for sure.
