Sorry, I haven't heard of the 'green text so long gay bowser cat story' before. It could be a very specific piece of fanfiction or a story created within a particular online community. If you can give me some more details, like where you heard about it or what kind of genre it might be (comedy, adventure, etc.), it would be easier to answer.
One possible theme could be acceptance. Given the 'gay' aspect in the title, it might explore acceptance of different sexual orientations within the context of the story involving Bowser and the cat. Another theme could be friendship or an unlikely alliance between characters that are very different, like a big - bad - like Bowser and a cat.
One difference is their appearance. Dark Bowser looks more menacing with a darker color palette. Also, Dark Bowser seems to have more powerful attacks compared to regular Bowser.
One key feature is his physical strength. He can easily overpower many of the characters in the Mario world. Another is his fire - breathing, which he uses as a weapon against his enemies. His spiked shell also makes him difficult to attack directly. And of course, his leadership over the Koopa Troopas is a notable feature.
Well, it's hard to say for sure. Bowser is a powerful character in his own right, with his fire - breathing and brute strength. But Dark Bowser is an even more menacing version, often having enhanced powers. It could really go either way depending on how the fight plays out in the game's story.
In some fanfics, there might be a plot where Bowser Jr. tries to prove himself to Bowser. He might take on a difficult task on his own, like stealing a precious jewel from a well - guarded castle. This shows his growth and determination to be a worthy heir to Bowser. And it also adds a touch of family - like relationship exploration between them.
One possible theme could be family. As Bowser and Bowser Jr. are father - son, the fanfic could explore the dynamics of their family relationship. It could show how they support each other, or how Bowser is trying to raise Bowser Jr. to be a worthy heir.
You can try fanfiction websites like Archive of Our Own or FanFiction.net. They have a wide variety of fan - created stories, including those about Bowser and Bowser Jr.
Some fanfictions might take a more comical turn. Picture Bowser and Bowser Jr trying to host a party in their castle but everything goes wrong. From the invitations getting lost to the food being ruined, it's a hilarious take on their characters.
Well, obviously Bowser and Dark Bowser are the main characters. Bowser is the well - known villain from the Mario series, and Dark Bowser is his darker, more menacing counterpart.
