Definitely not. Mario and Sonic are well - known characters mainly targeted at younger audiences. Pregnant fanfics about them are inappropriate because they distort the innocent nature of these characters. The games they come from are about adventure, competition, and fun, not such mature themes.
Obviously, Sonic himself is extremely popular. He's the main character, after all. Tails also often makes an appearance as Sonic's sidekick. Knuckles is another popular one, with his strength and connection to the Chaos Emeralds. And then there are the villains like Dr. Eggman who are frequently part of the death battle scenarios in these fanfictions.
Well, one interesting plot could be Sonic facing off against an unexpected and powerful new foe. Maybe a character from another universe who has unique powers that Sonic has to figure out how to counter during the death battle. Another could be Sonic teaming up with an unlikely ally in the fanfiction's death battle scenario.
In the 'naruto vs ichigo death battle reaction fanfiction', reactions can be quite diverse. For Naruto fans, they might cheer when he uses his Rasengan in a creative way against Ichigo. Ichigo fans, on the other hand, would likely react strongly when he unsheathes his Zanpakuto and shows off its special abilities. There could also be a sense of disappointment from fans if their favorite character is losing or not performing as expected.
One idea could be a racing tournament where Mario and Sonic team up against some new, powerful villains. They have to combine their unique skills, like Mario's jumping and Sonic's speed, to overcome the challenges of the track which is filled with traps from both of their worlds.
One common theme could be the two characters overcoming differences. Since Sonic is all about speed and Mario is more about platform - jumping and rescuing princesses, they might have to bridge those gaps in the fanfic.
First, decide on the basic plot. Are they going to be friends, rivals, or something else? For example, you could start with them meeting for the first time. Then, think about the setting. Will it be mostly in the Mushroom Kingdom, Sonic's world, or a new place? Next, create some conflict. Maybe a new villain emerges who wants to take over both of their worlds. After that, start writing the opening scene, like 'Mario was on his way to rescue Princess Peach when he noticed a strange blue blur in the distance...'.
In 'Dark Sonic vs Shadow' fanfiction, it often showcases intense battles. Dark Sonic represents Sonic's darker, more aggressive side. Shadow, with his own set of powers and a complex personality, makes for an interesting adversary. These fanfictions usually explore different power levels and the clash of their ideologies. For example, Dark Sonic might be driven by raw power and a sense of chaos, while Shadow is more focused on his own goals and past traumas. The battles can be written in a very dynamic way, with vivid descriptions of their super - speed movements and energy blasts.
The fan fiction often plays with the idea of alternate universes. Sonic coming from his normal, bright and colorful world, and Sonic.exe from a much darker, twisted realm. The interactions between these two different versions of Sonic in the cross - over scenarios are full of potential. Writers can explore how Sonic's values and abilities are challenged when faced with his doppelganger from a nightmarish world. This can lead to some really creative plotlines and character developments.
In the 'naruto vs ichigo death battle reaction fanfiction', it's difficult to determine a clear winner. Naruto's ability to use chakra and his vast array of jutsu like the Rasengan and Shadow Clone Jutsu are formidable. However, Ichigo's strength, speed, and the unique powers of his Zanpakuto, not to mention his Hollow form, are also extremely powerful. The outcome would likely depend on the specific circumstances of the battle, such as the location, the characters' mental states, and any unexpected twists the author might throw in.
