The exploration of new worlds is also common. As Sonic is from his own game - based world and Goku from the Dragon Ball universe, fanfiction writers often create new settings where both characters can interact. This could be a merged universe or a new dimension that they are transported to. These new worlds add an element of mystery and adventure to the stories.
It's really hard to say. Goku has the power to destroy planets and reach incredible levels of strength with his Super Saiyan forms. However, Naruto has the power of the tailed beasts and his own sage mode which gives him a huge boost in power. And Sonic, while he may not have the raw power like the other two in terms of destruction, his speed is so great that he could potentially outmaneuver both of them. So it really depends on the situation and how the author writes it.
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.
Well, it's not straightforward to say. Different comics might portray their speeds differently based on the plot and creative decisions. So, it varies.
The canonicity of Sonic the Comic is a bit ambiguous. It might be considered canon within certain contexts or storylines, but it's not a straightforward yes or no. Different developers and storylines within the Sonic universe handle it differently.
