Fanfiction in the 'G.I. Joe: The Rise of Cobra' universe often explores new characters (OCs). It can give more depth to the existing story. Maybe the OCs are soldiers, or they could be civilians caught in the crossfire. It depends on the creativity of the fanfic writer.
Another interesting concept is a character - based crossover. A Joe like Snake Eyes could form an unlikely bond with a Transformer like Bumblebee. Snake Eyes' ninja skills could be used in combination with Bumblebee's speed and agility in combat. They might start off not trusting each other but gradually learn to work together as they face various threats.
One common theme is the idea of unity. Different groups, like GI Joe and other fictional teams, come together to fight against Cobra. This shows how cooperation can overcome a powerful threat.
The key is to find common ground. Both have their own groups of heroes and villains. You can start by having a threat that affects both universes. For instance, a new evil force that wants to take over both Earth (where the Joes operate) and Cybertron (the Transformers' home). This forces the two groups to collaborate.
One popular 'gi joe rise of cobra crossover fanfiction' is 'The Joes and the Autobots' which combines the GI Joe universe with the Transformers. It has an exciting plot where the two teams join forces against a common enemy.
The filming locations for the story of GI Joe vary. It could be in multiple places depending on the specific production and requirements of the project.
It depends. Certain GI Joe comics featuring special storylines, limited print runs, or signed by the creators can be worth a lot. But common issues might not have much value.
You can start by getting familiar with the characters and the basic storyline. Then, read from the first issue or a collection that provides an introduction.
It depends. Certain issues from the 1980s of GI Joe comics, in good condition and with special features, can be valuable. But not all are. Condition, popularity of the characters, and scarcity play a role.
