The main characters in 'Planet Jackson' fanfiction can vary widely. Jackson is a given, but then there could be a scientist character who studies the unique phenomena on 'Planet Jackson'. There might be a love interest for Jackson, either someone he knew from Earth or a native of the planet. And don't forget about the antagonists. There could be a powerful being on the planet who wants to keep Jackson from achieving his goals, whether it's exploring the planet fully or helping its inhabitants. These different characters interact with Jackson and drive the story forward in various ways.
In many 'Planet Jackson' fanfiction, Jackson himself is the central figure. But there could be other important characters as well. For example, a local guide on 'Planet Jackson' who helps Jackson understand the planet's secrets and mysteries. Or perhaps a rival from Earth who also ends up on the planet and tries to compete with Jackson for resources or power. There could also be a group of rebels on the planet who Jackson either joins or opposes, depending on the plot of the fanfiction.
Another character that could be a main character in some 'after phantom planet' fanfiction is Frostbite. He's from the Ghost Zone and his relationship with Danny could be further explored.
