Worldgender is the state of having multiple genders with such complex relationships and subgenders that it feels like the genders make up an entire world or planet together, each gender affecting the biomes and other features of this world/planet. Someone who is worldgender may attempt to create a world/planet with their identities to describe the role each one plays in their gender. There is no limit to the amount of genders that play roles in these "worlds".
The original worldgender flag was made by Tumblr user beyond-mogai-pride-flags on June 4, 2018.
An alternate worldgender flag was made by FANDOM user SingedGnome on January 15, 2021. The circle on the flag represents the world of a person's gender and the gradients represent the genders affecting each other.
