create implication blue_spirit -> zuko
The Blue Spirit is Zuko's masked alter ego in Avatar: The Last Airbender. This tag is intended for posts depicting Zuko specifically as the Blue Spirit, so it should imply the Zuko character tag.
This should not be an alias, since blue_spirit describes a specific identity/costume rather than being a direct synonym for Zuko.
