BUR #21445 has been rejected.
create alias protagonist_(digimon_world) -> mameo_(digimon)
create alias metalgreymon_virus -> metalgreymon_(virus)
We don't know his true name, he is mostly know as "Mameo" in the Digimon Community since a character in Digimon Next Order gave him this nickname.
Putting brackets in the MetalGreymon Virus tag to make it easier to use.
