THIS IS SO STUPID I KNOW BUT HEAR ME OUT ON THIS(talking about B.O.Y.D.'s Ethnicity and Nationality btw as well as species)
Gyro Gearloose doesn't have a specific ethnicity,tho,I like to think of him as Greek, considering his name,"Gyro",which is also a name of a Greek dish, called "Gyro"(I know this is stupid BUT LET ME BE...)(this is a HEADCANON btw) also don't you dare bring up the fact he's named after the short term "Gyroscope" in engineering and physics😡(I know he's canonically named over that but let me dream alright...)
SO let's say Gyro is Greek(which is false/unconfirmed),then we have Dr.Akita, who's very much clearly Japanese,that aside,we know both of them created B.O.Y.D.,which could leave the possibility of saying B.O.Y.D. is half Japanese and his other half is unknown (considering his "parent" is from there)
Then, let's move on to the information we know from B.O.Y.D.
we clearly know that he's an African Grey Parrot! And those parrots are also known as,the Congo Grey Parrot! (Which they also originate from there too!) So,that could also leave the possibility of B.O.Y.D. being Congolese (or at least, African,but the closet assumption is Congolese)
He was also created in Tokyolk(which obv is Tokyo),Japan,which makes his Nationality Japanese,his Ethnicity African(Congolese) and if we consider his ethnicity to depend on his "parents"(creators) too,then he's a half Japanese ethnically African(Congolese) Nationally Japanese African(Congolese) Grey Parrot!(And if my stupid connection to Gyro being Greek was correct,which will never happen but let's say it's a hc,then he's also half Greek!)
Btw this is NOT counting his adoptive family!!(Drake family,which most likely are American)
Anyways–
All this information is prevented with stupid proof too!!
Feel free to correct me,but again this is all a stupid connection and just hcs!! So they're not facts or canon at all,I just found it fun to look deeper through his character considering he's a robot,and since I have a hyperfixation on him^^
