Major Metallitron?

[Herms]

It's weird how they couldn't even keep the rank the same. Sergeant, Major, agree on something will ya!?

I think that was done in the interest of alliteration. Strange as it may be, if they had to change the name and rank, that didn't go over too poorly with me.

But...there's no alliteration in his name in Japanese (Metarikku-gunsou), so I don't understand why they'd want to suddenly make it that way. They might as well call Black a Brigadier General, or Bibidi a bishop.

Anyway, his rank is 軍曹/Gunsou, "sergeant". A major in Japanese would be a 少佐/shousa.

This may seem hair-splitty, but the simple idea behind Muscle Tower is that the further up Goku goes, the higher the rank of the opponent. So he fights Sergeant Metallic, goes up a level, and meets Master Sergeant Murasaki.

What was his deal? Anyone else wonder if he was a prototype Android of Gero?

I don't know. I sometimes wonder whether Major Metallitron (yes, I use the dub name, sue me ) was an older or newer model than Android 8. Was he 1-7 or 9-12?
