Were Umaro and Gogo in the original FFVI Japanese version?

The rumour, wherever you heard it from, is baseless. It really wasn't until FF7 that we started adding things to games that came to us. Ruby and Emerald WEAPON, if you didn't know. But yeah, the only things changed, to my knowledge, was the censoring on monsters, to make them more... kid friendly, I suppose. lol.
