Tried to investigate the mystery why Odie's name was Magyarized to Ubul in the comics. To make it more messy in the Hungarian dubbed movie they went with the original Odie.
Ubul is in fact a Hungarian name, quite an old one, never used however, so much that I believed it's gibberish, means nothing. It is suggested it has German origin, goes back to Hugbald - Ubaldo forms. So I'm guessing it came with a couple of knights in the first centuries after our kingdom formed, and some now obscure historical figures had it too until it went out of fashion uhh... sometimes.
I did not find explanation why it was picked. Maybe it sounded a bit silly for the translator, and guessed it'll suit the Hungarian ear better, then Odie.
