There was a US Multi-Bot commercial--not only do I remember seeing it (as well as the Roboto one), but I had it burned to a CD-ROM. Sadly, said CD has gone missing or I'd upload it.
This is the closest thing I found to an english Multi-bot ad
Is it just me or are these the most non-violent action figure ads ever? I mean, hardly any of these toys actually hit each other XD
The Clamp Champ vs Ninjor ad does exist. I own it, it came on a vhs tape of 80's toy commercials. The ad is influenced by the film enter the dragon which is pretty cool. It's clamp champ walking around a bunch of mirrors w/ ninjor hiding amongst. Champ uses his Clamp grabbing one of the mirrors to find ninjor.
