That's a little better than expected..

I muck-up a little with #2 at the top when I said 'BWII'. I should have just said 'BW'. I recognized the character from the BWII anime and I knew he formed part of Magnaboss, but he was called something else (not Ironhide). I think the US/Western version named Ironhide might've been a toy-only character. Don't remember seeing him in any cartoons.

Ah, I got tricked with the animated ones. Lol. I never realised Bulkhead was called Ironhide in Japan. In Japan, the red Ironhide was Armourhide (I didn't know that either...).

Bottom 1st; I knew I'd seen him before. He was definitely a Decepticon in the Armada series, but he went by another name that I couldn't remember. I thought he might be Armourhide, because in RiD/Car Robots (I'm surprised how much I know about that series despite not being a fan), there was an Armourhide which formed one of Ruination's legs, and I figured the Armada character might have been based on that.

Yeah, besides those, not much surprises.
