I'm certain it's not transformers and it was a bit more cool than Van Pires. I destinctively  remember the antagonist being a dragon, though. A dark cored asain style dragon like Shenron and he did transform. He transformed much like Metroplex did in the Cybertron series except folding his body where his legs came from the midsection, tail and head became the arms and his head poped out. He was like 80-140 feet long as a dragon.  I can't remeber  if his dragon alt had arms and legs or not.

Not transformers. Megatron was always a european or american style dragon, not an asian one. And he was not very big. He was a dragon in beast wars and in transformers cybertron. The latter he was purple with three heads.

Maybe Zoids? But it isn’t cgi
