Sky High the Micromaster. First time an existing name was used for a new character, and started this confusion.

But both are obscure so few people try to say Micromaster Sky High is meant to be, or meant to be based on, Pretender Sky High. (Like people saying Movie Barricade is a new version of Micromaster Barricade, or many of the other examples).

I don't mind that Magnaboss is made up of Prowl, Silverbolt and Ironhide. I think it's pretty stupid that it's extended universe canon that Magnaboss is made up of reformatted versions of G1 Prowl, Silverbolt and Ironhide.
