Notes

• Loader never transforms in the movie.
• The article that initially confirmed the Superfund Decepticon's existence also inexplicably predicted that the truck was Shockwave's altmode, which obviously did not come to pass. The same article also makes a joke about Ironhide that kind of hurts now.
• Loader was established as the same character as the Superfund Decepticon by the Facebook edition of "Ask Vector Prime".
