I was wondering what size Energon Swoop is, I've looked around the net and I can't find anything else but stock photography.. How tall is he in comparison to say... Classics Grimlock?
Energon Swoop is essentially deluxe size, but the difference is in the aesthetic when comparing/contrasting between lines (such as Classics Grimlock). Swoop looks just a tiny bit more blocky and cartoony when compared to a Classics style figure that has just a little bit more detail. That being said, I do think he'd make a pretty good stand-in for a Classics Swoop. I sold my set a few years ago though
This picture might help you judge. Well that is if you've got Energon Downshift of Deluxe Optimus Prime to compare it to.
Not the greatest comparison pic, but he is actually pretty tall. Taller then Classics Grim and the average deluxe at least.
