Judging by the size of an average legends figure, I'm guessing this guy will be roughly deluxe-sized. That's pretty big, all things considered, and will let him really tower over the other legends figures.
I'm willing to bet that we may get this set repainted in the classic green and purple and used as an offering for Devastator in the inevitable Universe 3.0 line. They did it once with the Six-Builder mold in Universe 1.0, so why not.
I'm really hoping that Hasbro gives us a supreme or ultra class cityformer to accommodate the legends figures. It's the best way to go if they don't want to risk making a
huge toy that costs around $100.
