It's Galvatron's more insane brother Megatard. It's actually not a bad price for a G1 Galvatron complete w/ working electronics. I wouldn't pay too much more though.
Ah yes... from the same folks who brought us Mutant Defensor. You have to chuckle, though, at these poor frustrated auction-site employees, trying desperately to figure out how a Transformer is supposed to look.
the price varies alot. I got the body with black gun for $6 shipped, just because seller was stating it's "for parts". Turns out the only thing doesn't work is the trigger on the handle(It's stuck, if anyone knows how to fix this please let me know), lights and sound both works with the chest button. And no other major issues other than regular wear. Of course the same seller sold the cannon part alone for $24......
