Made from a Unicron and a Thundercracker (ducks waiting for arguments over which Seeker made Cyclonus/Scourge in the movie )

Attachment 1507

To make Scourge I trimmed the following off a Robot Heroes Unicron:
horns
collar
wrist spikes
wings
heel
the tips of his side and front toes.

Attachment 1508

His head missile is the tip of a Robot Heroes Thundercracker gun (if you don't have a spare Seeker I'm sure the tip of one of Unicron's cast off wings would do).

Scourge's wings are cut out from a toothpaste tube.

Attachment 1509

The obvious next step is Cyclonus but at the moment I am at a loss as to what to use....
