Torso, arms (modified with Lego weapons and Lego hands)
Waist from TFP Starscream
Legs from TFPBH Starscream
Backpack from Constructbots panel piecesand Lego pieces
Crossbow from Lego weapons modified with hand pegs.

After buying Windblade, I cut the waist off and added the TFP Starscream waist to the torso. I used a lot of super glue and plenty of sanding to give the figure a smooth look. The legs fit perfect with the TFP Starscream. They are from the Beast Hunters Starscream. The backpack/jetpack from Legos anf Constructbots panel piece. Swords from TFP Wheeljack and Generations Blitzwing. Crossbow weapons from Legos.

In the end, I give you Nightbird.
