Super duper rough sketch of an antagonist group for both a sci-fi fantasy series I'm creating and making appearances in a Sonic (Archie) RP as well. Again very rough draft.

They're basically a mercenary/warband of elite pilots consisting of cyber-augmented bats. Influenced heavily by the Chaos pilots from the WH40k book by Dan Abnett, Double Eagle, in particular the main 'villain' Khrel Kas Obarkon (Chieftain of the 5th Echelon, which was of the Anarch, and so sworn to he that is Sek!). There's more to them than just that, but that's the general idea behind them.
