IDW Editor-in-chief Chris Ryall has updated his blog with the variant covers to #5 and #6 of All Hail Megatron, both drawn by Casey Coller (who drew the "Killing Joke" homage cover and to-be-released Spotlight Blurr) and colored by Joana La Fuente. Cover to #5 has Springer and Blurr and one unexpected but familiar Autobot. Cover #6 has Autobot newcomer Drift and two other 'Bots causing some "messes".
