IDW Shockwave just hangs around and looks cool, but never actually does anything of value, in that sense he is more like his cartoon counterpart than his Marvel comic one.

As for the possibility of ravage surviving the issue, well that would be just stupid given that loss of head (between RID and the Bay movies) is now the most common cause of death for Decepticons. I'm sorry if Ratbat can be killed by being run through and Ravage can't be killed by unexpected decapitation then I call major shenanigans and favoritism on the part of the writer.

Anyway It's interesting how the Autobot characters always seem to narrowly avoid death in IDW comics of late.
