Rattrap
Nightbeat
Crosscut
Tankor

Note that these are advance place-holders, and in the past they have sometimes ended up being different names or cancelled altogether.

But if any or all of these are true, it makes for more random selections from the various eras of Transformers (but taking its cues from the IDW cartoon, if they are packed with comics like the first couple waves of Deluxes).
