This time we have in fact a 2-part web comic/manga which seems to be linked to the events of previous Generation Selects Star Convoy and Seacons stories. In part 1 we can see a flashback with Convoy/Optimus Prime and Galvatron face Unicron and his armada of small Cybertron Unicron clones while back in 2011. Then, we get back to the battle against Optimus and King Poseidon (Piranacon) which is interrupted by the arriving of Super Megatron (who seemed to have taken down Halfshell previously). King Poseidon now battles against Super Megatron revealing a new “combat mode” transforming his limbs into weapons, but he’s defeated easily by the upgraded Decepticon leader.
Part 2 reveals the next battle. With King Poseidon out, now Super Megatron and Convoy/Optimus Prime clash. Optimus uses his silver Matrix and becomes Star Convoy again. He transforms into a new battle station mode (which can be recreated with the toy) and defeats Super Megatron. But the treacherous Megatron forces Optimus to hand him the Matrix in order to save some innocent inhabitants. Now, Super Megatron powers up again, and a second alt mode is revealed! A new tank form which seems a homage to Ultra Megatron (also seen only in the old G1 TV Magazine Battlestars: Return Of Convoy pages).
This new alt mode gives us a lot to think. So far, many of the new alt modes, combinations or configurations seen in these comics are possible to recreate with the toys. Could Super Megatron toy also transform into this tank mode? We can spot tank treads in the first stock images of the toy. Time will tell if this is possible or not.
