Hey guys, I thought I had read all the important IDW stuff, but apparently, I'm missing one of my favorite character story arcs. I've read the Megatron Spotlight where he has his Stealth Bomber form. But apparently there is a whole story where he is damaged and gets his new MTMTE form?? What series is this? I would love to read up in that? Thanks so much
Sounds to me you might also have missed a big chunk of the Robots in Disguise book by John Barber (season 1)? Spoiler Before getting his MTMTE body his stealth bomber body first gets repaired into something a bit more G1 looking.
He damaged it fighting the D-Void in the Chaos/Heart of Darkness storyline. (D-Void being some dark God combiner made up of all the Decepticons) He came back in Transformers Robots in Disguise after hiding in the wilderness for awhile. He was arrested then broken out of prison. He had a new more G1 style body built, then had that body damaged in the Dark Cybertron storyline. He had the rebuilt G1-ish tank body at that time. That was after the stealth bomber time period.
After the Chaos event, Megatron returns in RID 12 (I think?) in his bomber body, but heavily damaged. A few issues later he changes to his tank body he has for the duration of Dark Cybertron, then changes to another body when he joins the Lost Light.
