'Tis what happens when a comic that isn't trying to sell toys is forced to try selling toys, but still tries its darndest to continue not doing that like it had before and after.
My favourite part about TR's comic run was that just before it started Optimus decapitated Galvatron (things got kinda Bayesque for a moment) and everyone rightfully went "oh ofc Galvatron's coming back as a Headmaster" because he was in the first wave of TR toys and he lost his head right before the TR comic line started.
And then... it just didn't happen. Like the setup was right there. It was perfect, and just didn't happen.
A close second was that they did use Sentinel/Infinitus and Blackrock/Alpha Trion but got weirdly indignant about actually selling the toys in the line.
Sentinel showed up with his old (non-toy) Megatron: Origins body wearing black modular armour over it that vaguely looked like his TR toy but not really (the thing doesn't have any black on it) and Alpha Trion was just normal IDW Alpha Trion without even a hint of his unicorn/lion mode from the toyline.
Only they had Infinitus cut off his head and wear his body so you kinda had some representation of the play pattern only not really because the Alpha Trion body didn't look like the Alpha Trion toy. And then Infinitus gave Alpha Trion's body to Blackrock/Sovereign who then turned into an Alpha Trion head.... for reasons presumably to sell the toy, only it didn't look like toy.
Meanwhile Galvatron was still headless, had a Headmaster toy on the shelf in the line the comic arc was named after, and just stayed dead.
It's almost art in how IDW both did and didn't want to play along at the same time. Like f'in Gollum was writing the comics for four months.
