For those wondering what's going on in Starscream's pack-in comic, before I get into that, there's a three-page prequel that was posted on Takara's website that I'll go into first, along with summaries of the prequel's events (click each pic below to see them at full size):
"LG-18 Armada Starscream Super Mode Prequel 1" (LG-18アルマダスタースクリームスーパーモード前日談1)
Having lost his old part-time job, Armada Starscream is lamenting having to find a new one when he witnesses Windblade collapsing nearby. She tells him she can't go to work in her condition, so he offers to take her place, only to learn once he gets there that her job is at a maid café. He's left regretting his fate in life once more while the manager, the local Starscream, berates him for not welcoming customers loudly enough.
Armada Starscream questions why they agreed to hire a man at a maid café to begin with, so Legends Starscream reveals that he's not actually running a little sister-themed café: they're normally a little brother café featuring male maids. He explains that he only hired Windblade because he felt sorry for her, lost and confused as she was, and Armada Starscream admits that his counterpart is actually a nice guy. He then notices Windblade arriving and prepares to leave, but Windblade isn't her usual self... she's regained her memories, and seeks to destroy the Legends Universe again!
"LG-18 Armada Starscream Super Mode Prequel 2" (LG-18アルマダスタースクリームスーパーモード前日談2)
Having come to her senses again, Windblade tells Starscream about the Legends Universe's creation at the hands of the Zamojin, further explaining that it's an experiment in "spirit energy" that lets the Zamojin absorb the spirit energy of its residents to grow stronger. This energy is generated by desire, and Armada Megatron's recent unquenchable thirst for Transformers toys is threatening to make the Zamojin strong enough to take back control of Windblade. As she despairs to Starscream that she doesn't want to become her old self and destroy the world she's grown to love, the two are approached by the glowing form of Swindle.
Swindle tells them that he's a Mini-Con native to the Legends Universe, where his people live disguised as toys, and wants to help them protect his world. Starscream recognizes the Mini-Con as a toy he'd had on him—Megatron had given it to him earlier as a reward for a job well done, an occasion that had felt strangely familiar to him. Swindle then lends Starscream the power of the Mini-Cons, powering him up into a new form. He valiantly sets out to put stop to Megatron's aspirations, but not without promising Windblade that if she does fall under Zamojin control, he's ready to give up his life to stop her. Meanwhile, in another world, Alexis is at the beach with her friends...
And now for this figure's pack-in comic, with the conclusion of this little story:
Having tired of collecting mere Mini-Cons, Armada Megatron has moved on to stealing all kinds of large and rare Transformers toys from the people of the Legends Universe. As he's announcing his evil plot, he is attacked by Armada Starscream, who asks him to give up on his ambitions, explaining that the spiritual energy generated by his desire only serves to power up the Zamojin who created this world. Megatron refuses to stray from his chosen path or give up his collection, instead accusing Starscream of betraying him, and the two do battle. Suddenly, Starscream's worst fear comes to pass: everyone's spirit energy has strengthened the Zamojin enough to restore Windblade's original purpose as a tool for destroying the Legends Universe!
Refusing to let this happen, Starscream readies his Null Laser Cannons in an attempt to destroy Windblade. Armada Megatron recognizes the situation, explaining that Starscream was once killed channeling all his energy into this same attack while fighting a great evil in their previous dimension, so if he goes through with it, both he and Windblade will die. Fortunately Alpha Trion has a solution, using his ultra-drill to summon someone close to Starscream from his home universe—Alexis. The sight of the human girl causes Starscream's memories to resurface, and he calms down and accepts her offer to return home with her. Sick and tired of the Legends Universe, Armada Megatron follows suit through the portal, leaving his stolen toys behind. With Windblade back to normal and the toys returned to their rightful owners, everyone's happy... until G1 Megatron asks for the original owner of Armada Megatron's ultra-rare Unicron of Light, and everyone present tries to claim it.
off-centered? It really bugs me.
