Ineffable Loser

I just think it would be a neat way to bring immortal Starscream to Bayverse. Literally has his spark dragged back to living by Quintessa’s “ “ “magic” ” ” and now he can’t fucking die again, and he’s so TIRED, just make it end oh my god

Boring reason: Quintessa was just bringing back old sparks to rebuild Megatron’s army to do her bidding, but did not have time to do more that Starscream and a handful of others before getting her shit pushed in by Optimus.

Shippy reason: Starscream was brought back specifically in order to make Megatron easier to manipulate and control. Gets a brand just like Megatron and Nemesis, and she routinely makes him do things to keep Megs compliant.

In Age of Extinction KSI used Megatron’s head to code for their bots. Brains says something along the lines of “his head isn’t as dead as they thought”. Megs is able to pass on his consciousness to his new body this way.

Daytrader had Starscream’s fully intact head (even though it should be destroyed). With Starscream’s indestructible spark I say his head is all that’s needed to resurrect him. Megatron may have even known Starscream was still alive somewhere in there because he spoke to him.

Also

The Allspark can give so much energy and power for a nearly destroyed bot to completely reform a new body: i.e. Frenzy

The Fallen already stated the Allspark cannot be destroyed only transform. When the Allspark fragment mixed with the Matrix it became an all in one power source of the Primes.

In my head, the reason Starscream's is intact is because it pieced itself back together. In ROTF we were already shown that he could simply shove his arm back in place, and his frame would sort things out on its own. (Plus Bee in TLK literally gets blown to pieces and puts himself back together no problem.) I don't think it's a stretch then to think that his helm could piece itself back together as well, and possibly regrow what is completely destroyed, similar to like you said with Frenzy getting a whole body again.

Starscream has been in contact with the Allspark before, in a way, when he created his own back on Cybertron. Could make the logical stretch that he has a piece of it within himself now, and that's how he was able to reform. It is just a slower process.

I do like the idea that Megatron *knows* he's alive in there. He came back himself, he knows Starscream has the capacity as well.

Also can explain why it took Bee 5 movies to garble words out of his voice box. Such a delicate part of their system it required so much time to heal to a ‘useable’ state.

But I love you way you think of Starscream being a keychain to Megatron. Kinda like how Mimir hangs on Kratos in the God of War games.

I drew this for exactly one reason and you can tell
