What is the strongest version of Starscream that Gigan can defeat?

[Xadlin]

Since, I randomly on a whim saw a Gigan pic recently, and knowing his tratiourus nature I saw a parallel.

From what I've seen from some movies and comics, I lean that starscream is more powerful.

So, which version of Starscream is weak enough for gigan to defeat?

Also this is double bladed gigan, since I assume thats his strongest form.

Does Gigan stops at comics, or does any of the tv-shows and animated movies have something I missed?

what does Gigan scale to? Not familiar with Godzilla feats, probably to Godzilla destroying that meteor in final wars at least right?

he should beat the TFA and Prime cartoon versions, probably beats the g1 comics as iirc they don't get crazy for the regular characters feats, G1 Cartoon StarScream might get the planet level scaling? G1 is weird. Loses hard to Unicron Trilogy Starscream who should get the multi-galaxy level scaling as the Vector Prime in Galaxy Force is the same one in the TFCC comic who could counter galaxy destroying entropy waves. I don't know exactly where Alternity StarScream sits, he's not like the other Alternity so I can't flat out say he's multiversal, but he can do esoteric shit like destroy time and even avatars of Alternity are able to cut chunks out of the moon.
