what are seekers?

I know the term is used to refer to Starscream’s frame type but I never quite understood it. what are they seeking exactly?
in tfp, Starscream calls them “Energon Seeker” which doesn’t really explain much – I mean they obviously aren’t miners, and Cybertronians have advanced technology to find energon so… what are seekers for?
I know this is probably not what the show intended (but that’s the fun with headcanons – it doesn’t matter!) but my favorite theory is that they aren’t really called seeker at all – I think it’s just grounders being too lazy to translate a Vosian word.
I’ll explain – back in the days of ancient Rome, during “the Great Revolt ”, the jews had a unit (for lack of a better word) called the Sicarii, they were called that because of the small daggers they carried that were called Sica that they would use to silently stab anyone who was suspected to be a traitor or to align with the Romans.

<this is what this Sica looks like>

now Starscream obviously doesn’t have anything that resembl-

oh.

I headcanon seekers to be some kind of elite assassins used for dangerous & important jobs – hence why Starscream bragged about it to Airacnid…
now in any transformers universe (that I know of), Energon is both their fuel & their blood.
I think we misunderstood which one the seekers were after…

I know this might be a bit of a stretch but transformers tend to use many Roman words so… it’s not completely impossible!
