Also, last notable feat in the series that I can recall, when the Decepticons open the Plasma Energy Chamber, its energies disable the Autobots by overloading them, and it threatens to cause the Sun to go nova (which is kind of terrifying, considering the sun shouldnt be anywhere near large enough to go supernova)
To save the Autobots, the Earth, the Solar System, and potentially the universe, (as its implied that the Plasma Energy could just keep going out into space after destroying the sun, with the Autobots having no idea how far the reaction will carry) Spike and the Nebulans use the planetary engines Galvatron built into Cybertron to absorb all of the Plasma Energy, rerouting ALL OF THAT POWER directly into Vector Sigma, reenergizing Cybertron and beginning a new Golden Age.
I'd honestly consider it a decent durability feat for the Autobots that they all didnt immediately melt from such energy, however it still overloaded them of course, as for the energy causing the sun to go nova, i havent yet decided, but said energy being absorbed by Cybertron itself is a pretty good durability feat for the planet, at the very least
Theres possibly others before this but i remembered this one first as it was the series finale
This combined with the Unicron feat from the comics, means I think for now as an assumption its safe to put the upper tiers of the G1 cartoon and comics at star - large star level
Could be revised later, but all the super high tiers seem to be around this point at least, with the Underbase making stars go supernova by passing through, and Unicron being able to consume stars, with the Matrix being able to destroy him completely, alongside the Plasma Energy Chamber unleashing enough power to cause the sun to go nova as well
I dont know if any specific characters scale this high, save for
potentially powermaster optimus, but thats a big potentially considering the state it left him in. But, considering there are still characters stronger than him, I dare say I think it's possible
potential contenders imo are:
Galvatron (possibly, at least in his prime, considering how much stronger he could be than Optimus), Starscream (having absorbed the power of the Underbase, meant that he had to be able to survive it in the first place, although said power still eventually destroyed him as well)
its a pretty short list, but i would expect it to be
Edit: As i said a few pages back, i wish i could find the energy requirements to disrupt the the equilibrium of fusion within a star, as i think that could potentially provide a lower end to the Underbase's star busting feats, as well as maybe just be useful in general
If we knew the energy to spike fusion within the core of a star and cause it to blow
itself apart that would serve as a good alternative to the idea that the Underbase must be casually emitting supernova levels of energy every second or something
