I figured I'd also shoot down some other misinfo since I noticed something while rereading the FunPub comics.
One of the most common things you will see in Transformers downplay is the constant claim that Unicron is beaten by weaker guys, therefore he isn't anywhere near as strong as FunPub states.
There's a lot of reasons this doesn't hold up though.
The primary reason is, of course, that the Transformers multiverse as a whole did not truly become a formalized concept
until FunPub started their comics...in 2005. Decades after the concept was established but not fleshed out in Marvel. 3H Comics would also delve into it in 1997 and other comics, and admittedly I haven't gone through all these yet. They're far more obscure than other material, but the comics focusing around Shokaract involve parallel timelines intersecting and timespace of multiple universes being damaged by
Unicron's destruction in the movie it was actually him being blown in marvel g1 my bad . So thus reason 1 is quite simply, FunPub added a lot to Unicron's lore that simply did not exist in years prior.
The next reason is that Unicron hasn't really ever "lost" (such a thing is always temporary because he can't really die) without some kind of powerup or artifact involved. For example in Marvel, he was destroyed by the Creation Matrix which contains Primus' essence which is essentially his allergy. In the Armada comics, he was knocked out of the universe by the Mini-cons who allegedly (it is debatable) had universal power. His collapse into a black hole in Energon is particularly notable, however FunPub's comics clarify that this only happened because his body was not at full power. Although it's debatable which version of Unicron this even is.
Unicron's actual losses are as follows
1. Being tricked by Primus at the dawn of time and trapped in a physical body, separate from his original Astral self. This is the Unicron we have seen in every comic since, and it is weaker than his original form that devoured the Old Realms.
2. Shoved through a black hole by the 13 in Dreamwave. This was weakened Unicron however, as the 13 came into existence at the very beginning of the multiverse, not before it like Unicron and Primus. His other losses follow this pattern, weakened Unicron comes in contact with the Matrix or something else that can drive him away. He isn't ever overpowered. Now, officially Movie Unicron is
not supposed to be connected to the god-mind and is merely supposed to be a machine made in his image out of visions Primacron received. However this is contradicted by the 3H Comics, which explicitly showcase damage to several universes that occurred from Unicron's essence leaking out after his "death" in the movie. Additionally, Takara's manga treats movie Unicron as multiversal, as it is this version that appears in the Legends Manga. It's a bit confusing, and official sources seem to all disagree on it.
3. Cut apart by Nexus Prime with the Star Saber and Terminus Blade, when Nexus was reformatting the entire multiverse. This is notable, but it has its own caveats. For one, Unicron still wasn't killed by this. Two, according to Sorenson things like the Legends manga weren't affected by The Shroud....this confusingly means Unicron both
was and wasn't cut apart, at the same time, and that multiversal Unicron is still running around.
This makes no sense at all but is the only official confirmation we have. Three, this is still weakened Unicron and not Astral Unicron. Considering these swords can't kill current Unicron it's unlikely this would have even worked on Astral Unicron. The Astral Plane is the highest part of existence currently canon to Transformers, and very little has been seen of it.
So tl;dr Unicron "losses" are typically the result of people exploiting the weaknesses of a less powerful body than his original form. Even the Singularity caused by one of his deaths, that threatened the entire multiverse, he still survived sitting at the core of. People like to downplay this feat as something outside of Unicron's power that only happened because the balance was shifted. The "can only be in one universe at a time" rule was also contradicted by FunPub's own material, as Unicron existing outside of time and space effectively meant he can be as many places as he wants at once. In fact even Vector Prime can do this, but he
chooses not to so as not to destabilize time.
I could go on and this thread has really boiled down into a Unicron respect thread with other characters mixed in lol, but I think this covers enough.
