When is that stated?
That they are jndeed the same version and not just lookalikes
Like any g1 designed optimus
Eg war for cybertron,marvel optimus and many more
he says it right here in TFCC Chapter 2
he is specifically talking about the events of Cybertron/Galaxy Force here
Also he's a multiversal singularity anyways and this comic is where that whole concept started to be established, at the time it was meant to be that he was the exact same guy in every universe but this got changed later on and it's more like different avatars in each universe. Either way it doesn't matter as we have it confirmed it's the same one from Galaxy Force
And the comic opens with him hopping through universes at will explaining why he would be in both series
Marvel, Cartoon, etc are all different Optimuses from different universes
So how did optimus go from what he was in armada
To being planet lv in energon.
It's one continuity so what caused the increase in power? And what's the feats which place energon characters that high anyway
He dies in the process but he stops a planet busting blast from hitting the earth in Armada so even then he was way higher than cave wall level or whatever else you're claiming. I don't remember all of Energon too well but he is in a new body there and even if he wasn't it's....not like series don't give characters new feats as they continue anyways?
@Crimson Dragoon also mentioned Energon Megatron also having a planetary feat but I haven't seen Energon in ages
Regardless, Galaxy Force on its own has much better feats. Characters growing to the size of planets, characters surviving inside a black hole that was casually destroying planets, the comic feats just take them hilariously higher as it boosts the high tiers to galaxy level and changes Primus' feat from a universe level one to way beyond multiversal
