Hopefully this will clear up some of this fucking dumpster fire...but knowing my luck, this will probably end up doing the opposite.
First of all... Basic possession principles and logic
I know what you're thinking: "Cloud, what does this have to do with Axol's corpse?" Just, hear me out. When an entity is subjected to possession, their body is completely taken over by the possessor. There are people who think that Axol's body was in SMG0's USB, and that Zero had shapeshifted to look like Axol/created a clone. This is actually impossible. Anyway, if the host's soul is destroyed, the possessor is supposed to die as a result. However, if the possessor knows that it is going to die, it can bail out of the host body at the last second to avoid death. This would explain why James has stated that "The 0 story is far from over".
Next point: Why there was no funeral scene for Axol
Tl;dr, there was no body. In WOTFI 2021, they fight against SMGO while he's still in Axol's body. When Melony performed a technical assisted suicide on Axol's soul, it compromised the body. Therefore, if what James said is true(which it probably is, considering how James is held in rather high esteem), SMG0 bailed out right before Axol's body disintegrated. I find it likely that SMG0 pulled a "Personal Fuck You" on Melony by disintegrating what remained of Axol's already desiccated body. Therefore, necromancy, 1-up mushrooms, Phoenix Down, or whatever other "strictly mortal" methods of resurrection there are will be useless, because there is no body.
What to expect in the future regarding Axol
If Axol IS going to be revived:
If Axol is NOT going to be revived:
Well, if this outcome happens, we might as well just grin and bear it, knowing that our pleas will all be in vain.
Sure, he may be gone, but I'm certain that he is going to live on in fan-works, such as fanfics(such as one that I'm currently working on some beta drafts for), fan videos, fan submissions for collab specials, fanart, et fucking cetera. And who knows, maybe Luke and Kevin will change their minds and bring him back.
