It's up to date, absolute no need to change. But it would be great if you created a few new stories that further his character journey. No matter how much you like to rewrite I don't think it gets better than his current up to date lore. Please don't do it, please.
Or. Counter argument.
Rewrite all of Targon and remove the space parasites completely.
Hey, a man can dream.
back on topic, I honestly like pantheon being the aspect that burned away the host. it adds more to the idea that these things are powerful and that the aspect of war cares nothing for mercy.
we could see stories of how pantheon rallies his people, in spite of being the aspect people would rather not see...ever.
The problem with Pantheon's current lore is that it's pretty damn vague. It talks about Atreus, who in the end is no more, as he's fully possessed by the War Aspect. The bulk of his lore is about this boy who basically evaporates and isn't the character we know in the game, so in reality, we have next to no information about Pantheon at all. Even Varus' bio talks in depth about Varus, the Darkin, who eventually possessed Kai and Val, and doesn't focus 99% of it's efforts on his hosts (except in the accompanying material like the video and comic).
So Pantheon definitely needs his lore changed, to actually be about the character we know, and not some nameless body he's currently occupying.
