I'm really late on this one since it's past September 22nd, but Kirby Super Star Ultra has turned 15! This game featured the debut of Galacta Knight, which we all know is the greatest warrior in the galaxy.
However, in-universe, even after Galacta's disappearance long time ago, there has been suspicions lying around regarding Cyon himself. It felt as if he knew a past life. Fought with a grandmaster title that was soon lost to another strong warrior, eventually crossed timelines to reach a heaven at the brink of its fall, and resealed again... freed... and absorbed by a dark-winged disaster in another timeline.
Cyon seems to show this remnant of power in his most critical moments of his life, especially when battling big threats and allying with Satanael in some cases. And he's not to be messed with in this state.
I've played around with the idea for a while that Cyon may be potentially a reincarnate of Galacta Knight, especially on my WiKirby userpages and in Cyon of Gaia ramblings on Discord. I think it's pretty much no secret that this is actually something I made canon to Cyon of Gaia lore.
Seraph of Aeons ELYSIUM, another knight that crossed into a fallen heaven with Satanael, is also still Galacta Knight/Aeon Hero, just jumping through timelines after being defeated for god knows how long. True Arenas, time attack modes, and even Super Kirby Clash. It all keeps getting to him, until he crossed so many timelines he went into this ethereal world. And about the fact that ELYSIUM is his true name and Cyon's full name in this world is EleCyon... heh, heh. I think it's up to you now.
Anyways, happy 15th anniversary to Kirby Super Star Ultra, and happy birthday to the greatest warrior in the galaxy. See you again for some more Cyon of Gaia content, as well as more fan art.
