Trion is a one time powerup given by an alternate deity separate from Cyttorak.
8th day juggs is also one time, but involves Juggernaut taking Cyttorak's power by force via pure willpower, forcing him to sit in the backseat for a change while he takes full control.
It's the only amp he can access on his own, everything else are powerups that we're handed to him.
8th day overall is probably too ambiguous for them to touch upon it anyways, plus, Knuckles time travelling is a far more straight forward win con than Juggs having internal arguments with his demon, when it comes to the actual fighting segment.
