i came up with dialogue for this one at the start
i didn't even know you could do bold text in descriptions (it didn't work lmao)
by the way, if you've seen that one Hard-Mode by LiterallyNoOne where it uses Chaoz Fantasy by ParagonX9, i referenced the original Chaoz Fantasy in the background a couple times
ULB by Mr. Fazbear
[HARD-MODE] by Toby Fox
[HARD-MODE] MEGALOVANIA by Divide
Dialogue:
you look tired. or nervous. both, maybe? yea, i'll settle on both.
is everything goin' too fast for you?
just kidding. i don't care.
besides, i got an old friend for you to say 'hi' to.
and hey, maybe now...
our world will finally be free from the parasite you are.
Lore:
Gaster possesses Sans' body like usual, but he also starts using way too much energy, causing Sans' bad time eye to explode in the socket. One of his eyes glows white, and the destroyed bad time eye glows yellow. Both eyes start to fracture, excess energy coming from both of them. In this phase, Sans is not at all in control, not even during the slow parts; Gaster is just mocking the player. But in the end, Gaster causes yet another explosion, and Sans' skull shatters due to the normal ULB p3 immortality wearing off. This causes Gaster to lose his influence over Sans' body, making Sans vulnerable again, and he gets hit again.
note: not sure if i'll do a phase 4 or not we'll see
