how did x!sans survive a hit from the gaster blaster? sans should have karmic retribution.
He just dodged it, it wasn’t really hard for him xD
Also, as far as I remember (HANDPLATES SPOILER?) Handplates!Sans doesn’t have KR yet. He actually used a blaster against Gaster time ago but he only made 1 damage on him, with no karmic retribution at all. I think he’s going to get that ability in the near future now that Gaster is gone, but that’s up to Zarla.
Regarding X-Hand, after all that had happened, don’t expect to see that ability either :)
