...could this one be the answer? No, maybe not. But it is worth a shot.

HK-47 walks in with HK-87 elsewhere and he sees a bloody tendril in midair. Burst!Gaster is not visible to the naked eyes, not even to "stand" users. (He's not a stand, you know?) But apparently Majora can see him just fine.

Burst keeps her mouth closed and signs to classic Gaster, [Why did a Temmie go through a portal here?]
