Memoryhead - one of the most mysterious amalgamates found in True Lab. So mysterious it made me wonder of it’s origins, and soo…
Theory time!
I bet I am not the only one who noticed that Memoryhead looks like bunch of skulls creating one bigger skull. The aesthetics of eyes (black eye sockets with pin sized lights), faces and teeth greatly resembles those of skeleton brothers.
In this case are those skeletons too? We don’t see any other through a gameplay beside brothers and Gaster - if Gaster is a skeleton that is. Shouldn’t there be more of them? This certain lack of other skeletal representatives (beside bros who just happened to appear in Snowdin one day) made me wonder if Memoryhead isn’t the reason why we don’t see them. Maybe it’s simply made from almost every skeleton that survived underground.
So there are few options how skeletons ended up in True Lab:
1. If Gaster was experimenting on skeletons those could be his first failed attempts to create them or using them as test subjects. Sans could be the first one that didn’t turned out bad.
2. They were skeletons working there, just like Sans.
3. Maybe they had fallen and since they were just there in the lab they could be the first experimental patients whatever they were failed experiments or workers or civilians
This could be the reason why we have seen only Sans and Papyrus and why nobody have seen other skeletons or even mention them. They are all stuck in Lab and for some reason, whatever happened Sans and Papyrus are the only ones that survived the fate of their brothers.
Interestingly they speak in code similarly to Gaster and they an be heard only through phone. What’s more, their attacks look like Gaster’s (or skeletons) faces. Are they remembering how he looked? It is after all a MEMORYhead, it is possible it’s channelling their experience to fight.
I can’t English.
