Some very interesting facts covered this time, I feel! Which one is your favourite, what holds the most potential for further insights into Undertale's lore?

[martensforlife]

Honestly, Gaster isn't a secret anymore.

He's just mysterious.

Here is a good theory video question, why does no one in Undertale know about The River Person? I tried calling multiple times near the area but no response, and Undyne only mentions swimming up and down the river, no River Peron. There is something weird about them.

For the Chara one, it's because when you kill a monster, it's Chara's LV that goes up, not Frisk's. Chara even confirms this on the no mercy run.

Other similarities to Earthbound:
-The sudden contrasts between comedy and a serious plot
-Chara's Locket and knife are found in present boxes, in Earthbound all items in the overworld are contained within these
-The obvious symbol on papyrus clothes
-The final boss is defeated by "calling for help" like you defeat Gyigas by "Praying" for help in Earthbound
-Flowey taunts the player into calling for help in the final fight, similarly to how Pokey does in Earthbound during the final fight
-In earthbound, in the final fight, you contact all the friends you made during your adventure to lend you their strenght, in undertale you don't call them, but they come by themselves to lend you hope

''Sans is Ness''
No shit.
''No, not really''
Thanks godness.

Fun fact: 98 robot is not a old mettaton it is mentioned in the art book that they are a robot from the original hotlands along with more robots in the book and some cyborgs but they decided against the idea thinking mettaton should be the only one

Last time I was this early Asriel was still alive

I'd like to point out you yourself, in the past, stated that 'ruined castle' in the overworld is almost certainly the city Papyrus drove his bed-car through. A bit disappointed there wasn't anything new to me here, but I guess that's the nature of only having one game.

[Strabius]

In the undertale art book, tiny fox mentioned that the unused robot sprite was from when he originally planned to have robots scattered around Hot Land, but for mettaton was created as a character, it stopped making sense to have so many robots, because they would have overshadowed his importance as a character.

[hockeater]

You do know that based upon the mirror in the genocide route saying ''it's me'' as opposed to ''it's you'' in any other route chara is pretty clearly the narrator right? Also only evil when you as the player force feed it to them by murdering everyone they used to care about for power?

[fishyfishyfishyakabs]

maybe that "soul" in the True lab is just a power core, like Mettatons

[Al_Marie]

"Sans is ness... No not really"

Boi XD

[jcrossx]

I always thought that the “castle” on the surface was a city

[infinite_sun_rays]

Underlab: "for whatever reason, he didn't go through with it"
Toby Fox: "I forgot to do it"

[CheerUpCrewcut]

The most amazing thing in UnderTale is how little love the dogs get. The dogs are the best characters!!!
