Undyne is a person who is active as a royal guard
in the underworld.
The attack type is Javelin Throw
(attack by throwing a blue glowing spear).
In the in-game speed run route, if you kill,
you will resurrect as Undyin the undyng and try to somehow stop
the protagonist (including mettatone NEO).
At this time,
the identity of the one eye
that Undyin was hiding is revealed. Like sans,
light comes out
out of the eyes.
This is the shape of the window that Undyne
himself has.
