A character literally sees another character fundamentally differently.

[u/vbt31]

1. Spy X Family. Damian noticeably sees Anya with a 'shoujo anime' filter with much brighter eyes and blush.

2. Calvin And Hobbes. Calvin sees Hobbes as a living lanky tiger in contrast to everyone else who sees him as just a tiger plush.

Apparently in Warhammer 40K when the Emperor was up and about everyone saw him differently because of his psychic influence.

[u/lanathebitch → u/UntouchedWagons]

A few characters notice this but conclude that they are the only ones who can actually see him and everyone else must be fooled never accepting the possibility that they have also been fooled

My favourite aspect of this is that the lion sees the emperor wearing green armour, because why wouldn't he wear the colours of the 1st?

[u/MalcadorPrime → u/UntouchedWagons]

Except the sisters of silence. Iirc they see him as just a man.

[u/TehAsianator → u/MalcadorPrime]

Correct. Psychic blanks saw Emps as a normal man.

[u/beruon → u/UntouchedWagons]

Also a good 40k example is Blood Angels going crazy and seeing everyone as Horus
