Here is a test is based on Carl Jung’s and Isabel Briggs Myers’ typological approach to personality.
Here is an Enneagram personality test.
You can take them in character, or look up the different types and then assign the one that you think fits your character best.
I’ve done this for all of our OCs once. Anyway for the pointless fun of it, my guesses for these guys:
Eames: ENFP and 3w4
Arthur: ISTJ and 5w6
Thor: ESFP and 8w7
Loki: ISFJ and 1w9
Bane: ISTJ and 8w9
I am INFJ and 3w4, what are you?
