You can save it for something else cause a bunch of character have resistances to fear manipulation for like no reason
Resistance -
Adam: (
Stood his ground against the menacing aura exerted by the Adamas form of Zeus), Adamas mode was so scary that it forced Adam to put up his guard for the first time in the fight meaning that it did effect him in some way.
Zeus: (
Unaffected by the menacing aura exerted by Odin at his side), Zeus is most likely in the same league as Odin, if not higher. Bro has no reason to be afraid of him. Odin's ability has no evidence that it causes fear in anyways other than people ******** themselves at how strong he is
Heracles: (
Jack The Ripper failed to induce to fear into him, and his color remained the same), he's just brave. Jack scares people by violently killing them, Heracles faced death head on.
Buddha:
(Was unfazed by Zeus and Odin's presence), once again no evidence that Odin actively causes people to fear him in any other way besides being powerful. Buddha is really cocky and is even willing to fight him with his barehands. He also looked pretty scared when Pāpīyas first emerged
Qin Shi Huang: (
Was the only one capable of standing against the Demon God Chiyou without fear), just him being brave
Hades: (
Regarded as completely unwavering in the face of danger), are you ******* kidding me right now
Beelzebub: (
Was unphased by Odin’s menacing aura), as mentioned before he's suicidal and can fight Odin, he's got no reason to be afraid
Lü Bu: (
Fight smoothly against Dong Zhou, who with just a few words scared Wang Yun causing him to age prematurely to death), maybe
Has Fear manipulation
Thor -
(Able to strike fear into Göll and Brunhilde with his aura alone), I to would be scared shitless if a real strong dude killed someone in front of me.
Buddha - (
Induced fear into Hajun, when the later previously didn't display any emotions), maybe but I feel like Pāpīyas was scared because Buddha was able to remain hopeful and never wavered once despite how powerful Pāpīyas is.
Additionally, Beelzebub has Probability Manipulation (
Said to bring misfortune to those who try to get close to him), not only is this ever shown but its also most likely referring to the fact that he kills people when he feels love for them.
