head canon for Saix/isa the whole moon effecting him I think he has had to deal with all his life. the lack of heart simply makes him more feral
I hope the result won’t disappoint you, but I don’t think it was that strong
Isa / Saïx :
• The body is made by approximately 75% of water
• And strangely, some people are more sensible about it than other
• Isa was one of these people
• Around a full moon, Isa was sleeping less and waking up a lot more in the night than usual
• When he was a Nobody though, he was already not sleeping much anyway
• During the full moon, the libido of Isa, and way more when he was Saïx, was at its paroxysm
• But at the last phase of the moon, it was the total opposite ; there was no sexual urge anymore, nothing
• Axel was certainly the only one to know, but when the moon was in its croissant phase, Saïx was using a care’s mask on his hair since because of the moon, his hair was in a regenerative phase
• When they were younger Lea learned fast that Isa was… more irritable when the full moon was there. It was probably the only days when Lea could see Isa furious
• No need to explain that it was way worst when he was a Nobody. He needed time to control his Berserk though at The World That Never Was because of Kingdom Hearts
• It was never intended, but on the last quarter of the moon, Isa ─and so Saïx─ was many times thinking about what he did, what he said and maybe “apologizes” to Lea ─or Axel─ if he needed to
• When he was younger, he wasn’t taking all the superstition seriously
• But when the Darkness gave him powers, he couldn’t say that moon didn’t have an impact on him anymore
• And he began to read all information he could and working around these “superstitions”
