I borrowed the idea from this post that Zeda did, because I thought it was cool.
Mako’s horns are really thin a delicate, so he can feel everything they touch. When he gets older they’ll get stronger but right now they’re very much like brittle coral and having them touched isn’t very pleasant.
Ophion’s horns are still extremely sensitive because his kismesis broke them off and then filed them down into the flat state that they’re currently in. It’s very nearly painful whenever anything touches the part that was filed down as they were cut down into the wick, and are therefore growing back extremely slowly. Because of this, in cold weather they have the potential to bleed or crack if he’s not careful to keep them warm enough.
Zikaia has really thick sturdy horns and has pretty much no sensation in them except for close to his skull. If he were taller he’d probably hit them on door frames a lot.
Iasone’s horns are fairly sturdy, but they’re also sensitive. He doesn’t mind them being touched though, as long as they don’t get yanked on.
Areion’s horns have little sensitivity, though he can feel if the barbs on the end touches against anything.
Spathi’s horns function similarly to Areion’s, though as he’s younger and they’re quite a bit smaller they’re a bit more sensitive.
Saenah looses sensation the farther his horns grow out from his skull.
Gesper’s horns are sensitive close to his skull and before they hook backwards. It’s almost a wonder the crook on either/both of his horns hasn’t been broken off before because he has the potential to catch them on things quite a lot without realizing it.
I like that Mako and Obie are ‘no don’t touch those’ buddies. Also Zikaia’s are best for handlebars.
