I think alpha wyvern should be improved upon, I want them to be like mini bosses that you can decide to either tame or defeat like the titans. There should be and alpha wyvern for each element, they should be bigger and look different to reflect their status and possibly age like alpha ice wyvern shaving more ice structures on its head and wings. Once they detect you they roar instead of making that weird shriek that sounds like my cat hacking up a hair ball, their breath attacks could be longer and maybe different as well. After defeating them maybe they crash to the ground or just flop over if they already landed and if you act quick enough with either kibble or medicine you tame them… kinda. I think they should be like a giga where if they sustain too much damage they go berserk and the only way to make them stop is to defeat them again and re/tame them basically
