DAY 2: Favourite Dark Type

Monozu /Deino Dark types are cool...but they aren't my favourite type per se. I love the Monozu line though! My best friend and I have this theory where Dienos manifest an alter ego when they mature and have faced hardship. It starts out like the voice at the back of your head that thinks the opposite of you and grows stronger and seems to gain sentience. Upon evolution, the alter ego has manifested into an actual head. During that stage, the Zwellious heads will fight to gain dominance over the other. The stronger personality will end up crossing over into the final stage while the other is subdued (hence the brainless armheads)
