From the anime Shadow Star Narutaru, Hoshimaru is a small weird dragon like creature that one day saves Shiina from drowning. Her life changes instantly with this mysterious little encounter because Hoshimaru turns out to be very powerful.
Why I like him: He doesn't talk or make weird noises. He looks cute too! He almost could be considered a "dangerous Pokemon".
Why I hate him: He's a tricky little bastard!
Overall: Doesn't everyone want a cute little dragon like guy that they can parade around like a backpack with crazy powers?
