An idea suggested by GlitztheMimiga on DA, what if the Snorlax Eva from her dream was an Alternate Universe counterpart?

This version of Eva does not have a bag leg, instead her disability is hypersomnia (repeatedly falls asleep through the day, usually lasting an hour or two) and is almost impossible to awaken until she wakes up on her own.

She evolved into a Snorlax at a much younger age than normal because she's such a joyful and happy girl and she most certainly still has the appetite of a full Snorlax.
