Yup, thinking it was his ace. Would explain why it's so aggressive (belonged to a trainer who turned insane), why it's overleveled (Savage trying so many times to beat Shade) and why Savage struggled against Shade in the first place (his ace was weak to Shade's).

Or it could be MAGIC and this bear is Savage himself somehow. Stranger things happened in this game (cough Terra cough)

but what if Terra is the only sane person?

... I wasn't prepared for that. My world crumbles around me. 

Was everything a lie? Is Terra the guide we deserve, but not the one we need?

My thanks, o herald or the rainbow-haired prophetess. The reality of Reborn shifts according to a new paradigm in front of my very eyes.

Hail Hydra Terra!
