My friend who got to play the 90 minute game play demo told me about this pokemon. Tho for obvious reasons I can't say who this friend is.

He told me of this Hypogriff like pokemon. That evolves at level 20 into a flying/fire type. However its first stage is just a flying type.

He wouldn't give me more details other than what its first stage looks like. He described it to me and I drew this. He took a look and said it is very similar. However he wouldn't tell me what future evolutions looked like incase he gets traced as the only one who evolved one.
