Gilbird

I'm having so much fun doing these x3
Gilbird's human outfit has less ornaments.. I dunno. The only reason why he has such strange sleeves is because he is, like pierre, a bird. Only bird type hetalian 'pets' will have that.

Besides the humanic form, he can also transform into a chocobo (actually it's far larger than also), so Prussia can ride him xD
There's been pictures on that too.
And then he can become the prussian eagle of course! It's like.. digivolving or something xD"
