Amadeus

Amadeus is a mutant berger picard

he is French     

He is very rowdy and a bit of a punk

 He is part of Red Hare and plays guitar

Amadeus is good friends with Rex 

He attacked Night shade as a way to frame Night for Amadeus' murder of the priest from the village which he did just to mess with Benjamin (head of the village). Night shade got scared and chewed part of Amadeus' face off, soon regretted it, then bandaged Amadeus up. They are now good friends and joke about it (????).
