Fyodor Gryaznov/Tropes

A-G
Always Smiling:  Fyodor seems to always be smiling, even when he might be angry or annoyed at someone.

A Really Big Fish Story: Fyodor tends to ramble on about experiences he's had at various times, whether the people around him want to hear it or not.

Big Brother: In Sabertooth or even in his old team Fyodor typically took the role of big brother, since he was one of  the oldest in both factions.

Creepy Threats: Sometimes when one of his teammates gets on his nerves Fyodor will threaten them harshly, while keeping a grin on his face the whole time.

Card Shark: Fyodor likes playing Poker, Go-Fish, and other kinds of card games, and is actually quite good.

Guild Whore: Fyodor was origonally a member of Fairy Tail, then a member of Raven Tail, then he went back to FT, and now he's a member of Sabertooth, so Fyodor is essentially a "guild whore."

H-P
Little Bro: Fyodor has always been seen by most of the mages of Fairy Tail as a sort of little brother. Even after the time-skip he was usually looked down on, despite being older and stronger than some members. Noble Roots: Fyodor's father is the heir to the noble family, The House of Nidas, a very wealthy family that manages the relations between the countries of Fiore and Seven, meaning Fyodor is a future ambassador.

Q-V
Respect Your Elders: Most of Fyodor's older relatives are very powerful and famous wizards, such as his paternal grandfather, who's the Head of an entire family of mages, his mother and her sisters, who all instill fear into the hearts of those who know them, and not to mention his maternal grandmother is a FREAKING PHOENIX!

Unknown Origins: For some reason, Fyodor was born with green hair, which is strange since both his parents have brown hair. No one knows where that gene came.
