My MLP OC #1

This is Rory, the first OC that came in my mind and before you ask, yes, he is a wolf.  One who co-owns the Anomaly Research Center near Ponyville in the yet-unsurfaced pony fanfic Equestria Primeval.  The vector belongs to Kaylink:  kaylink.deviantart.com/

Let's go basic here and observe his relationships with the main ponies:

Twilight Sparkle
Sometimes the relationship is that he is her connection to the outside world, though it might not be as obvious as the Watson/Sherlock relationship.  He sometimes also serves as her personal tutor, teaching her the advanced magic that, were it not for him, may be lost in Equestria forever.

Fluttershy
Out of all the Mane Six, Fluttershy is closest to him, probably because of her love for animals.  He even manages to live in her cottage.  Because of this close friendship, he cares and worries for her more than any other pony.  His relationship with Angel Bunny started out as benevolent, but after freeing him from the shining wire without a shred of thanks, any mention or sight of the rabbit gives him a spite strong enough to overrun his predatory instincts.

Rainbow Dash
He tolerates her, up to a point.  Generally, he could care less about what happens to her, but there were moments when he really misses her.  The most notable of which is where Rainbow Dash suffers an accident and has holed herself up for too long.  This annoys him to the extent of creating the Mysterious Mare-Do-Well.

Rarity
He simply does not understand her meticulous desire for fashion.  Regardless, he manages to find a way to help before she reaches drama-queen levels.

Pinkie Pie
His relationship with Pinkie Pie is a mixed bag.  When she makes a smart remark, she amazes him.  When she acts oblivious or without thinking, this annoys him humongously.  He is particularly annoyed by her wanting to brighten his day when he insists that he can do it by himself.

Applejack
His least favorite pony.  Her headstrong attitude always clashes with his good intentions on the grounds that he is a wolf, and wolves threaten livestock.  This results in him assing her off, but there are moments that earned her to trust him for a change.

The Cutie Mark Crusaders
At first, their childish antics annoy him.  But upon observing their determination, their drive, he decides to hang around with them whenever.  He becomes their alpha male, and their antics bring out his fun side.  Also included in his pack are Dinky Hooves, Pipsqueak, Button Mash and, to an extent, Babs Seed.  Diamond Tiara he has a tactless hatred against for not respecting any elders, and Silver Spoon he sees potential, but remains cautious.
