I'm terribly sorry, but you're out of luck. But we do have a different sort of companion for you -- the kind that interjects with silly catchphrases while he's merrily pulling half the hostile wildlife to your side. The kind that stares down the face of danger without fear, only the empty eyes of one who has taken one too many blows to the head, tongue dangling wildly from the corner of his mouth as a gobbet of drool lazily grazes his cheek.
His name is Martar. He's not-so-smart. But he'll tag along with you if you know where to find him.
Martar the Not-So-Smart isn't a quest objective, nor is he classified as a rare mob. He's a level 86 elite that makes a circle just north of the Arboretum in the Jade Forest. In the screenshot above, he's at coordinates 55,30, directly north of the Arboretum, but he circles the entire glade, so you may have to search for him. However, it's not like Pandaria is crawling with gnolls, so he's pretty easy to spot.
And because he's not-so-smart, he's also not-so-hard to fight at all. All Martar does in the way of attacks is stand in front of you and shoot you with his gun. It might tickle a little if you're a fresh level 85, but it's nothing to be overly concerned with. After killing him, Martar has a chance to drop Martar's Magnifying Glass, a level 85 trinket that will summon Martar to your side for 10 minutes, during which you can adventure or frolic to your heart's content. And even if you don't get the magnifying glass, you'll score one of six Steamy Romance Novels, so at least you'll have some reading material for your troubles.
Martar is not an instant respawn, so you may not find him immediately, but he's a fairly common sight in the Jade Forest, so you don't have to worry about camping his spawn point for days on end. Be warned, however -- summoning Martar means that he will gleefully shoot any hostile mob that happens to be nearby, whether you'd like him to or not. After all, he's not especially bright.
