I think Pinsir could fill the grappler niche nicely, bit in a nicely gimmicky way.
I see Pinsir as something of a hybrid between something like Zangeif, and Wario from Super Smash Brothers. Pinsir has a bunch of odd, erratic moves, several of which hurl it in strange directions, and many others which have odd timing. Pinsir's goal is to get in close enough to start grapple-chaining, which is where Pinsir shines.
Pinsir is basically a glorified game of Rock-Paper-Scissors. It lurches around the field, or spits out debuffs, and you have to guess where it is going. Guess right, and you get to act accordingly. Get it wrong, and you get closer to grapple-town.
Once Pinsir grapples you, You have to guess which grapple it is going to follow up with. Get it right, and Pinsir is open to counter attack. Get it wrong, and the pain continues. Get several such predictions wrong in a row, and Pinsir gets a neat finishing slam which does buckets.
Pinsir is at its best against low HP pokemon, since they get fewer mistakes. Pinsir is at his worst against high HP pokemon, since they get more chances.
Pinsir is also great against opponents that rely on prediction, since Pinsir's entire game plan is to get into your brain, and to pinball around until it gets you in those horns.
Burst is Mega-Pinsir, who gets even faster and more erratic movements, as well as a nice ariel grapple chain.
Burst attack is "Guillotine...?", which has Pinsir dive right at that tender neck, only to miss. The enemy pokemon takes damage right to the ticker from the scare.
