How to unlock the The Grappler achievement in Mortal Kombat - Definitive Guide
Just perform these using every characters in Arcade Ladder.
The best way to get this is to set arcade ladder to beginner, one round. Go for it the same time as "fatalities with every character", "x-rays with every character" and "complete arcade ladder with every character" to save time - 4 achievements will pop when you are on your last runthrough.
Complete story mode first though to unlock Quan-chi and Cyber Sub-Zero.
The fastest way to go through everyone is load up Versus Two-On-Two (Tag), select 2 characters you need to complete on controller 1, and whoever on controller 2.
At the loading screen, on controller 2 only, if you press X twice and Y twice it will make player 2 start at Quarter Health.
In the match, do your neutral/back throw, and your forward throw, punch once (this will kill Player 2's first character), tag out, do your 2nd character's throws, and then finish player 2's 2nd character. Rinse and repeat till you have the achievement.
R1 + forward = forward throw.
You need to do this for the fighters in the vanilla version of MK as well as the two characters unlocked by completing story mode. (Cyber Sub-Zero and Quan Chi.)
Training mode does not seem a viable option for unlocking this trophy, so you'll need to do this vs the CPU, people online or a second player.
This is another one that will come naturally if you perform throws with every character whilst going for the "Arcade Champion" trophy. While playing through the ladder, perform both the forward throw (Forward + L Button) and backward throw (L Button) when next to the opponent. The trophy will unlock once you have performed both throws for all 32 characters.
To perform a throw you must be next to your opponent and then hit plus the direction you want to throw the opponent. Press + to throw forward and or + to throw backward.
This can not be done in Training and you must also do the throws of hidden characters Quan Chi and Cyber Sub-Zero.
For this one you need to keep track of every fighter and perform a throw forward and backward, by pressing and moving the left or right for the throws. There are 28 available fighters so you will need to finish the story mode to unlock the 2 remaining characters (Cyber Sub-Zero and Quan Chi). You can download this CHECKLIST to help keep track of the moves and fighters.

So here's the path: Training -> Tag Team Practice.
Choose two heroes (I did it in order, 4 heroes in a line => two runs).
Perform 2 different grabs for one character, then R and two grabs for the other. Leave and so on until you get the trophy.
