How to unlock the Killer Croc achievement in Injustice 2 - Definitive Guide
You will want to select either "Swamp Thing" or "Cyborg" due to weaker characters will be to weak to pick the crocodile up. Weaken your enemy until they are about to be defeated then bring them over to the hanging crocodile and if you defeat them with the intractable object, you will unlock "Killer Croc".
Here is a video guide incase you prefer them over written ones.
Set up a Versus or Single Fight on Very Easy, pick one of the aforementioned characters and any opponent, then chip away their health until it is very low. Then, a little to the left of the arena, you should see a crocodile hanging on a couple of ropes. Make sure the button pops up near your health meter, then simply press to swing the croc and, if connected, finish your opponent off. If it is used before you can finish them, you will need to restart the match and keep your opponent away from them. Maybe pick a smaller foe, such as Robin, so they can't ruin your chance.
Select any mode you like, select any character to play with. Select Slaughter Swamp map and start the match.
Once the match starts keep hitting your rival until he has around 5% of health left on his red bar. At this point go to the left of the screen and you will see a big crocodile hanging on the tree, keep moving until you see the label in the top of the screen and press it, you will send the crocodile to your rival and, if he is defeated with this hit, the match will end showing the trophy in the screen.
