Spoilers: (Highlight to reveal)
Sweet Tooth wishes to find out where "She" was hiding. He tried to kill "She" (his daughter Sophie) but she stabbed him in the eye with scissors and got away when he first tried killing her. It turns out she killed herself 10 years prior to him winning the tournament and he gets buried alive in his ending. His story shows that the killer in him was a voice that was calling to Marcus Kane and when it eventually got through to him, he sculpted the mask and attacked his family first.

Mr. Grimm wishes that he could go back in time to save his dad's life, but is put in the car with his child self and father as his present day self and get's strangled by his father while his father should be driving. They get into a car accident and Mr. Grimm gets killed by a child version of himself in his ending.

Dollface wants to be a supermodel. She killed and attacked other models (sawing one of the heels of their shoe so it would break and they would fall) to try and make it to the top. She got into a car accident and needed surgery. The doctor who helped her told her that there was a tiny scar on her face from surgery but she thought he was out to get her too so she killed him as well. She finds a doctor who, I shit you not, is a midget. This doctor puts the mask on her and tells her to come back to take it off in 6 days. She goes back in 6 days and he isn't there. She wins the tournament and goes to Calypso and instead of wishing to remove the mask like originally planned, she wishes to be on the runway and shine as the top model. Calypso puts her on a runway with a plane about to land on it. She tried to get away but her heel broke and she fell, thus being killed by the plane. We see Preacher in a white padded room rambling on about how he knows who calypso really is as it zooms out and we see a castle like building which is a painting on a wall in Calypso's actual building (I guess he has people trapped in the painting). A Bit of Credits hit and then we see Charlie Kane (Needles' son) talking, and it is revealed that he is alive. He goes to the grave that Sweet Tooth and Sophie were buried in and digs and removes The Mask from the grave. He puts it on and lights his head on fire vowing to take revenge on Calypso. We then get some more credits, then Preacher rambling again (with a black screen) about how Calypso can raise the dead and then they are forever loyal to him (like he does at the beginning of the game. This is followed by Calypso standing at the grave talking to someone in there. holding a bag. He says he made something especially for the person he is talking to. He then says "Welcome Back" and we see Sophie wearing a clown mask along with Sweet Tooth like attire.
