Look to the left to see a clock with telekinetic arms. Swap to the Invisible Woman and spin it around twice to get the parts for the handle of the door next to it.
Enter the kitchen and twitch the curtain aside with telekinesis to get stuff thrown at you. Destroy the thrown objects to get the parts for the toilet nearby. Pull the chain with telekinesis to get a telekinetic hammer. Use the hammer on the boards next to the toilet, hiding the water heater. Swap to the Human Torch and melt the heater to get Dormammu out of the bath. He will exit once again but this time into the room on the right.
Follow him into the room and with the Invisible Woman's telekinesis put the books away on the left. Swap to the Human Torch and melt open the lid of the chest on the right to get the keys for the piano. The piano will rotate and reveal a switch. Pull on it and Dormammu will be forced to move once again.
Follow him upstairs into the attic. On the left side of the room is a skeleton connected to a cloth. Use telekinesis to pull the skeleton down and show Dr Strange trapped in a mirror. He will inform you that three objects in the room are stopping him from leaving the mirror. Swap to the Human Torch and go around to the moving items and melt the golden crystals inside. After all three are done Dr Strange joins your party.
Now your task is to defeat Dormammu. Head downstairs and confront him. The easiest (if slow) way is to stay inside the Invisible Woman's telekinetic bubble and slowly walk towards him before punching him. This keeps you safe and prevents his instant kill laser attack. After his hearts are depleted the level ends.

Stan Lee – In the kitchen, use super sense to spot the two web spots on the light. Use a web based character to pull it down and swap to a flying character to reach the room above. Use an explosives character to blow open the box in the back of the small room to free Stan.
Character – Invisible Woman (F.F): When you start the bonus level, nearby is a cupboard locked with a silver lego padlock. Blow it apart with an explosives character to get the token.
Red Brick – In the attic (or upper area) on the right wall is a sand spot for a sand based character to enter. Travel through to reach another room with a chest. Use a telekinetic character to open the chest and build the Christmas tree for a present with a web spot. Swap to a web character and open it up to receive the red brick.
