How to get Fist in Devil Beater

Getting fist is quite a challenge. He is in the same stage as corrupted (?) Shuu, who deals a ton of damage.

On the left wall, when you spawn, look all along the edge on the floor. There should be a semi transparent orange pumpkin. Basically, you stand on this pumpkin with MUTO, and as soon as the boss dies, reset. You should then respawn with fist in your character selection.

Required Character - Fist

Stage - 43 Fight with Hans and Nieve

How to get king in Devil Beater.

In this stage you fight 2 characters - Hans and Nieve

In order to get access to king, there is a secret wall near the other end of the stage where you spawn. It is on a high ledge that you cannot normally jump up to, so you will need to jump on someone / use a character with a high jump (Cielo) to reach it. Just walk up to all the walls and you will find a secret room.

In the room, is a doge with a sword sticking from him. Touch this sword as fist and you will get king. Because you need fist to get king, you will probably need help getting up the ledge where the secret room is (however, I have occasionally glitched up there with one of fist's skills, but its probably easier to get help).

As far as I know, even though the sword disappears, multiple people can get king in one round.
The main challenge of getting king is due to the fact that the stage to get fist is right after (meaning you have to start the entire thing all over again or join a new server)
