Devil plays very offensively in Head Soccer when he is controlled by the computer. After he has activated his power button for the first time, he will hardly be able to kick again. This could be a mistake. However, while in his power button state, he is able to jump much higher and move faster across the field.
The Devil has two separate appearances. The first one has white/grey hair and looks like a "normal" person. However, he has red eyes, which are almost fully covered by his medium length hair. Also, he has a mysterious smile around his mouth and a thin nose. In other words, he has an ominous facial expression.
His second appearance, the power button appearance, is a bat that has its vampire wings outstretched, enabling him to jump further and move quicker. His head looks the same as in his first appearance, but it's all dark purple, and he gains two horns on both sides of his head and shines a light from his eyes. The Devil's full body is dark purple as well.
The Devil's Power Shot is the Vampire Shot. When his Power Button is activated, he transforms into a bat and as soon as he gets the ball, he will launch the Vampire Shot. When the Devil starts his power up a large, demonic shadow will come from where the Devil is. It will move up and down slightly and if it hits the opposing player it will stuff them in the ground. Behind that shadow is another smaller shadow that contains the ball in its mouth and two larger ones that will also trample the player.
There are ways to play with him, even if you don't consider him worth the money.
The first one works for Survival. Give up a Survival match and then go back. While the "Would you like to continue?" message appears, press Upgrade or Costume, press back and swipe left or right until you have The Devil selected. Then click No, and you will be able to use him.
You can also play with him in Head Cup. Go to Head Cup, press Next in the Player select screen, press Upgrade or Costume, go back and you see that you can move the background. Go to Portugal or Canada in the select screen and watch a video. When the video is over, you have to swipe one right if you have chosen Portugal and one left if you've chosen Canada to select the Devil. But make sure you do this very quickly, because after the video has ended, the Head Cup will start almost immediately.
The last possibility is in Death Mode. While you are asked if you want to spend 5,000 points, click on Upgrade or Costume in the bottom of the screen. Then, press Back, and that's how you can make the background movable again. Thereafter, swipe right or left to select the Devil and click yes. This will allow you to play as Devil, even if you haven't unlocked him!
Note: The play with any character glitch was fixed in the 6.0 Update, so you can´t play with him unless you pay for him.
He is the first character with white hair. Pluto's hair color is most similar from all the later characters to that of the Devil.
The Devil is the second character with red eyes, the first being Cyborg.
He is the first character that changes their appearance when you activate power button.
His power button effect enables him to jump further and move quicker across the field. Switzerland is the only other character that gains higher stats due to his power button effect, but his stat increase is visibly smaller than that of Devil.
He is the first character you have to pay real money for to unlock, the second is Mon-K.
