King Deviltchi has gray skin and wears a dark blue mask with devil horns. His body is dark blue and has claws and stick legs, and large devil wings on his back.
When King Deviltchi the First retired, he turned the throne over to his son, the young King Deviltchi the Second, despite the younger Deviltchi's lack of confidence in being King of Devil World. Even though he has a proper place to live at Devil Castle, he often spends nights alone in the lighthouse on Gaikotsu Cape, watching the stars. Even though he strong magical powers, he only feels emptiness about his abilities.

Debirutch no Tamagotch
King Deviltchi evolves from Bird Deviltchi. The user must keep the meters empty and DP over 80. After six days, the Devil will have a naughty episode; if the player does not scold it, it will become King Deviltchi.
- King Deviltchi has a unique animation where it turns into a bat and flies around the screen. This happens at midnight, when it goes to sleep.
- As a result of this, King Deviltchi is tied with Bird Deviltchi for having the latest sleep time.
- It appears to be heavily inspired by one of the antagonists of Tamagotchi's sister series, Devimon of Digimon. The two characters have nearly identical sprites and Devimon debuted the year before the Debirutch no Tamagotch was released. The opposite happened with Digimon's Nanimon, who was based on Oyajitchi.
