From Melvor Idle

Prat is known to be the second developer of Melvor Idle. He comes up with ideas of weapon and new concepts, both Prat and Malcs (aka MrFrux) balance and “number crunch” it, and Malcs codes it into a new update.

Some things in the game named after him are Cape of Prat and Prat, the Protector of Secrets.

His role in the Discord server is “Level 98 (Unnecessary)”.

His profile picture in Discord may mean that he likes penguins. When asked what his profile picture was, he once replied “It’s a person riding a penguin into penguinland to more penguins...”. His profile picture has since changed, and his thoughts are now "I woke up one day and was turned into a penguin, pfp (is) actually my drivers license". How thought provoking.

It also says that it was Prat's idea that you had to have 100 Various Dungeon clears to be able to use Ancient Magicks.

Additionally, it is confirmed that Prat is evil, based on the description of the Slayer 2.0 update. It states, “Slayer 2.0, brought to you by Prat. He’s evil, so expect this to be evil.”

Maybe we shall know more about him as time goes on.

The many faces of Prat.
