Dr Jekyll, previously Jekyll and Hyde, is a random event NPC that appears and urgently asks the player for help making a potion. If talked to, he requests a cleaned herb of the player. If the player has a herb in their inventory, he will take it and give them a potion, but if the player has no herbs he will give the player a Strength potion(2) before disappearing. If the player has multiple herbs, Dr Jekyll will request the highest level herb.

Dr Jekyll is one of three events which will follow players into banks and will not despawn at banks, alongside Count Check and the Genie.

Mr Hyde

Before the Optional Randoms & Goblins update, if ignored, Dr Jekyll would turn into Mr Hyde (level 14–159, depending on the player's Combat level) and attack the player with Melee. If killed, he would drop a potion or an empty vial. Killing him could sometimes be more profitable than giving him a herb, as he could possibly drop a Super restore potion(4).

Trivia

• Dr Jekyll is a direct reference to the mystery novel Strange Case of Dr Jekyll and Mr Hyde by Robert Louis Stevenson. It is about a doctor who created a potion which transformed him into a manifestation of his repressed, evil side, whom he called Mr Hyde. This transformation allowed him to go out at night and do whatever he wanted without tarnishing his personal reputation as Dr Jekyll.
• If a player receives this random event underwater, Jekyll will be seen wearing diving gear.
