Demonic gorillas are powerful creatures found in the Crash Site Cavern. Two of them are fought during Monkey Madness II, in the penultimate stage of the fight. After the quest is completed, more demonic gorillas can be found in the caverns alongside their tortured brethren. They are primarily killed for their zenyte shard and ballista component drops.
Demonic gorillas use all three combat styles to attack. They will change combat styles after missing three hits in that attack style. They are also capable of using protection prayers, and will switch to protect from the player's attack style after taking 50 damage from it. Therefore, players must bring at least two different combat styles to kill them. As they have very high magical defence, they are most often killed with melee and ranged.
The gorillas also have a special attack where they send a rock crashing down at the player's position, which can be easily avoided by moving one tile away from the current spot when the attack was initiated. If struck by this rock, the player will take 33% of their current health as damage; it cannot kill the player by itself as a result.
Demonic gorillas count as monkeys and black demons for the progression of Slayer tasks. As they are demons, they are susceptible to the effects of demonbane weapons, excluding holy water. Demonic gorillas cannot be damaged with a Dwarf multicannon.
Players can check the kill count by reading Nieve's gravestone next to Lumo at the opening in the fence.
Note: The prayers of the demonic gorilla cannot be bypassed through the use of Verac's set or special attacks.
Drop rates estimated based on 14,768,867 kills from the Drop Rate Project, unless otherwise cited.
The average demonic gorilla kill is worth 53,223, including the zenyte shard drop. Without zenyte shards, the average kill would only be worth 20,940.

- Demonic gorillas are similar to the tormented demons of RuneScape 3; both use all three forms of combat, protection prayers and drop items that are used to create more powerful equipment.
- Demonic gorillas' prayers were slightly changed several days after release due to several glitches happening with specific weapons, notably the Saradomin godsword.
