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, you must bring at least two different combat styles to kill them. As they have very high magical defences, they are most often killed with melee and range.
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 out of the way. If you are hit by this attack, it will deal 1/3 of the player's current HP (meaning that it alone cannot kill you) allowing it to hit over 30 damage on players with high HP.
Most of the gorillas reside in a multi-way combat area, making it very dangerous if the player is attacked by more than one at a time. However, there is a single-way area where more demonic gorillas can be fought safely. However, if the player accidentally safespots the gorilla while it is trying to use a melee attack, it is possible for nearby demonic gorillas to attack the player if they are not tolerant yet.
Demonic gorillas count as monkeys and black demons during a Slayer assignment. As they are demons, they are susceptible to the effects of demonbane weapons. Demonic gorillas cannot be damaged with a Dwarf multicannon.
You can check the kill count by reading the 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 276,492 kills from the Old School RuneScape Wiki drop log project, unless otherwise cited.
The average demonic gorilla kill is worth 54,846, including the zenyte shard drop. Without zenyte shards, the average kill would only be worth 22,749.

- 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.
