"A person is never more honest than when they think they're alone."
— Goyo

César Ruiz Hernández, codenamed Goyo, is a Defending Operator featured in Tom Clancy's Rainbow Six Siege. He was introduced in the Operation Ember Rise expansion alongside Amaru.[1]

Goyo's gadget was reworked in the Demon Veil expansion.


César Ruiz Hernández was eleven years old when a bomb destroyed his home, killing his father and sister and severely injuring his mother. With the help of Specialist Azucena Rocío "Amaru" Quispe, César's mother Sofia taught him to observe his surroundings, and to avoid the other boys his age who had been drawn into gang-related affairs. She encouraged him to enroll at the Heroic Naval Military School, where he graduated as a teniente de corbeta (lieutenant). He joined the Naval Infantry, then the Amphibious Commando Battalion, participating extensively in anti-smuggling operations and several high-profile arrests. Becoming a member of the Fuerzas Especiales introduced him to the reality that drugs were no longer the primary source of income for the cartels. He began working with UNESCO and INTERPOL to combat antiquities trafficking, where he gained the attention of Rainbow as a mind with a keen tactical sense and exceptional forward-thinking.

Hernández and Amaru were later recruited into Rainbow in 2019. In early 2021, he and Miles "Castle" Campbell were sent to Los Angeles by Eliza "Ash" Cohen to recruit Santiago "Flores" Lucero into Rainbow. After discussing a bit of Flores' trade, they asked if Flores had heard of Rainbow and The Program. Flores then realized who had sent them and accepted their offer to join Rainbow. As a test, Hernández, Ash, and Castle observed Lucero perform one last heist on the home of a crime boss in Los Angeles.

Psychological Report[]

Specialist César "Goyo" Ruiz Hernández is a rare find. His jacket reads like any normal military trajectory, until you notice the devil behind the details. To confirm my theory, during our first meeting I challenged him to a game of chess. I won't mention how few moves it took him to beat me. César himself seemed to think nothing of it.

This humble attitude is at the heart of his character. His mother, Sofia - who protected him from the brunt of the bomb's blast - has cultivated an overtly optimistic worldview. Growing up where he did, when he did, she also instilled in him a cat-and-mouse mindset, to keep him clear of the negative influences that would have been especially tempting to a young fatherless boy with too much time on his hands. She was helped in this by Specialist Azucena Rocío "Amaru" Quispe, whose intermittent presence and strong familial values shored up a gap that Sofia alone couldn't fill. [...] It's clear to me that Quispe, with her inherent attachment to her country and her family history, provided a stabilizing influence during Hernández's undoubtedly troubled adolescence.

Hernández is the kind to think carefully before speaking, a trait which can lead people to underestimate him. He is neither churlish nor aloof, but constantly considering the many angles of the problem set before him. [...] His ability to track and guide his quarry, from determining their route to understanding how they will react to threats, is uncanny. In a prosaic example, he brought Specialist Tina Lin "Frost" Tsang a bottle of apple-flavored soda on the first day of Fall, despite them only having met once before. She was unperturbed, but I could see that Hernández had braced himself for a far less positive outcome.

Specialist Hernández has otherwise become a staple of our briefings, his incisive questions highlighting new tactical considerations or encouraging out-of-the-box thinking from the other members of the team. I must admit, it's refreshing to see what changes a new perspective and an impeccable poker face can bring to an otherwise very self-assured group of individuals.

Gameplay Description[]

Unique Gadget
Volcán Shield.png

Volcán Canister x 4
"Incendiary bomb that can be deployed on floors or walls and explodes when destroyed."
— In-game description

A Medium Health Operator, Goyo's unique gadget is the Volcán Canister. The canister explodes when fired upon, leaving a large carpet of flames as an area of denial for players who try to cross it.

  • Goyo has four Volcán Canisters. He can deploy them on all reachable surfaces including walls, floors, hatches, as well as several types of furniture.
  • Canisters take approximately 4 seconds to deploy.
  • Canisters cannot be placed on Deployable Shields.
  • The Volcán Canister will detonate if its red explosive canister is hit by gunfire, explosives, or melee attacks. The rest of the canister is bulletproof but is still susceptible to explosives.
  • If Canister's are placed close enough together and one detonates, a chain reaction will occur and detonate all Canisters within the firsts area of effect.
  • The fire deals 12 points of damage per tick and inflicts three ticks of damage per second (36 DPS). It lasts 20 seconds before dissipating. Neither the explosion nor the fire damage any gadgets, friendly or not.
  • When detonated, the canister creates a small explosive which will make a small hole if planted on a soft wall. It will not deal explosive damage or destroy friendly gadgets.
  • A large area of flames will spread on the side of the wall the canister was planted on while a smaller area of flames will spread through the hole on the other side of the wall. This allows for area denial in multiple rooms with a single canister.
  • The Canister can be placed on Barricades. It will detonate if the barricade is destroyed.
  • If the Canister is placed on a window barricade above the window sill, its fire will spread on both sides of the window.
  • If the Canister is placed below the window sill on a window barricade, it will be almost impossible for Attackers to see it. This can prove to be effective against Attackers who vault through window barricades.
  • If placed on floor hatches, detonation will destroy the hatch and cause fire to spread to the floor below. The fire will only spread
  • Volcan Canisters can be placed to block Drone holes.
  • Twitch's Shock Drones cannot trigger the explosives.


  • Kapkan's Entry Denial Devices can be used to automatically provide an explosion that triggers the Canister.
  • If an Evil Eye is set behind a Volcán Shield, Maestro can use them to detonate the Shield from a safe distance, without needing to expose himself.
  • The Volcan Canister can be placed on Castle's Armor Panels and will detonate if breached.
  • Melusi's Banshees can slow down Attackers caught in the flames.
  • The Canister is immune to electricity, allowing Bandit's Shock Wires or Kaid's Electroclaws to electrify it without accidentally detonating it.


  • A poorly placed Volcán Canister can easily be used against the Defenders.
  • Ash's Breaching Rounds, Sledge's Hammer and Zofia's Impact Grenades will trigger the explosion with their gadgets.
  • Zero's Argus Camera lasers can trigger explosions if the canister is hit directly.
  • Amaru can bypass a detonated canister when using her gaget to enter a window. She will land at the edge of the Canister's flames and will not take damage if she moves quick enough.
  • Maverick's blowtorch can trigger the explosion by hitting the canister once.
  • The gadget is vulnerable to attacks through the floor from above or below.

Device Evaluation[]

Mira, I got to admit I was surprised when you asked me to look over Specialist César "Goyo" Ruiz Hernández's prototype. For someone with a limited knowledge of chemical interactions, he's sure knocked together a bunch of things that will make a loud bang, while causing minimal damage. I'd compare it to a flash-and-dazzle firework, but with more personality.

He's used the time-honored mix of kerosene and potassium chlorate as his base, so I had no real improvements to suggest on that front. What I did do was give him the formula for my home brew - a cocktail to trigger a gas explosion using a specific blend of cyanogen, hydrogen, and some other fun stuff. The magnesium casing generates enough heat on impact to ignite the acetylene derivative swirling around the inside and blow the whole thing sky-high. Like I said, impressive without bringing the hypothetical building down around your ears.

Hernández had already added a light flame retardant to the mix, but balked at the idea of carrying an actual fire extinguisher. He did mutter something about an "anti-fire grenade" as we walked way, though.

Sorry in advance.

White Masks Reloading


  • Volcán is Spanish for volcano.
  • Goyo's codename is based on a nickname for the Mexican Popocatépetl volcano, "Don Goyo".
  • Goyo, along with Amaru, were teased during Operation Phantom Sight in Nøkk's Concept Art 5 on the Rainbow Six Siege official site. The background of the concept art shows a blackboard with sketches of a jerry can and a grapple gun, corresponding to Goyo and Amaru's gadgets.
  • Goyo and Castle were both sent by Ash to recruit Flores, as shown in the Crimson Heist Story Trailer.
  • Prior to his rework in the Demon Veil expansion, Goyo was equipped with Volcán Shields. While appearing like a Deployable Shield from the front, it concealed the explosive canister on the back. It functioned in a similar manner as the Volcán Canister with several notable differences.
  • Goyo had three Volcán Shields which was later reduced to two. He could deploy them at a slightly faster rate than a normal Deployable Shield.
  • At close ranges, the explosion from the Shield detonating dealt 40 damage to a Light Armored Operator, 34 damage to a Medium Armored Operator, and 30 damage to a Heavy Armored Operator.
  • If an Evil Eye was set behind a Volcán Shield, Maestro could use them to detonate the Shield from a safe distance, without needing to expose himself.
  • The gadget was vulnerable to attacks through the floor from above or below.
  • Hostages that were damaged by the explosion of the shield or resulting flames were considered to be damaged as well as possibly killed by Goyo even if the shield was detonated by an attacker. Therefore it was possible for an attacker to escort the hostage next to a shield and shoot the explosive, resulting in a loss for the Defenders due to Goyo being credited for the kill. Since update 4.3.2 this was no longer true, as the damage was changed to attribute whoever detonated the shield rather than Goyo himself.
