Tom Clancy's Rainbow Six Siege - Echo Operator

Tom Clancy's Rainbow Six Siege - Echo Operator

Masaru "Echo" Enatsu (Japanese: 江夏 優[1], Enatsu Masaru) is a Defending Operator featured in Tom Clancy's Rainbow Six Siege, introduced in the Operation Red Crow expansion alongside Hibana. A Heavy Armored Operator, Echo's unique gadget is a hovering drone known as Yokai, which can stick to flat surfaces on a ceiling and cloak, as well as emit ultrasonic bursts that can disorient the enemy.[2]


Masaru Enatsu grew up in Suginami City, Tokyo. This heavily populated city center is home to several animation studios and technology companies. At 16 years old, Enatsu was already challenging the robotics field by creating autonomous flying robots capable of search-and-rescue missions in highly difficult conditions. Two years later, he won the International Aerial Robotics Competition (IARC) and is known as having pushed the limits of what flying robots could accomplish.

Enatsu was noticed by the National Police Security Bureau during his studies in Science and Engineering at the Tokyo Metropolitan University. Enticed to test his devices on the field, he entered the National Police Academy. A year later, he joined the Tokyo Metropolitan, Police Department Special Unit.

Efficiency-obsessed and blunt, Enatsu is a talented officer despite his apathetic nature. In the wake of Nagoya's hostage crisis in 2007, Enatsu decided to transfer to the Aichi Prefectural Police Department Special Unit.[3]

Psychological Profile

Singularly focused, Enatsu's blunt communication style divides group harmony. His tendency to dismiss feedback has kept him from advancing to a higher rank.[4]

Gameplay Description

Echo himself is suited for holding down the objective. Yokai, on the other hand, does most of his work for him. It is used to remotely survey his hold and disrupt Attackers from above. Able to stick to ceilings and turn invisible, Yokai can also disorient Attackers with its ultrasonic blasts.

  • Much like Attacker drones, Echo throws the Yokai when deploying it, which can allow it to reach normally unreachable areas.
  • While unable to jump like normal Drones, Yokai has the ability to launch itself upwards. If Yokai comes into contact with a flat ceiling, it will attach and secure itself, as well as activating its second set of abilities.
  • Yokai has a 2-second cooldown between jumps, akin to normal Drones.
  • Yokai's jump is limited vertically to 5 meters. This is apparent in rooms that exceed this limit in certain areas such as the Lobby of Bank.
  • The cloaking mechanism renders Yokai invisible, but there is a slight rippling effect to it. The cloak will also deactivate temporarily when it uses an ultrasonic blast.
  • If Yokai does hit an uneven ceiling, it will shake for about a second before falling back down to the ground.
  • When attached to the ceiling, Yokai will have access to his ultrasonic blasts, disorientating anyone caught in its wake, including other Defenders.
  • The blast only needs to hit an Operator directly to disorientate them.
  • Disorientation causes vision to be blurred a bit, with a shaking afterimage, darkened peripherals, and scattered dots of light, while also temporarily muddling their audio.
  • It takes around 10 seconds for affected Operators to recover from the effect. However, moving will lengthen the recovery time to up to twice its normal duration, on top of making the disorientation effects more severe such as darker peripherals and a more uncontrollable-but-steady screen sway.
  • Yokai can only have up to three ultrasonic charges in reserve. However, it can recharge these charges every 20 seconds.
  • The blasts' effective range is 14 meters. Although the blast looks like it has travel time, it is actually instantaneous when it hits anyone.
  • The ultrasonic blast cancels most actions that its targets are performing when hit, such as Thermite deploying an Exothermic Charge or an Attacker planting a defuser in Bomb. A Montagne extending his shield will retract his shield if he is blasted. One notable action that it cannot cancel is pulling the needle from Lesion's Gu mines.
  • The ultrasonic blast also cancels Finka's Adrenal Surge if it was activated. However, another one activated afterwards will override it.
  • The camera on Yokai is exclusive to Echo. It is also unable to scan enemies.
  • Yokai's camera also has a limit to how much is can see. When on the ground, it can only see up to 40 degrees upwards. When attached to a ceiling, it has more freedom in surveillance as it can see everything below its level.
  • Even when dead, Echo can still see through Yokai's camera feed when in support mode.
  • The feed for Yokai is identified as a strong crimson on the camera selection HUD.
  • Yokai will lose signal and deactivate if it moves outside the defender area and stays outside for more than 3 seconds. The effect is similar to the effects of Mute's Signal Jammer on Attacker drones, with visual disruption before complete signal loss. The line "LOSING SIGNAL, GET BACK INSIDE" will appear on the HUD when losing signal.
  • Echo is immune to Dokkaebi's Logic Bomb, having developed their systems in tandem with each other, alongside using a wrist-mounted device to view cameras instead of a phone.


  • An exception to the Shock Wire destroying allied gadgets, Yokai is able to touch Bandit's Shock Wires without being destroyed. Thus, Bandit can work with Echo without worrying about destroying the latter's Yokai.


  • Yokai is a remote-controlled electronic gadget. However, it has certain characteristics that are shared with electronic gadgets that are "on-person".
  • Thatcher's EMP Grenades will only disable Yokai for five seconds before reactivating. However, it will drop to the ground if it was attached to the ceiling when it was hit by the EMP.
  • IQ and her Electronics Scanner can quickly identify Yokai's location, making her the most dangerous detriment to Yokai's survival.
  • Twitch's Shock Drone destroys Yokai with a single shock dart, but it is unable to see it when it gets cloaked.

"Hovering drone that releases disorienting sonic bursts. Yokai also transmits a video feed to the Operator."
— Yokai Description

Wanting to circumvent ranged weapon limitations, Echo crafted Yokai, an unmanned hovering vehicle. Equipped with an acoustic hailing device, this signature drone can fire ultrasonic bursts that disorient all targets in a given perimeter. Yokai also transmits a video feed to Echo, who keeps his immediate perimeter secure. Embrace the power of technology and embody a turret Defender who can both hold up the siege and support roamers.[2]
