What named creators run on Echo, and every option the game allows. Plus the gadget interactions that decide the matchup.
Primary and attachments: NotJoeyBlack and Rasco100's pick. The secondary list is every option the game gives Echo; nobody we read picks between them.
Rainbow Six counters are gadget interactions, rules of the game rather than statistics, so every pairing here comes from the two operators' own kit pages: the mechanism from whoever wins it, the gadget it beats from whoever brings it.
Brava's Kludge Drone hijacks the Yokai, which is the whole of Echo's kit: the video feed and the disorienting burst both change hands.
Echo plays as a turret Defender through the Yokai's video feed, and Dokkaebi's Jegeo Payload takes that feed away.
The Yokai's value is the feed it sends Echo. Nokk does not register on it, so a drone hovering over her route buys him nothing.
An Exothermic Charge has to be placed and then survived. A Yokai burst from the ceiling disorients whoever is standing at the wall, which is the one moment Thermite cannot be anywhere else.
Grim fires the Kawan Hive into a room and follows the intel in, and a Yokai holding that room disorients him at the doorway the swarm marked.
Echo is a Defender in Rainbow Six Siege.
Rainbow Six's counters are mostly deterministic gadget interactions, rules of the game rather than statistics, so we state them from the two operators' own kit pages with no telemetry needed. A pairing is only written where the winning operator's page names the mechanism, which is why plenty of operators here carry none. Statistical data is based on external APIs and publicly available information. It may differ from official data.
NotJoeyBlack, Rasco100 and SINOOS publish loadout picks under their own name, and this page credits each of them rather than averaging them into a single answer. We measure nothing ourselves. The list of what Echo can equip is the game's own, and is separate from anyone's opinion about it. Statistical data is based on external APIs and publicly available information. It may differ from official data.
