Blackchain is an Ultimate Move performed by Deku using the Blackwhip and Fa Jin Quirks.
Description#
By combining the strength and stretchiness of Blackwhip with the stockpile power of Fa Jin, Deku creates a chain to ensnare his opponent. He is able to use this chain to throw his opponents great distances.
Deku first uses this move against "Tomura Shigaraki" during the Final War, throwing him across the U.A. Flying Fortress.[1] He uses it again against Tomura, keeping the villain's arms restrained on the battlefield, rendering him unable to use his Quirks.[2]
He later uses it again in combination with Gearshift to sprout a web of Blackchains from behind his back in an effort to attack and restrain Tomura, but it was easily evaded by him, using his recently acquired Danger Sense.[3] To counteract this, Deku applied Transmission's Low Gear to Smokescreen to slow down the smoke and sprouted several Blackchains to keep Tomura's Danger Sense constantly active, allowing him to catch the villain off-guard.[4] Later, he uses Blackchain to rip the earth from underneath Tomura, launching the chunks of ground into the air and preventing the spreading of Decay.[5]
