Recipro Burst is an Ultimate Move performed by both iterations of Ingenium, Tenya[1] and Tensei Ida[2] using the Engine Quirk.
Description#
Tenya activates Recipro Burst by forcing the torque and RPM of his engines into overdrive. This grants him explosive power and incredibly fast speed for ten seconds. After the time limit is reached, his engines will stall for a short period of time.[1]
Using this technique, Tenya was able to propel Team Todoroki fast enough to steal Team Midoriya's headband in the blink of an eye.[1] He also uses this move to enhance the striking power of his kicks, able to deliver multiple powerful blows in quick succession.[3]
Not even the agile Hero Killer: Stain is able to avoid all of Tenya's kicks effectively while Recipro Burst is active.[4]
Tenya has also combine Recipro Burst with Izuku Midoriya's Full Cowl and Eijiro Kirishima's Hardening to break through a wall and launch themselves on Shoto Todoroki's ice ramp to fly across the battle field while rescuing Katsuki Bakugo.[5]
Tensei used this technique against Monster Cat.
Variations#
Recipro Extend: The radiators installed in his hero costumes legs allow Tenya's engines to cool much faster than normal. Once they are ready to be used again, Tenya can use Recipro Extend to gain another burst of incredible speed.[6]
