One such appearance where a foe took advantage of his limitations was in "Iron Man" vol. 3 #15, where he was hired to kill Tony Stark. A fight occurred between Nitro and Iron Man. Iron Man, whose sensors and telecommunications gear had been recently upgraded, noticed that every time he exploded, a high-frequency pulse was emitted by his body. Experimenting, Iron Man duplicated the pulse, causing Nitro to explode. After he exploded several times in a minute, he passed out from exhaustion (presumably, it takes energy to explode, and he could only spare so much before he passed out). Iron Man then handed him over to S.H.I.E.L.D., along with a recommendation on constructing a null-harness. He was sent to prison.
