No more than thirty seconds deep in his trek into the murky darkness, Abel halted once more as he became aware of the ground faintly shaking beneath his feet. After quieting his breath, he quickly discovered that with every reverberation there came an accompanying noise from up ahead. Judging by his sense of hearing alone, Abel guessed that it was still several hundred feet away, around some sort of bend, and well beyond the range of his unpredictable electric light. He turned to Bridgett and exchanged a look with her, which she returned knowingly. Both suspected some sort of massive Grimm causing the tremors, and even though they were freshly free of a near-death encounter, neither felt like fleeing.

The sound of automatic gunfire, far more punctuated than that of a rifle, caught their attention. Without hesitation Abel took off running, swinging the Ampere with each stride and making its light even more frantic, and his partner followed close behind.

Upon rounding the bend, he beheld the scene. At first he didn't quite understand what he was seeing; when the mecha unleashed another fusillade of machine gun fire, illuminating its massive, inorganic form from the front, he quickly caught on. Despite the terrible light, he could hear and dimly see two humans fighting the thing. Truthfully, 'fighting' seemed an overstatement—at the moment, both were struggling to stay alive. They needed help.

Without waiting for any sort of confirmation from Bridgett, he ran forward, feet pounding against the railway. The urgency of his impetus effectively communicated his intentions to his partner, who ran after him. As he moved, Abel brought the Ampere level with the massive robot's back, waiting just for a moment to get a better idea of its scale. The thing absolutely dwarfed him, almost scraping the train tunnel's ceiling, which constrained it somewhat. Making a rough estimate as to the location of the mecha's upper back, he channeled his semblance to fire off a lightning bolt.

While the surge of electricity didn't seem to damage the mecha -or even stun it, for that matter- it managed to acquire the robot's attention. Its waist swiveled around to face Abel, leaving its back at roughly 60* angle to Gren. Abel, meanwhile, became very aware of the fact that the humongous machine's focus was now on him. [b]TARGET ACQUIRED[/b], it thundered, and Abel let go of the Ampere. “Please work,” he begged, and threads of electricity linked his hands and his weapon as span it at high speed in front of him. When the mecha opened fire, showering with bullets, most were intercepted by the spark-wreathed Ampere, sent flying off to the side or ricocheting back. One out of every hundred or so penetrated his makeshift barrier, however, and one of them grazed his cheek, making him flinch. “Do something!” He bellowed.
