With barely any time to react at all, Magnestar attempted simultaneously to leap out of the way of the blades, and away from the droid, while unloading her clip of ball bearings into the hole she had made. Once clear of the droids reach she called out, "Keep it steady!" She knew that it wouldn't want to move anywhere for fear of exposing the hole inside. That was fine, with her ball bearings inside of it, she could launch them around all over the inside of it ripping through control panels and servo motors and sensors until it finally shut itself down, or was unable to continue operating.

To do this, Mako closed her eyes, trusting her teammates to keep the droid from moving anywhere, and focused all of her senses on her magnetic abilities. She was looking for the 19 ball bearings that she had rolling around the inside of the Omnidroid. Once she had one she focused on it and pushed it straight away from her with as much force as she could. More than likely it would just roll along the inside curve of the spherical foe, but once it had made it half way up the arc she would draw it towards herself as strongly as she could, trying to draw it through the center core of whatever it was that was in there. She would move the next ball bearing the same way, and the next and the next until she had a swarm of them dancing around inside of the machine. Of course, this much control required more than just mental commands, this required a physical exertion as well. Using finely trained physical moves from her own brand of Ninjitsu, she spun and kicked and punched like she was fighting an invisible opponent with her eyes closed, in an effort to keep the small metal missiles spinning inside the Omnidroid.

With the hole Magnastar was able to open up in the Omnidroid, Cassie knew it was time to finish this. She made a gesture like a conductor urging the orchestra to a crescendoed finale, easing her hands in front of her, palms upward. The acoustic traps she had laid out switched back to the frequency that she believed was as close as she could get the droid's resonant frequency and amped up the volume. A perfect shape, like a sphere, was great at redistributing stress. However certain stresses, like harmonic stress, tended to concentrate at flaws and imperfections: chips, cracks, fractures, etc. It was Cassie's hope that the hole Magnastar had carved would be a great focal point for her acoustic stress to concentrate, and that the material, while a metal and therefore malleable, was hard and brittle enough to actually start shattering.

Coming under attack from all sides, the Omnidroid seemed to realise its time was almost done. It hunkered down, protecting its vulnerable underbelly and ceasing its attacks on the supers to focus on protecting itself. Even then, it was losing ground. Elastigirl had one it is claws all tied, up, while Karearea and Mr. Incredible worked together to smash it to bits.

A trapdoor opened in the robot's side, and a rocket launched out from the gap. It wasn't aimed at any of the supers, going well over all of their heads. Instead, it arced out over the city, headed for somewhere over the far side of Metroville. None of them could quite see where it landed, but only eerie silence followed. There was no explosion, or loud noise, or other form of destruction reaching into the sky.

Back at the factory, the robot gave one final shudder, collapsed, and then exploded. Mako's internal damage combined with Cassie's work on the armoured shell did their jobs well, and the machine simply couldn't keep going. The Omnidroid's death throes lit up the night for a second, and let out a booming report, before falling still and silent again.

Around the factory, a few flames still flickered, though most had gone out. The place was a terrible mess, but for now at least, it was safe.
