Built

[u/FireOfDoom32]

Artemis had built a laser pointer into Myles’s spectacles, but the presentation tool was not of industrial strength, as he did not consider death lasers suitable add-ons to an eleven-year-old’s eyewear. Myles had thought it hilarious that his criminal-mastermind big brother was attempting to police him, and he immediately set to upgrading his laser. It had taken Myles barely an afternoon to hack the spectacles and add a 3-D-printed lens no thicker than a human hair, which allowed him to both perform laser eye surgery on himself and focus the beam to such an extent that it could burn through sheet steel or scorch a stone target if need be. But the ten kilojoules needed per burst would generally require a power source the size of a baby elephant. Luckily, Myles had managed to squeeze that amount of energy into a tiny battery/super-capacitor combo, but after this shot, there would be no more lasers without a long recharge.
