...and that's when there was a low rumble from the east, and with no warning whatsoever, something flew over the heads of the assembled heroes. Something that made a titanic CRACK, and a concussion that knocked over glasses, and scattered plates of food, and kicked up a layer of dust from the ground. Paper debris and a dust haze swirled in a long vortex in the thing's aftermath.
It was hard to say what it was. There was a golden metallic gleam to it, and it was far too small to be a manned aircraft. Bright blue radiance spilled from behind it as it arced up high, looped around, and headed back towards the gathering! This time mundanes went under tables for cover, and some of the more hot headed of heroes were taking aim when there could be heard the definite sounds of...music?
A deep, pounding bass pulse announced the return of what turned out to be a humanoid robot, or perhaps some kind of armored suit. It had sleek, smooth lines, marred only by what looked like some kind of gun emplacement on its right shoulder, and a streamlined pillbox on its left. On its back was a winged jet pack...its wings too small for lift, they probably only provided control surfaces. The entire thing, from helmet to rocket boots, was made of some kind of shiny gold metal that sent slivers of reflected light scattering around all over the place. The radiant blue exhaust from the pack, and from additional thrusters in the feet, kicked up a strong wind that roared around until it finally came to a vertical landing, right in the middle of the congregation. A powerful, deep voice then proclaimed...in a cadence timed to the music's beat..."LADIES AND GENTLEMEN, INTRODUCING PRODIGY AND THE GOLDSMITH!"
The suit raised both its arms in a celebratory sort of pose, and it began to change. With whirring noises, the weapons on its shoulders partly retracted, unfolded, then clanked down into new configurations, forming larger epaulets. The jetpack split along multiple lines, and redistributed itself into a series of thick plates over the suit's chest and abdomen. Other changes took place internally, gauging by the noises involved. When it was done, the robot suit was thicker across the chest and arms, and significantly more armored-looking. On the other hand, both its guns and jetpack were visibly missing.
"Thank you!" said a voice from the suit...not the deep male one from before either. No, this voice was definitely female, though electronically modified, by the sound of it. "Thank you so much!"
