Acarestus
The Challenger sighed. It was worse than he thought. The Mahou Kaiju went to deal with a building on the verge of collapse. She would need help getting people out of there... Time... how can I buy her more time? Acarestus thought as he caused his Thorn, now the length of the building, to snap into a straight, rigid state, except for the middle. He swing it so that both sharp ends were in his hand, turned it over, and proceeded to wrap each end around his legs, turning it into a giant pair of stilts.
After landing on the ground on his massive stilts, he strode over to the same building Mothra went to in a few steps, and then stuck the points deep into the tainted ground for firm footing. He then proceeded to create several Thorns and throw them just under what looked to be the weakest parts of the building, willing them to extend upwards and hold ceilings up after landing in their rigid states to offer some rudimentary reinforcement to the doomed building. Acarestus then manifested one final Thorn in his hands, prepared to catch anything he thought looked like was about to fall.
