Some devices that those of you who want to go with a mechanical or technological direction for your characters might consider include the following...
Guardian Exoskeletal Battlesuit - Resembles a full-body (include mask/cowl) spandex costume, but generates force fields, allows flight, and fires energy blasts, designed by a Canadian scientist.
Pym Particles - Enable one to shrink or grow to great heights. Can provide size-changing powers with enough exposure. Limited uses can temporarily shrink opponents (especially if you grow to great height, pick them up, and shrink back down to normal size with the opponents in your hands).
Ant Man Helmet - Generates pheromones that allow one to control and communicate with great numbers of ants. Someone with enough super genius and technological/entomological know-how might be able to shift it to other sorts of insects.
Arcade's cybernetics - Abandoned underground amusement parks with deadly rides, lasers, saw blades, and robotic duplicates, as well as many high-tech variations on typical clown tricks like water (or acid) shooting flowers.
