Here is a few variations that don't get much play:
1. Bio-devices. Examples being the Guyver suit from the Guyver anime. Great power armor but what happens when it becomes organic? But a section on 'living' devices would be cool. Like alien tech that dribbles into superhero settings from time to time.
2. Robotic companions: Dino-mutt anyone? K-9 from Dr. Who is another example.
3. Giant Robots: A variation on powered armor actually, I know Ult: Vechicals does the technical breakdown but say something an evil scientist uses would be nice.
4. Spy gear : Beyond the utility belt. Computer hacking tools, laser cutter pens, anything that Q might have dreamed up at one time. Super X-ray binocs, grapnel system, THE SUPER CAR!
5. Drugs, Drugs, Drugs! Anti-super drugs, Temp-super drugs, strange alien virus that give psionic powers sold on the market as a headache medicine. Etc.
6. Power amplifiers. Aid to be sure, but some creative versions. Like a helmut that gives people a massive 'creativity' boost...but at the cost of slowly driving them insane.
I'd love to see devices that have real cost to use them too. Radiations, side-effects, mental aberations. Just the fun stuff.
Sure Dr. Omazo's death chair allows you project your will to kill people, but did you know it caused brain cancer in the user? Mwahahaha!
