Mental power telekinesis will throw random throwable objects at target if you have super strength iconic even large buses will be thrown. Unfortunatley it does not work on most episode throwables .
To be more clear, Electric has: Attract Repluse Flux is a magnetic force shield. Static Push Electrostatic Bomb -- non raid adds get pulled/knocked around. I don't think any of those actually throw metal objects around, but they're all clearly magnetic powers.
I wouldn't mind more lunatic/puzzle solving powers i.e Riddler/Joker or a Possesed type of power i.e as a host of spectre/Trigon or Darkseid you would wield some of their powers to a lesser extent ofcourse. would be cool.
Realistically it's unlikely that a whole new power will get added, though I think it was mentioned that maybe it would be possible to "reskin" some powers. I think that's what they did with Cosmic Boy. Personally I think it would be much more doable to reskin some powers to add additional powers. That way it HOPEFULLY* appeases those who want new powers, but also is more affordable and doesn't take as much time to create. (*I say Hopefully but lets face it. Even if the devs meet us half way, there will still be people who b*tch and moan about it)
Would be cool to throw giant metal constructs and weapons around, have metal pets or minions beating everyone up. Maybe it could be a tank power and you could make yourself a suit of armor and stuff. Would be cool to have metal beams and pipes (or swords??) burst through the ground as an AoE. Maybe your magnetic powers would have you using stronger metals, some made up metals, as you get stronger. Would be cool to make stuff up for it. But I feel like most people would just tell you to use electricity. I remember everyone was against having a water powerset because... We had ice.... No imagination on the forums.
