No such thing as a dumb question, only a dumb answer. Here's my dumb answer.
What Erik is displaying is his mastery over the Earth's entire magnetic field. The ground rises up because it's not actually the ground, it's metal particles from the ground, as explained so eloquently by @UGM01. Am I right?
Telepaths and empaths don't give any sort of feedback, if that's what you're asking.
As for your second question, that's a bit more fun. See, I envision someone who can influence both your thoughts and your feelings, which can really be some interesting psychological torture or an instant love potion. Either way, pretty fun to imagine.
That powerset is good for stealth. Terrific for defense too. However, that's pretty much the only thing it's good for unless the user can learn to use these abilities offensively. See, teleporting something into someone else or phasing into someone's body and solidifying is not going to be an easy feat, especially if the physics of that universe don't allow something like that. The user of this powerset would have to be highly skilled in creative applications of their powers and/or have some knowledge of combat in order to be useful.
Invisibility. Pretty weak, but still useful in a lot of situations.

1) I personally think they should be called enhancements.
2) Have some common stuff first like enhanced strength, fire generation, stuff like that, then introduce the more complex stuff like memory manipulation.
How does Splitbrain sound?
...did you consider calling them Shockwave?
Death and Pestilence
A gun. Someone with a gun can kill people. Not too OP.
When I said make a new one I didn't mean continue an existing one that nobody wants to continue
If you really want a roleplay create a new one
Storm is Jewish and Ruby is atheist.
I suppose you could say that.
DNA, Crystals, Carbon
He said elements, like fire or water, not physical forces.
Your best bet would be light. It's useful for blinding opponents, causing optical illusions or, depending on the intensity, burning opponents' skin.
