How Powerful is Crystal form the Inhumans?

It was great to see a little more of Crystal of the Inhumans these past few years in comics. She seems to be an interesting character that hasnt been given much show of her abilities since her fantastic four days as her avengers days she was was usually seen needing help or sharing panels with her fellow Avengers. WHen she became apart of the Kree Empire with Ronan, we started to see abit mor eof Crystals abilities.

So my question to you Viners is this: How powerful is Crystal? Please post scans of her greatest feats or display of power

Little know fact: Crystal can fly on air currents

Ill start it off: (not a powerful display but its a great never the less)

She's powerful but doesn't have great control over her powers which is why she isn't shown to be powerful. Although she has gotten better control of her powers over the years, the royal family sees her as the little kid of the group and try to refrain her from fighting of getting involved in something she might not understand or handle well.

Crystal is one of the most underrated of Marvel's female characters. True, though the fight was in a dream, she beat Sue Storm in a catfight back in Fantastic Four #332. She also effectively defeated the Wizard all by herself in Fantastic Four #81, when the Wizard was getting the better of Mr. Fantastic, the Thing and the Torch. Crystal smashed an entire army of androids in Fantastic Four #100. Does this answer the question sufficiently? By the way, thanks for asking about her. Crystal has been neglected by Marvel for decades, ever since she left the Fantastic Four the first time in issue #105. I am still hoping that she returns for a third stint on the team and that this time she marries Johnny Storm.

Here are more Crystal feats:
