Zennyth uses metal magic most of the time. This metal has to be readily availible for her to use, for drawing metal out of the ground takes WAY too much chakra to be used sensibily in a fight.
The metal that Zennyth uses can be used at any tempurature or density, and is highly resistant to most jutsu types.
Type 1
Heating.
(Latin translation coming soon!)
This will heat up the metal, and anything touching it. It depends on what tempurature Zennyth can maintain.
Type 2
Cooling.
(Latin translation coming soon!)
This cools the metal, and anything touching it. This depends, again, on what tempurature Zennyth would be able to maintain.
Type 3
Morphing.
(Latin translation coming soon!)
This will warp the metal into an object of Zennyth's choice. There must be enough metal to make this, or the object will be hollow, and not very strong.
Type 4
Animation.
(Latin translation coming soon!)
This animates the metal to seem like it's alive. It's not, of course, once Zennyth runs out of magic to use. The only form that doesn't require any magic to maintain is that of Zennyth's familiar, a metalic chinese dragon, about three feet in length.
Type 5
Binding.
(Latin translation coming soon!)
This will try to entrap the opponent or object in a dome of metal. This metal isn't very resistant to jutsus after a few moments, but it's a good way to buy time.
And that's all I can think of... For now~ ^^
