Super powers are awesome.

Shadow Strings: Cassie can create shadow strings from her fingers. If she can attach these strings to at least 5 strings to a shadow, she can manipulate the person whose shadow the strings are attached to, like a puppet… Except not really.

Shadow View: Cassie can completely judge an event from watching the shadows. As a result, she doesn’t need to look at a person to see their attacks and dodge or counter.

Shadow Growth: it is a well known fact that when in different amounts of light, shadows lengthen or… shorten. Cassidy can grow as tall as her shadow, her strength growing in proportion. For example, if her shadow is twice the length of her regular height, she can choose to grow to that height, and her strength will double. However, at such a size, her speed is also cut in half.

Shadow Elements: When her shadow touches another element that was caused naturally (not someone’s attack. Something like a body of water, trees, etc) her chakra takes on that element. As a result, she can temporarily use basic attacks of that element. Ex, her shadow touches a pond. Her chakra element is temporarily changed to the water element. She can use basic attacks such as water bullets, etc.

Hide and Seek: Cassidy’s body temporarily converts into shadow particles, making her appear as a shadow. As a result, she can jump in and out of shadows in the surrounding area for both quick travel, and concealing her presence. If for whatever reason, all the shadows in the area are cast away, she will rematerialize normally.

Emotion tracking: Cassidy can track and count the people in a set area be sensing their changes in emotion. (The area can differ depending how much energy, chakra and concentration she puts into it. As a seventh rank, the area isn’t very great as of yet) She can’t read the emotion, she can just find a person’s position.

Thought tracking: Same thing as emotion tracking really, except instead of sensing changing emotions, she can sense change in thoughts. For example changing from “Okay, now I’m going to use substitution jutsu” to “I wonder what’s for dinner tonight” would give away someone’s position. Just to clarify, she can’t read the changing thoughts. She can just sense the fact that they are changing.

Luminescent Orbs: Basically, they’re orbs of light. They don’t do much for inflicting damage to an opponent, but they illuminate the area and can pierce through weak darkness attacks. Also, by lighting up an area, the shadows are lengthened, which would be of great use for her other jutsus.

(Not done yet, kthx.)

Kimi has light bubbles....

Maybe change bubbles of light to say.. floating spheres that illuminate the area and stuff. Kimi's Light bubbles are almost completely different, you'd just need to change the name and what they are.

Aren't Kimi's bubbles elemental? O:

Yeah, we said they were different, just the name is the same. So all Lucy was saying was to change the name so theres no confusion.

Well this ISN'T my character but I'll tell the person to change it to this awesome new cool name for em....I'll tell her to name them Luminescent Orbs or Globes...

D:
I are sorry. Didn't know you had bubbles. But basically, it's like Lucius said. They're more orbs of light to light up an area. I called them bubbles to describe how they looked. I'll change the name and no harm done?

Yep, no problem; thanks
