Thaddeus

Maybe some of you (probably not) remember the little white sphere with the green swirl that somehow tiptoed into my pictures.

That's my sidekick, Thaddeus! c:

Thaddeus is a... little white sphere with a green swirl... that can shape shift into different forms.
He can shape shift into different weapons during battle. The bigger the weapon, the more energy is necessary.

Nikki and Thaddeus connect mentally during battle, so depending on their relationship with each other, they can either kick ass or kick each others' ass.
Because Nikki spends most of the time exploring her own mind, she can usually overpower Thaddeus when she feels such actions are necessary.
Like when they're deciding on a default appearance, which much to Thaddeus' dismay, is a cute little puppy... thing.
He was upset until a few ladies walked by and cooed over how cute he is.
Thaddeus loves the ladies.
If he's overly provoked, or is very passionate on the subject being debated, however, Thaddeus can sometimes take over control of their actions.
To make things a little more clear:
They both mentally connect during battle, and make decisions on what both of their bodies are doing (Because of the mental connection, this is all happening at speeds appropriate for an intense battle). If they're getting along, their movements usually compliment each other, and things go rather smoothly. Now, say, if they were in an argument, their actions would be less smooth, and most often, both would only have control over their own bodies, and they would have to do guess work over what each other is about to do. That usually doesn't end well.
In more severe cases, one might forcefully take control over the actions of both bodies. If the two are both fighting for overall control, both bodies could take damage, depending on how intense the mental competition is.

Thaddeus is, in general, a shit-stirring pervert. But everyone still loves him. He usually doesn't get on fair ground with those a little older, a little wiser, and a bit more rough around the edges. But of course, those are always the people that usually decide his fate, aren't they? As cunning and sly as he is, Thaddeus usually gets his fair share of kicks in the ass for his misdeeds. In the end though, we all still love him. The goddamn perv.
