[I'm more of a Luxord fan, but since his name was previously taken...I chose Vexen 'cause he's a scientist, and so am I, sorta...

Y'know what? Seein' as I'm Vexen, I might as well role-play him! I'm gonna go full extent and try to act JUST like him on sheezy. If'n you want a real conversation, then just start it with "NO-V", whether in the subject, or in the beginning of the PM/comment.
Now...*ahem*]

Even Report #1 (this one is completely original)
I had been surprised! Braig had chosen his own son to become the first in our experimentations. I didn't care, he wasn't my child, but it was slightly disconserting. Although, he was an illegitimate child of Braig, notorious for sleeping with whores. Drance, Braig's son, had shown complete ignorance and gullibility about our experiment, willingly just waltzing in the tube without any hesitation. I noticed at the last second, before we had started to separate his heart from his body, that he had a sad and understanding look on his face.
Our experiment had proved a success! Not only did we manage to keep the heart unfazed, but also, the body had retained it's form, unlike the other ones, where the body whithered away and these "Heartless" beings appeared. When the subject had awoken, he had no knowledge of his previous life. Braig had accutally looked saddened for a fraction of a second. Having Braig's charisma, and scientific help from your's truly, he had instantly bonded with all of us.

Even Report #2 (completely made up)
I have come across even MORE exciting news! Before we had started another experiment, another being had appeared from Drance's body! It was a girl, it is unknown-even to me-how this had happened, who looked similar to him, except, she had referred to herself as Drecxan. After that, Drance had started referring himself as Candrex, never really responding as Drance after the experiment.
Drecxan has apparently been able to control the Gravity and Magnet elements, being able to create small black holes and being able to make intense gravitational pull. She has shown excellent mastery of this. These beings have made me create a hypothesis as to that all of these beings, devoid of darkness and light, if they have a strong enough heart, can control a certain element. But that question, if you can call it that, brings up many more. I will have to experiment soon.
Candrex has shown that he controls Energy, changing objects into pure-energy forms of themselves, and also being able to single-handedly power the entire complex! I will soon seal him in a non-breakable test tube, when he has achieved something great that he can take away...I'll just soon have to wait...
I had had enough! I was bored of not having a subject to experiment on in a week! I had convinced Ienzo to let us dive into the World's heart, having wanted to do that since we had first found it.
We will soon make our trek into the heart, none of us knowing what's going to happen. It is only the apprentecees that are proceeding...

Eve--Vexen Report #3 (based on knowledge attained from games, same goes on for the rest of them, unless told otherwise, and a little fictional info)
Hakaka! Hello, I'm Vexen. I used to be a clouded soul named Even, but I gave into the darkness, along with my associates, Xehanort, Braig, Dilan, Eleaus, and Ienzo. I was the scientist of the group, being the first to learn how a Nobody like myself to keep his form. Sadly, I'm the second oldest of Ansem the FOOL's apprenticees. I had also discovered that when a powerful Nobody is formed, they are granted a sort of manipulation of an element. I have achieved the chilling power of Ice. Being the most academic of the Organization, I have named myself the Chilly Academic. My mind, devoid of the mind clouding emotions, has improved a great deal, making me see things unlike before!
I have done it! Since Drance's...Candrex's assignment to create a fortitude purely for us Organization members, I have introduced Candrex to his heart, making him AND his female counterpart into Wastes, Nobodies who have only partially merged with their heart. He has lost almost ALL his powers as a Nobody, not able to command powerful Nobodies (he controlled the Twilight Thorn Nobodies), and not able to move through the Dark Portals. He is, however, still able to use his elemental powers, but seeing as his recovered memories have jumbled with his Organization memories, our former #7 AND #8 have become no threat to any of us. Hekekekekekekakakakaka! Fwohohohokokokokohahahahakakakakahehehehehehehehekekekekeke!

Vexen Report #4 (a little bit in the first para is made up, easy to guess what)
I'm sorry I haven't made a report, whomever-has-found-this, but I had been stationed to Castle Oblivion, along with Axel, Lexaeus, Ienzo, Marluxia (the fruit), and...did I just hear Marluxia scream "I'm not a fruit, I'm a flower?" anyway, and also Larxene. I had forgotten to make a report since getting here. I curse the Castle's powers, and I curse Dran--Candrex for making the Castle affect EVERYbody BUT him and his female doppleganger. I have started to make a replica of the silver-haired boy who had entered recently...I can't wait to see the results! Hakakaka!
Hekekekeh, I'm gonna go find something, or someone, to experiment with! Hekekekeh! Fwohohohoho! That miserable Riku Replica was worthless! That mindless Sora defeated him 4 TIMES!!! Maybe I should make a new, original Nobody for that flowery wuss Marluxia to use. It's gotta be big, have at least a couple of scythes, and have flowers...I think I can do that! Maybe I can get it done before I'm somehow eliminated...
I was amazed how MY Nobody turned out! It was gigantic! I was so proud of myself, that I created a clone of Marluxia, one that was destined to fail, but still give Marluxia valuable time to merge with the Nobody.
I feel my inevitable defeat looming, don't know when or why, but I know it will happen. Sora is showing strength beyond compare...I just hope my subject Nobody is enough...

peace!
