Creatures Caves

Warning! Might contain spoilers about agents for the CCSF 2010 and general future releases!

Okay, after some asking around and looking what others want I reduced my to do list on some bunch of agents. This topic should help me to bring them in proper order. I would do this over a poll, but that function of CCaves is frankly said too limited, at least for what I need this time. There will be (as I hope) at lot of discussion and personal opinion why which agent got what place.
Sooo, your job is pretty easy. Read the list and the descriptions and then tell me what you like the most/fewest, which I should make and why.

THE LIST!

1. CRC v.2
Pretty self-explanatory. The CRC was the Creatures Remote Control. It was able to read a creature's mind and modify it, so it forces them to do some certain actions. Version 2 will be pretty much the same, just with more different buttons, a custom action line and an instant kill button with R-U-serious question.

2. Marx / Marx Soul
You might know him/them if you played Kirby Super Star or Kirby Super Star Ultra. Marx and his stronger and sorta zombified version Marx Soul were bosses there.
To the Creatures-related part: Marx would be some kind of prankster-like critter. There only will be one Marx at once in the whole world. He would fly around and attack your creatures in various ways. The actual attacks wouldn't harm (and when then only a bit) your creatures and will sometimes have pretty surprising and crazy effects on them! As I said: pretty entertaining

3. Doomsday Device AKA DDD AKA Triple D
The DDD would bring the doom over a single metaroom. It would include the whole package: thunderstorms, tornadoes, meteor rain, perhaps some earthquakes and so on.
The whole procedure would kill all life in the room and make the whole room infertile for some minutes to hours (depending how the basic fertility was before).
Probably would be interesting in combination with the Zombie Project...

4. The Auto Hand
After all this chaos and destruction the Auto Hand would be a nice thing. It would be classified as hand, can be pushed, pulled, hit and eaten (not lethal).
Via an extra panel the Auto Hand can be programmed to do some basic actions. Some examples would be "punish all creatures who try to do 'hit elevator'", "keep all creatures from agent X (e.g. the HLM) away", "kill all ettins entering a certain zone" or "praise all creatures for pleasing hunger".
This would be useful for people who like the Wolf Control, but have problems with mass deaths during WRs.

5. The Ubersplicer
The ultimate splicing utility, even topping my Supersplicer. The splicing routine would be improved for more "fairness", it would be able to generate one or even multiple creatures/eggs from a genome directly into the cabin, had a new interesting look and some more functions I can think of, e.g. freezing all creatures or keep them away from eggs in the cabin.

I think I had some more, but I forgot. The most important ones I posted now here. What do you think?
