Thankyou for your in depth and helpful reply CraigD. I have spent the days since your post digesting the information and suggestions you have made. And I have made some serious headway into solving problems. Yay! A packet of Tim Tams are your reward. I like this angle too. I've been playing out a number of backstory options, and I've developed a fairly decent one regarding the genetic alterations happening to his zygote. You are correct, highly specified training is the more effective and plausible way of creating a super solider. I am however, still thinking of running with a combination of training and genetic alterations, but limiting the number of alterations. I'm thinking of keeping the muscle enhancement via blocked myostatin production, as we already know that this is possible in humans. I'm also going to keep the 'warrior gene' but limit it to the one and make it already part of his DNA (they didn't introduce it - so did they miss it??? :o Stay tuned!! ). This helps another element in my plot development, and steers it away from any 'Incredible Hulk' aggression-related similarities. :) I'm also definitely keeping the unihemispheric sleep ability. I know humans that can make cups of tea and hold conversations whilst sleep walking, so perhaps it isn't such an unbelievable reality. And besides, it's just way too damn cool not to have it!!!!! B) I am glad my biochemical stuff appears correct - with all the reading I've been doing I feel like I've been studying for Year 12 final exams! And yes, I am here for criticism and correction, all this biochemical stuff is not my field of expertise (I'm not even sure I have a field of expertise!?) Yes, I deliberately haven't mentioned any non-biological enhancements as I didn't want him having any. I was trying to stay away from the Van Damme UniSol-type soldier, and for a reason. This guy is the result of unauthorised (?) experiments performed by a high covert project. This guy has to be able to infiltrate criminal organisations, countries of 'concern' etc - he needs to look normal. I've had all sorts of wonderful ideas involving nano technology and brain implants and computer chips and kick-*** weapons....but that's not really where I wanted to go with him. (Hmmm - I might have to create a different character to use all this fantastic technology and the genetic enhancements I ditched.......so many ideas.......) So are there traits that I should be amplifying to create a super soldier? What areas have I missed, do you think? I am not against the idea of nanites, if it will help create and sell the idea of him being this super soldier. I was trying to keep him a 'complete' human, but I may need to forego this, and introduce some implant technology. I'm not sure. I got the idea for the 'warrior gene' from an episode of CSI that aired here a couple of months ago. The killer in question was trying to convince a jury that he couldn't be accountable for his actions, his 'warrior gene' made him do it. It was then that the CSI investigator explained to the jury that he also had the 'warrior gene' and yet he wasn't a serial killer, he had made the choice to be good, to do good. You may or may not know what I'm referring to. This was the light bulb moment for me. Without giving away the story this was the key piece I needed for the audience to 'like' him. Yes, he is the ultimate antihero - he murders, tortures, threatens, extorts, etc - but he's doing it to rid society of the unwanted - murderers, rapists, drug dealers paedophiles etc. My guy is choosing to do good on behalf of the good people in society, therefore we forgive him for choosing such a violent, and normally, society-rejecting approach - we actually champion his cause. As you correctly said, training is the key and his training is extreme - military training from Army, Navy, Marines; special operations training, stealth and infiltration training, hand-to-hand combat, several martial art forms. He has had weapons training (skilled marksman) but his skill at hand-to-hand combat is his trump card. I agree that his training and how he thinks as an individual is the more likely road for super soldier creation. But I would like to combine this with his genetic alterations, making his existence and creation both possible and highly unlikely at the same time. I think he will require training to be able to direct this aggression to the correct party - I'm thinking some kind of extreme mental training, but not as far as hypnotism or brain washing. My main point is as the story progresses, he begins to understand that he does have control over who he is, he controls his actions, his decisions. I just don't want to get too heavily into the whole brain manipulation scenario, it's too complex for what I'm trying to do. I'm going to have to do some more thinking on how he is trained to control and target his inherent and learned aggression.
