Feral Humans - Krogg Warriors

They need to be bigger man. Right now what you have is a penal legion squad from a traitor guard army, they just aren't believable as orks yet.

Never fear though, I have an idea on how you can achieve that. Make them BIGGER!!! They are already jacked, but not beyond the realm of feasibility. Use the above guys for a mob, they'll be fine for it, but you will need more to make your 'ard boyz and Nobs. Here is how:

You will need some ork boyz bits as well as the marauder sprues you have been working with for this conversion. Its simple really, just take the ork arms and cut off the hands. Replace the ork hands (Which are stupid big.) with human hands from the marauder kits, by pinning them on, some green stuff to make the join look more realistic may be neccessary, and throw on whatever assorted weapons you want, the Ork ones would look big but would be cool in small quantities. Test fit the arms onto the human torso from the marauder kit so that the bottom of the ork arm is in line with the bottom of the arm spot (connected to the lats.) untill you have a pose you like. Once you have a good pose glue them in place and and finish the assembly minus the heads.

Ok, now for the putty work. Using green stuff you will need to fill in the gaps between the arms and the torso by sculpting additional muscle into the shoulders, back, and chest. Try to be subtle with the green stuff but make it clear that these guys essentially lack necks. While you are doing this test fit the head so that you get a really good supersteroid look to it, If you took off the hair from the marauder heads you'd get a great "HULK ANGRY!!!" expression that will look hilarious and awesome with the super shoulders. Once this is all done let the putty cure and later on go back and increase the bulk of the thighs with green stuff. All of the models are wearing paints which is good for this, so all you will ned to do is sculpt the impression of massive quads rippling under the fabric, look at jedibribo's gallery for great examples of what super steroid thighs look like (I'm sorry Jedi but there is no way those things are female.).

The real key to pulling this off right will be to throw in some body builder joke models. Here are some ideas:

• Using the arms which hold things in the air make a dude flexing while looking at his biceps. The IG hand pointing its finger would be classic for this one (ie: Which way is the beach...).
• On a battlewagon and just about all of your vehicles just clutter about converted "mad max" type weight lifting equipment. Don't bother going to the gym, these guys will bring the gym to you!
• For the nobz especially make a bunch of incredible hulk jokes. Have guys smashing things like the hulk does, grab any good hulk comic and you'll know what I'm talking about.
• For a killer kan unit buy 3 Imperial Guard Ogryns (Sucks that they are all metal still, we need plastic ones as they are sick now.). These guys will be a synch to convert into a megaroid disaster/success by just sawing off the head and converting a normal human head to go in its place! Just add extra muscles with putty, some supersized chainswords (Just pin two/3 ork chainblades together and replace the grenades in the hands with the chain blade, should be relatively easy to do.), and a bit of extra armor plating (Or just laugh at those puny weapons...) and you will have an amazing looking set of vehicles that are hilarious and fit your theme perfectly.

I hope that I've helped with this one man, this army has potential but will need a bit of work for it to not require your opponent to suspend his disbelief for them to represent orks.
