Chaos players made it to Blood Bowl around 1990 or so. They were suitably spiky and weird-looking. There are some interesting rule variations for using them, IF you can track down the various Blood Bowl books.
The prices vary a lot. A team like the one above might cost you just a little. Check eBay.co.uk for the best selection.
