Creating Chaos Spawn

Illustration from the Chaos Space Marine codex

"A Chaos Spawn is a mindless mutant creature who once belonged to one of the intelligent races of the galaxy and who has become so mutated through his or her servitude to Chaos that he or she has devolved into a twisted and insane abomination. Those seeking immortality and power through the ultimate attainment of daemonhood in service to the Ruinous Powers face the constant possibility of being reduced to Chaos Spawn, either by accumulating too many mutations or being cast aside by their Chaos patrons as unworthy of further advancement because of their consistent failure to serve the will of the Chaos Gods. More simply, they may lack the inherent qualities required for successful leadership of other Chaotic servants and thus be of no further use to their patrons. Chaos warband members who are transformed into Chaos Spawn will either be abandoned by their former comrades or kept as pets or as cannon fodder, to be herded into battle along with the rest of the Lost and the Damned." - Warhammer Wiki

Stepping into the world of Chaos with my Space Marine army I was expecting Chaos Spawn to look like a mix of the Thing and Tetsuo in Akira. Instead we are faced with this:

Rather than investing in these PG certificate daemons, I decided to make my own out of spare bits and greenstuff. this is the result.

In making this chaos spawn I wanted to get across the hopelessness of the champion that has been corrupted.  Cursed for being unworthy of the power that they could not comprehend.  I intend to make another five in time, but for now this little chap should do.
