A few years ago I published a composite graphic consisting of several concept designs I created for Neo Cortex in January 1995 when developing Willy the Wombat which would become Crash Bandicoot. Here it is again for the benefit of Crash fans who've never seen it.
There were also several other sketches I created of Neo Cortex as the character became more defined. These have never been published before. I forgot about them until they were rediscovered when I was going through my Crash Bandicoot archives recently. Here's three more unseen images of Neo Cortex. Hope you enjoy them.
