Mad Endo - another personal favourite of mine! Hope you guys like this rendition! (Fun fact: I drew at least half of this on a school bus without any reference image. :>)

I love the potential a character like this always seems to have in terms of being memorable; there's so much character development that can be done with this concept.

I personally envision Mad Endo as a power-hungry being, who doesn't really cooperate with others for the sake of teamwork - he does so for his own personal gain. A wildcard. He is addicted to the soul energy powering the denizens of FNaF World, the essence making him gradually become stronger and stronger. Such power, of course, drove him mad. Yet, as is the case with most addictions, Endo was still unable to satiate his hunger for this energy.

When he consumes too much energy all at once, his body becomes completely unable to handle it, and begins venting any excess out immediately.

This process transforms him into Overclock, a wild and unpredictably dangerous being. Allowing the Mad Endo to attain Overclock status would be an...unsatisfactory endeavour.

His design is just great to me. I love his skeletal look (Duh, he's an endoskeleton), and I really tried to place emphasis on that aspect of his look in this redesign. I provided him with a ribcage - it lights up a bright orange when he Overclocks, as do many different segments of this design - as well as defined cheekbone-esque protrusions from his face, to make it more reminiscent of a skull as well as to add to his creep-factor.
