El Diablos Nacho is character and antagonist from Slugterra. He is a ghoulslinger with power to spare. He was Dr. Blakk's right-hand man.

This massive Ghoulslinger of mysterious origins, with a hole in his heart that's bigger than the deepest, darkest pit shaft in all of Slugterra. He is Dr. Blakk's "special operations" enforcer.


El Diablos is summoned to talk sense into a "mis-informed" jury, or to persuade a potential "business partner" to sign a "most generous" offer. Wielding his massive Growler Kiloton blaster, El Diablos likes to use Nightgeist Ghouls in battle. Not that he needs them to put fear into his opponents, his creepy face does a good job of that on its own.

In "Light as Day", he was carried off by the Shadow Clan right when he was about to kill Kord.  His current fate is unknown, though the two most probable events is that he was either thrown back into the Deep Caverns or killed.  El Diablos comes from the Deep Caverns underneath SlugTerra, as shown in "What Lies Beneath". He worked to make sure that Dr. Blakk upheld his end of the deal with Nacho's master, Brimstone, leader of the Darkbane.
