The ONLY people who know Ezperanza is human, is Armstrong, DiscoHead, Agent K, and Kara. (And ofc Shrike and Beebs but whatever) Without them keeping a secret, Ezperanza, Eskobar would've been EXECUTED ON THE SPOT. But luckily, Ezperanza got her smartness from her dad and his her identity, Eskobar did the same. But decided to use a very unique one..
Btw
Since humans are "illegal" in the Monkey Wrench universe.
How did Eskobar and Ezperanza survive?
Easy. So one time Eskobar got caught by Red, getting locked in a cell and getting examined by yellow scientists. Remember when Armstrong said Reds defense system is really low, I have a feeling so is the rest of L.A.W (Blue and Yellow). So they forgot to check his pockets, and somehow, with a smoke bomb, and some, "fake human parts" he escaped, as he was running he notices his old bosses ship. (Scratch) He decides to come over there, Scratch helps him, but under one condition. He needs to hide himself, how does he do that? He makes these masks called "Maskiis". Do you know how Spys (from TF2) watch, when he presses a button, he disappears? It's like that, but instead of making the person disappear, it changes their skin color, making it any type of color they want. It might even give the user a tail, antenna to blend in.
