Yokuba is Porky's closest soldier, being a general in the army. Despite this, he is better known as the tongue of the army, just as Elder Porky is the brain and the Masked Man the body. As the army's spokesperson, he is normally the one who gives speeches, sells Happy Boxes, and spreads the ideals of the Pig Masks. In public, most people know him by his alias "Fassad, the Suspicious Peddler". He is actually a major force behind the scenes. It is due to him that greed became instilled into the Nowhere Islands, which would begin Porky's Capitalist reign later.
While in public, he keeps a false front and makes himself seem cheery, friendly, and peaceful. Though, as witnessed in further events, he's actually cruel and merciless toward animals and is very bossy towards his own men...particularly if they are screwing up. He is known to be VERY nice however to his pet mouse.
Yokuba's history prior to Porky's uprising is very shrouded, but we do know he is actually Locria, meaning he is a master of PSI and is actually genderless. Why he is working against the Magypsies is currently unknown. It is clear that he shuns this past life and dislikes bringing it up. He is powerful even without his PSI, but he is not above using it.
It is believed that he openly embraces the future Porky believes in, one full of technological advances: What backs this up is due to his refusal to use PSI until his final battle.
