When you watch Grimm Season 5 Episode 13 online, a young luchador named Goyo is bitter and angry about his constant defeats in set matches, when his whole life he wanted to be a great and respected luchador. When he's told that he doesn't have the "pizazz" to make it big, Goyo goes to his friend Benito, who makes luchador masks, and commissions a special, unique mask. Unbeknownst to Goyo, Benito makes the mask with the face he sliced off a still-living Wesen, a Balam, and then turned into a mask with a ritual. All Goyo knows is that he feels an awesome power when he puts the mask on. Benito warns him repeatedly to only wear the mask while in the ring. But it seems inevitable that the proud and stubborn hothead won't heed Benito's warnings for very long. Meanwhile, Eve continues her investigations into Black Claw, turning her focus onto Rachel Wood, the Lowen campaign manager who has recently approached Renard with an offer to join Black Claw. What will she find out? And can Team Grimm stop the young luchador Goyo before he does something stupid and it's too late? Find out when you watch Grimm Season 5 Episode 13 online!
