Mongo
MajorThis pint-sized terror fluffs with pink feathers, beady eyes gleaming with primal mischief as his serpentine tail whips. He perches like a feathered fiend, tiny teeth snapping with outsized ferocity. There's an infectious wild energy to him, a pocket predator begging to be unleashed.
Mongo begins in Book 1 as a hostile Level 1 velociraptor chick that aggressively attacks Carl and Donut before bonding as a loyal party member after training and combat. Across subsequent books he undergoes dramatic physical growth—from mastiff-sized with electric fang caps in Book 2, to pony-tall with devastating claws in Book 3, and eventually a truck-bed-spanning winged dinosaur by Book 8—while receiving upgrades like fang caps and clockwork duplicates that amplify his combat prowess. His role evolves from excitable juvenile sidekick to a powerful, expressive mount and battle ally whose joyful ferocity becomes a core part of the crawler team’s identity.
Physical Description
Mongo is a 7-inch tall juvenile velociraptor-like dinosaur with soft pink downy feathers covering his small, agile frame. He has two tiny forearms, a long serpentine tail, and a beaked mouth lined with sharp tiny teeth. His beady reptilian eyes dart alertly, occasionally sporting a small bow tie, exuding playful ferocity in every perch and pounce. A mastiff-sized velociraptor with a strong agile build stands covered in vibrant pink-hued deep-red and multicolored feathers that are long and thick along his small arms and extended tail. The skin around his eyes shows a distinct bluish tone above a widened powerful beak now fitted with golden fang caps that send out sparking tendrils of electricity with every chomp. A black magical collar circles his neck as this fierce energetic dinosaur leaps twenty feet through the air feet-first to disembowel enemies with sharp rear claws or chews on foes with practiced predatory glee while grunting and chomping excitedly. A huge feathered dinosaur standing pony tall and stretching a full 13 feet from the tip of his sharp beak to the end of his vibrant red and blue tail, over half of which is the long feathered tail itself. His back is ridged beneath dense colorful plumage, his feet end in massive claws larger than his entire juvenile body once was, and he possesses a powerful, athletic build that lets him sprint like a cheetah and unleash devastating jump attacks while remaining loyal and expressive with his dinosaur features. Small velociraptor-like dinosaur pet, scaly, agile Mongo is a large feathered dinosaur with broad wings and a long tail covered in feathers that stretches the full length of a truck bed. He frequently rolls onto his back with wings spread, allowing access to the soft undersides for scratching, and displays an excitable nature by flapping vigorously in tight spaces.
