Zyudenryu Parasagun is one of the five original Zyudenryu (Guardian Beast mecha) from the Japanese series Zyuden Sentai Kyoryuger (2013). Modeled after a Parasaurolophus, it is the partner mecha of Kyoryu Black (Nobuharu Udo). In the US adaptation Power Rangers Dino Charge / Dino Super Charge (2015–2016) it appeared as the "Para Zord", piloted by the Dino Charge Black Ranger (Chase Randall). Its name is a pun on "Parasaurolophus" and "gun", reflecting its role as a ranged/artillery mecha.

On screen the Zyudenryu perform the Kamitsuki Gattai ("Biting Combination"): the mecha clamp their jaws onto the shoulders of the main robot. Parasagun forms one of Kyoryuzin's arms, with the Parasaurolophus head-crest serving as a cannon that gives it a ranged-attack function. Because Kyoryuzin's arms are interchangeable, swapping in different Zyudenryu produces several differently named formations; in the "Kyoryuzin Western" configuration Parasagun typically supplies the gun arm. It can also be combined with the other Zyudenryu.

The DX toy was released in 2013 by Bandai Japan as "Zyudenryu Series 02 Parasagun". It is made mostly of plastic and converts from dinosaur mode into the arm/weapon mode used to build Kyoryuzin, docking onto the compatible Zyudenryu toys via the biting mechanism. It includes its matching Zyudenchi ("Beast Battery" No. 02) — a battery-shaped collectible token that interacts with the DX toys and the Gaburevolver. For the US market, Bandai America released the counterpart from 2015 as the "Para Zord" within the Dino Charge line (the Power Rangers license only moved to Hasbro in 2019, so this figure predates that change).
