- "Puny humans! Now you shall feel the wrath of Lord Zedd!"
- ―Stag Beetle[src]
Created by Lord Zedd out of a drawing on a flyer outside the Youth Center for Stone Canyon's broomball team, the Stag Beetle was a monster that could drain opponents of their energy and use it against them. Stag Beetle could project energy bolts from his claws and pincers and shock his foes with claws. In his fight with the Rangers, he managed to completely drain Tommy of his Green Ranger powers. As he battled the other Rangers, he fired blast after blast at them, and with each blast it used up the Green Ranger power. Alpha 5 created a device called the "Green Energy Transducer" for Tommy to use against the Stag Beetle. By absorbing some of Stag Beetle's energy into the Transducer, Tommy was able to regain some of his lost powers. Afterwards, the Rangers assembled the Power Blaster and fired, causing the monster to fall over. Jason realized that the monster was not yet finished as Lord Zedd used a growth grenade to make the Stag Beetle grow. During the Zord battle, the Stag Beetle talked incessantly about using his pincers to attack the Rangers, repeatedly blasting them with green energy from his pincers and using his claws to electrocute the Thunder Megazord. He knocked the Megazord down, repeatedly kicking it, forcing the Rangers to switch to emergency power for the first time with their new zords. The Thunder Megazord chopped off Stag Beetle's pincers, greatly upsetting the monster. Stag Beetle was then defeated with the Thunder Saber.
Later, in "Ninja Quest, Part I", Stag Beetle was recreated by Finster to assist Rito Revolto, Fighting Flea, Lizzinator, and Octophantom in a mission where they successfully ambushed and destroyed the Thunder Zords.
He was later shown wandering around on Onyx.
Stag Beetle was also among the monsters present in Rita and Zedd's army in the Vica Galaxy.
- The Stag Beetle comes from what is commonly referred to as "Zyu2" footage, and was not seen in the original Zyuranger. Stag Beetle was intended to have been destroyed by the Megazord. Recently released Zyu2 footage further confirms this since the monster was seen kicking the Megazord during the fight with the Thunder Megazord and the Power Sword chopping off the pincers instead of the Thunder Saber which proves that the Megazord originally fought Stag Beetle. In addition to that footage there is also footage of Stag Beetle with Rita's original Putties instead of Zedd's Z Putties.
- The costume for Stag Beetle was recycled for Men in White as one of the aliens on Glaxxon's ship.
