Fortress

"Here it is, Master Heckyl, my secret project, Fortress! He isn't just powerful, he knows all the Megazord moves."

- Wrench describing Fortress to Heckyl and explaining the abilities that Fortess contains.

Fortress (voiced by Adam Gardiner) is a powerful cemetery-themed monster-like Megazord created by Wrench who knew to counterattack all the previous Megazord moves of the Dino Charge Rangers.

History
Fortress is introduced to Heckyl by Wrench, who explains he built Fortress and tells Heckyl about his abilities, then demonstrates his skills with a group of Vivix. Later, Heckyl brings Fortress out to Amber Beach when Lord Arcanon, Singe and Doomwing arrive on the scene.

After a small conversation, Arcanon attacks Heckyl, who transforms into Snide and orders the Magna Beam to be fired from Sledge's Ship on Fortress. Once Fortress is enlarged to continue speaking in roars, Snide enters his cockpit and attacks Arcanon and his followers, who attempt to defeat Fortress with the Dino Charge Megazord Pachy-Rex formation. When that fails, they switch to the Dino Charge Megazord Tri-Stego Formation and Ptera Charge Megazord Para-Raptor Formation, but these also fail.

The trio finally retreat, and the Rangers take back control of their Zords. During the fight, Chase remembers advice from a food critic and says they need to try something new. While Heckyl takes back control of his body, the Rangers summon the Titano Charge Megazord and hold off Fortress until Kendall arrives with plans for a new and strongest Megazord formation: the Dino Charge Ultrazord, which overpowers Fortress with it's various attacks before destroying it with the Ultra Plasma Final Blast. Although he was inside, Heckyll survived.

Personality
Fortress is a mindless robot speaking only in roars.
