In no time, behind the Tyrannosaurus appeared a silver Triceratops, and a red Pterodactyl began to fly over them.

When the three of them were totally inside the tunnel, the two groups began to advance towards each other with the clear intention of fighting.

Before clashing, both the three-numbered yellow and the four-numbered green robots suddenly took out of nowhere a pair of laser guns each and began to shoot toward the dinosaurs.

Laser beams flew towards the beasts, but the tyrannosaur reacted by dashing forward, and while its mantis arms began to glow with a dark shine, it blocked the beams with them, making the attacks disappear.

When the tyrannosaur blocked the attacks, the pterodactyl flew over it, and while nearing the machines, it opened its mouth to shoot a red laser ray.

As if mirroring the other side's movements, the one-numbered red robot suddenly materialized a red sword in his hands, which he used to block the beam of the pterodactyl.

Then, the triceratops began to charge toward the two-numbered blue robot, but the machine suddenly made appear a blue shield in front of him. The dinosaur didn't react to its enemy's movements, and it continued charging until it crashed into the blue shield and got stuck.

But as if everything was part of its plan, the beast suddenly let out a cry, and electricity began to flow out of its horns, electrocuting the blue robot, visibly damaging it, and making him release his shield.

While all of this was happening, the tyrannosaur continued blocking the two machines' shots while the red enemy was blocking the Pterodactyl attacks. But as the blue robot was temporarily stunned, the triceratops used that opportunity to release a lightning bolt toward the green machine, which failed to dodge it and got stunned too.

Seeing that the robot was vulnerable, the tyrannosaur dashed towards the machine and bit him in the neck while stabbing him in the torso with one of its blades. After being damaged that much, the green robot began to release smoke and sparks each time it tried to release itself from the tyrannosaur's grasp.

The three-numbered robot tried to help his ally by shooting the dinosaur, but the dinosaur paid him no attention even if wounds were appearing all over its body.

As his companion was suffering, the red machine decided to throw his sword toward the tyrannosaur, managing to hurt its leg even if it tried to dodge the attack. By doing this, the green robot managed to break free from the beast's grasp.

Suddenly, the four machines began to retreat toward their entrance at high speed. Seeing this, the dinosaurs tried to follow them while shooting, but when the robots were about to leave the tunnel, four voices were suddenly heard.

"Megarobot, activate!" said the four voices at the same time.

At that moment, the voices said that the robots began to shine with great intensity.

The blue robot fused his shield with its torso, creating armor for him while his head hid inside his neck.

Both the yellow and green machines split into two pieces each, and while the green pieces fused with the blue robot's arms, the yellow pieces fused with his legs. Also, their guns fused themselves to create two canons that fit on the blue's shoulders.

The red machine dismantled itself almost completely, and while his head and some other pieces fused with the blue robot's head to create a knight's helmet, the rest of the red robot spread over the body, creating more armor pieces on the limbs.

Like this, a giant robot was formed by fusing the four other machines. Suddenly, the sword of the red unit appeared again in the giant robot's hands, but this time it was much bigger and it had the colors of the other three on its blade.

Without wasting even a second, the robot made a 180-degree turn and began to dash toward the dinosaurs. The canons on his shoulders started firing at the pterodactyl, forcing it to evade continuously and making it difficult for it to attack effectively.

As they had the numerical advantage, both the tyrannosaur and the triceratops tried to attack the robot at the same time, one on the right and one on the left.

Without stopping, even for a second, the robot stabbed with his sword toward the tyrannosaur, which clashed with him with its claws, which began to glow with a dark shine.

At the same time, the triceratops tried to ram toward the robot from the left side, but the machine reacted by stopping it by kicking it. When they crashed, electricity was released from the dinosaur's horns, but a blue energy shield suddenly covered the robot's limb, protecting him completely from any damage.

Suddenly, the canons of the robot changed the target and began to shoot at the tyrannosaur's head, which tried to dodge, but by doing that it released its grasp on the robot's sword, so he used that opportunity to quickly stab the beast in the torso, and this time it didn't manage to protect itself.

The robot's sword went through the dinosaur, which died in less than five seconds, during which the canons began to shoot again toward the pterodactyl, so it couldn't do anything.

As the dinosaurs loosed one of their members, the balance of the battle was completely broken. Without the tyrannosaur to put pressure on the robot and the pterodactyl neutralized by the cannons, the triceratops was beaten in a few seconds by the robot, before the last one of the beasts was finally shot down by the shoulder canons.

Like this, the robots emerged victorious from the fight against the dinosaurs.
