Chapter 1: Before Dinosaurs
Nearly a year after Wily's latest defeat, one of Fury's closest friends opens a robosaur styled park, where they shows mechanical races of prehistoric (dinosaurs, other animals during, before and after those robosaurs), and even some of mechanical modern day animals. Then Mega Man along with other superheroes goes to the park. But, Dr. Wily's robots gained easy access thanks to the crooked operator of the park and reprogrammed the animalbots to go on a rampage. Now it's up to Mega Man with other superheroes to stop those robots, which goes on a rampage and those ones behind it. This time Mega Man doesn't only goes with other superheroes, but also with Darci Roll and as well as his two new robo assistants, Rush and Eddie. Rush is a robo-dog which can smell for example traps, while Eddie is a supportive robot, who can give navigation to Mega Man.
First Mega Man, Invisible Woman, Darci Roll, Spider-Man, Rush and Eddie goes in to a mini-marine ship, which allows them to travel underwater. After the first one Supergirl, Batman, Iron Man, Nick Fury, Captain America and Cyborg goes in to a second one. Then they travels to a underwatersea aquarium where hostile mechanical races of prehistoric and modern animals appears, jellyfishes, anomalocaris, trilobites, giant orthocone (cameroceras), sea scorpion (megalograptus), brontoscorpio, giant sea scorpion (pterygotus), sea sponges and sea urchins. However, Iron Man and Mega Man comes out to scare away those robots, which only works to few of those. Mechanical races of trilobites, giant orthocones, sea scorpions, brontoscorpions, giant sea scorpions, sea sponges and sea urchins. Mega Man and Iron Man together defeats those robots, then comes back to those mini-marine ships. Now they continues to drive those marine ships into a new part of the Underwatersea Aquarium.
When they begins to enter there some danger things will comes to be more dangerous than before. Those hero-characters in two marine ships meets dangerous mechanical races of prehistoric sea fishes such as Dunkleosteus, Hyneria and Stethacanthus. It forces Mega Man and Iron Man to go out of those marine-ships again, to confront those hostile robots. Then Mega Man and Iron Man goes back to those ships again. After going back to those ships, they goes out of those ships, during the same time Iron Man secretly controls both of those marine ships (without aknowledgement of Wily).
Then they meets a hostile mechanical race of Hynerpeton. They scares away those hostile robots in this time. When they see a mini-gate to the next part, of the park, the gate requires password with six letter stones, which then would scan those stones. All of those heroes will be in the same group to find those letter stones. Before they finds the first letter stone, Bright Man comes out from those trees to block the way from searching the first one. Cyborg talks to Bright Man.
"Bright Man, can you move on to the other side?" Cyborg asks him to do.
"No, you'll be blocked or you have to fight me" Bright Man says to him.
"Okay, I haven't another choice than to confront you, Bright Man. You others can move on" Cyborgs talks to Bright Man, and says to the others to pass away.
Cyborg confronts and quickly defeats Bright Man.
When the other passes away, they finds the first letter stone (S), while Cyborg goes back to the place near the gate.
Before those other finds the second one, Star Man comes out to block them from searching the second one.
"Star Man, can you please move on to the other side?" Batman asks him to do.
"No way, you have two choices go back to your home or come and fight me" Star Man answers back.
"Okay, I haven't another choice than to confront you, Star Man. You others can move on" Batman gives an answer to Star Man and says to the others to pass away.
Now, Batman confronts and in last also defeats Star Man.
When the other passes away, they finds the second letter stone (O), while Batman goes back to the place near the gate.
Before those other finds the third one, Gravity Man comes out to block them from searching the third one.
"Gravity Man, can you please move on to the other side?" Supergirl asks him to do.
"No way, you have two choices go back to your home or come and fight me" Gravity Man answers back.
"Okay, I haven't another choice than to confront you, Gravity Man, You others can move on" Supergirl gives an answer to Gravity Man and says to the others to pass away.
"But, we need you" as Mega Man says to Supergirl.
"Mega Man, I have to defeat that robot master alone" as Supergirl answers back to Mega Man.
Supergirl confronts and in last defeats Gravity Man.
When the other passes away, they finds the third letter stone (R), while Supergirl follows them again. Also then the others meets and defeats other robots, such as three Sniper Joes and two Metbots. Then they finds the fourth letter stone (E), and now Supergirl comes back.
"Hello I'm back" Supergirl says to everyone.
"You're welcome back" as Mega Man says back to her.
When they tries to find fith and six ones, they are eventually blocked by a Rolling Drill.
"Stop, you're not allowed to pass" the Robot says.
"Hah, can you say. Now it's showtime" Mega Man says.
Now they confronts and defeats this mini-boss (Rolling Drill). Now, they finds those two last letter stones (F and T). Before coming back to the same place, as Batman and Cyborg are placed in, they are blocked by an ED-209.
"Now, you're not allowed to pass" as this robot says.
"Okay, we understands and it's SHOWTIME" as Iron Man says.
So, they confronts and in last also defeats that robot. Then they luckily goes to the same place as Batman and Cyborg are. They tries to unlock the gate twice, but failed to do that.
"this time, we have to succeed to unlock this gate" which Mega Man says.
"Yes, I agree" which Spider-Man says.
"Cyborg, what are you doing?" as Spider-Man asks him.
"I think that I know that the paspassword is, F first, then O, then R, then E, then S and in last T" as Cyborg sees and says.
Now, the gate scanned those stones and became approved.
"Now we have to pass the gate" as Mega Man says.
Mega Man and other heroes with him passes through the gate. Now they enters a forest, where they meets mechanical races of Great or Giant Spider (Megarachne), Petrolacosaurus, Meganeura, Arthropleura, Proterogyrinus, Archaeothyris and Clepsydrops. However, those heroes scares away those robot animals, except Proterogyrinus, Meganeura and Arthropleura. Now, they confronts and in last also defeats those robots. Then they meets Stone Man.
"Stone Man, can you please move on to the other side?" as Spider-Man asks him to do.
"No, you'll be blocked or you have to fight me" as Stone Man says.
"Okay we'll have no other choice than to confront you" as Mega Man says to Stone Man.
Spider-Man and Mega Man confronts, and quickly defeats Stone Man. Now, Spider-Man and Mega Man along with other heroes with them passed through the forest, but only briefly after defeating Stone Man, they meets Dust Man.
"You're not allowed to pass through me" as Dust Man says to those heroes.
Mega Man and Spider-Man says "Now it's time for an action".
Spider-Man and Mega Man confronts and quickly defeats Dust Man. Now, Spider-Man and Mega Man along with other heroes passes through the forest to the desert-area by two safari cars. When they passes through the desert, they meets many of robotic Seymouria, Edaphosaurus and Dimetrodon. However, they're too many, so they haven't another choice than to flee from those hordes of robo-animals. But in last they escaped from those robot animals and meets Ring Man (who stands up on a stone) with laser gun in the mid desert-area. Mega Man quickly shoots down and easily defeats Ring Man.
After defeating Ring Man, they meets mechanical races of prehistoric animals such as Gorgonops, Rhinesuchus, Euchambersia and Scutosaurus. However, they easily scares away Rhinesuchus robots, then also defeats those other animal robots.
After defeating those animal robots, those heroes meets Charge Man.
"You're not allowed to pass on to the next area" says Charge Man.
"Okay, we'll not pass through this area further, but it's time for an action" as Supergirl says to Charge Man.
Those heroes confronts and in last also defeats Charge Man. Now they're passing through the desert to a new forest area, just before entering the "Age of Dinosaurs/Robosaur Park". However, briefly after they entered the forest area they meets another ED-209 robot.
"Now, you're not allowed to pass" as this robot says.
"Ok, agreed and it's SHOWTIME!!!" as Iron Man and Mega Man says, and quickly defeats this robot.
After defeating that robot, they passes through the forest with safari cars, then meeting mechanical races of Lystrosaurus, Moschorhinus, Thrinaxodon, Proterosuchus and Euparkeria. Now, those heroes confronts those animal robots, first by scaring away Euparkeria (which would move on to the Robosaur Park, without their acknowledgement). Then they defeats those other animal robots.
After defeating those robots they passes through the area until the closed gate. Immediately after the gate is closed, Skull Man just jumps out and blocks them way from entering the next Park.
"You're not allowed to pass into the next area" Skull Man says.
"Okay, but it's time for an action!!" as those superheroes (Mega Man, Invisible Woman, Darci Roll, Spider-Man, Supergirl, Batman, Iron Man, Captain America and Cyborg) says. Those superheroes confronts and lastly defeats Skull Man.
Now they enters to the next park, "Age of Dinosaurs-Park".
