By the movies, Peter Parker and Angelica Jones are walking by a sign about a
movie called "Dinosaur Destroyer". Peter says that that movie is getting a
fortune in free publicity thanks to that creep, Kraven the Hunter – he's on
safari in the Savage Land right now, hunting live dinosaurs. Just then, they
notice a few thugs robbing the cashier. They run into an alley and change to
Spider-Man and Firestar. Firestar uses her powers to stop the robbers'
bikes, and the robbers run the other way. Spider-Man uses his web to make a
huge dinosaur statue move, scaring the robbers. Firestar adds flames to the
show, and the robbers change direction again, running straight into police
officers. The officers arrest the robbers, and the superheroes take off
through the sky.

Flying and webbing through the sky of New York City, Firestar asks
Spider-Man about the live dinosaurs he said Kraven the Hunter was hunting.
Spider-Man explains that they still exist in the Savage Land – a remote lost
world that Kraven discovered, and where he is right now.

In the Savage Land, Kraven's camp already has two caved prehistoric
creatures. Kraven drinks a potion to give him strength, and leaves for
another hunting trip with his assistant, Skelton. Skelton lays meat in the
jungle as bait, and when the dinosaur arrives, Kraven jumps at him from a
tree and knocks him down. The dinosaur tries to struggle, but Kraven knocks
him out with sleeping gas. Kraven then tosses the dinosaur into a cage, and
Skelton says that that makes all three prehistoric creatures. Kraven answers
that they're building to the greatest capture of all – New York itself!
Soon, his growth energizer will hatch his dinosaur eggs, and he'll get a
destructive dinosaur army – New York will surrender itself to him. But
first, to make the energizer work, he'll need the Eye of India ruby and the
most powerful living heat source on Earth – and her name is Firestar.

Back in New York, Firestar is flying in the sky. Iceman is ice-sliding below
her on the road. Kraven and Skelton are in a truck not far away, watching
Firestar. Skelton drives straight into a pole, and a cage falls from the
back of the truck. The cage breaks, and a flying dinosaur flies out to the
air. Firestar realizes that Spidey was right – prehistoric animals do still
exist – and this one is coming after her. The dinosaur chases Firestar
through the sky.

Iceman slides to the back of the truck, and is shocked by what he sees
inside. Meanwhile, the dinosaur almost catches Firestar, but she gets free
with her powers, and brings the dinosaur back down to the cage, re-trapping
it. Kraven the Hunter tells her that that was fantastic, and she thanks him.
He introduces himself, and she tells him he's even more handsome in person
than on his poster. He asks her to be his guest at the museum tomorrow when
he unveils his prehistoric animals, and she accepts. He carries the cage
back to the truck on his bare hands, gets in and drives away. Iceman is
surprised that Firestar really bought that guy's phony charm, but she
doesn't think it's phony.

In Peter and Bobby's room, Angelica tells the boys and Aunt May that Kraven
seems like a nice guy. Bobby says he smells like a zoo, but Angelica says
that at lest he doesn't live in one and leaves the room. Aunt May, cleaning
the fireplace, says that she'll have it clean soon. Peter sees that she is
about to move the statue that turns their room into a lab, and yells
"don't!" He's too late, though, as all the furniture changes. Still, he
manages to distract his aunt and move the statue back, switching the lab
back into a bedroom. He covers for it by telling her they'll finish cleaning
themselves. She thanks him and leaves, but not before making a comment to
Bobby about his rent. Bobby asks Peter to lend some money, but Peter
refuses, saying he needs the money for chemicals to make more web fluid.
Peter turns the room back to a lab and says that with Kraven around,
Angelica is gonna need a couple of chaperones.

In the museum, Kraven is onstage, speaking to the audience, which includes
Bobby, Angelica and Peter. Bobby yawns, and Angelica tells the boys they're
just jealous – maybe because Kraven is so tall, so muscular… Peter adds "and
so twisted", and says everyone with such an obsession to hunting is
dangerous. Kraven unveils his three dinosaurs to the audience, and Angelica
thinks it's magnificent. Suddenly, one dinosaur breaks his cage, and the
audience flees. The superheroes hurry to change to their costumes. The other
two prehistoric creatures break loose too, and the flying one throws
Firestar into a wall. The mammoth throws Spider-Man too, and Iceman freezes
it, but it breaks the ice easily.

In a nearby room, a policeman tells another policeman that he doesn't care
what's happening out there – their orders were to guard the Eye of India no
matter what. They both run away, though, once the dinosaur enters and chases
them. The room now clear, Skelton hurries to steal the ruby.

Firestar tells Spider-Man to use the hose next to him to flood the room, and
after he does, she heats the water until they boil under the mammoth's legs.
She then notices Kraven leaving, and wonders where he's going when he should
be helping out. She flies after him, and Ms. Lion follows her.

Firestar finds Kraven in the street, talking to Skelton. Skelton gives
Kraven the Eye of India, and Kraven tells him good job – only this perfect
ruby can create the laser beam to power the growth energizer – with
Firestar's special energy power in the ruby, they'll hatch the dinosaur eggs
and Kraven will control a dinosaur army and capture New York. Firestar sees
Kraven's true nature and realizes she was wrong about him.

In the museum, Iceman encases the flying dinosaur in a block of ice and
Spider-Man traps the walking dinosaur in his web.

Firestar reveals herself to Kraven, and Kraven orders Skelton to get him a
net. Skelton goes to get it, but Firestar heats the ground under his feet.
Ms. Lion chases Kraven, and Kraven climbs a wall to a rooftop, holding a
shield. Firestar attacks with flames, but Kraven protects himself with the
shield. He than manages to tie her up, but she burns the rope. He next tries
a heat-sensing boomerang that shoots freezing spray, and this time it works
– Firestar falls to the ground.

Kraven jumps from the roof, catches Firestar in the air with one hand,
swings on a tree branch with the other hand, and lands on his feet. He then
puts the unconscious Firestar in the truck and tells Skelton that this hunt
has ended. They drive away, and Ms. Lion hurries to tell the boys.

Iceman and Spider-Man has put the prehistoric animals back in their cages.
Peter says someone wanted the animals to escape – the cages were sabotaged.
Bobby says that they must have done it to steal the ruby in the confusion.
Ms. Lion runs in, barking, and Bobby realizes she wants them to follow her.

In the truck, Kraven tells Skelton that they can't have Firestar's friends
tracking them down too soon. He presses a button, and an orange liquid
starts pouring after the truck, covering their scent.

Spider-Man and Iceman follow Ms. Lion through the streets, but Ms. Lion
stops when she gets to the orange liquid – the scent is gone. She takes off
a different direction, and the two superheroes follow.

Firestar wakes up in a place resembling the prehistoric era. Kraven welcomes
her to his lair – here he perfects his hunting skills to survive in the
Savage Land. It is built to max his abilities. Kraven tells Skelton to
demonstrate, and Skelton presses buttons in the control room, activating
various death traps – a pit, a volcano and an avalanche. Kraven asks
Firestar is she's impressed, and she says she's not. She gets up and traps
him in a cage of flames, but he escapes, saying he's got the swift of a
cheetah. She answers that even cheetahs get caught, and flies after him. He
leads her to a trap, where Skelton activates cold air again. Firestar
freezes and falls, but Kraven catches her.

Ms. Lion leads the boys to a building and they enter, but it turns out she
just came for food. Bobby says she must have lost the scent. Peter sees a
cover story about Kraven – he's standing next to a famous old plane. And
Peter knows just where that plane is kept.

Firestar next wakes up in a cage. She tries melting it, but it activates
cold air again. Kraven tells her she cannot escape from there. He shows her
his growth energizer and the eggs he brought back from the Savage Land and
says that only her special energy can focus through the Eye of India and
hatch his dinosaur army. She says he's as crazy as his plan if he thinks
she'll cooperate, but he says she will, because if she doesn't, her friends
will suffer once they get there with her as the bait.

Spider-Man and Iceman get to the old hangar, and Peter's spider-sense is
registering danger. Ms. Lion barks at the door, and Bobby freezes it and
breaks it. The superheroes and the dog walk in.

In the control room, Skelton spots Spider-Man and Iceman through the
security cameras. He tells Kraven, and Kraven says that when he faces his
prey his jungle powers will be at their peak. He drinks the same power drink
he drank before and smashes a boulder.

Bobby and Peter enter, led by Ms. Lion, and see Firestar in her cage. She
tells them to be careful – it's a trap. Kraven arrives and confirms that,
ready to battle. Ms Lion attacks, but a hidden net-trap catches her on the
way. Kraven empties the net into a cage, trapping the dog. Skelton activates
an avalanche above the superheroes, but Iceman creates a huge ice shield to
block the boulders. Spider-Man tells him that snow won't last forever and
climbs the cliff, destroying the avalanche machine with a boulder. Iceman
creates an ice ladder to Firestar's cage and climbs it, but Skelton
activates the volcano below them and the ladder melts. Bobby almost falls
into the volcano, but Peter rescues him, spinning on his web. An electric
net falls on the two superheroes and zaps them, and they faint. Kraven
laughs with pleasure – he made another capture.

Shortly later, the three superheroes' cages are hanging in the air. Kraven
has a remote control that allows him to electrocute Spider-Man and drop
Iceman into the volcano. Firestar has no choice, and Kraven releases her,
ordering her to channel her hottest beam through the Eye of India – the
growth energizer will do the rest. Firestar does as ordered, and the growth
energizer sends a beam at one of the dinosaur eggs. Within seconds, the egg
hatches and the dinosaur inside grows rapidly to a huge size.

Peter tells Bobby that this is their chance to move, since Kraven isn't
watching, but Bobby is still too close to the volcano – he can't ice up.
Peter starts swinging Bobby's cage to get him far from the volcano, but then
Kraven notices them and presses a button, dropping Bobby's cage. Still,
Bobby manages to jump out in the last second and transform into Iceman,
landing on an ice-slide. He then freezes the top of Peter's cage,
short-circuiting it, and Peter can open the bars and jump out. Firestar
shows them the huge tyrannosaurus rex that hatched from the egg. The
dinosaur attacks and the superheroes hurry to start battling it. It breaks
Iceman's ice-slide with its tail, making Bobby fall from the air onto the
side of the volcano. Skelton activates the volcano, and lava starts nearing
Iceman. Firestar creates a huge fire-shield and saves Iceman. The
tyrannosaurus prepares to stomp and crush Ms. Lion, but Spider-Man distracts
it by pulling its tail. In front of his amazed friends, Spider-Man gets
tosses into the dinosaur's mouth. Still, he manages to open the dinosaur's
mouth with his strength. Iceman ices the ground under the dinosaur, and
Peter swings out of its mouth. With his ice, Bobby leads the dinosaur to
above the deep pit, and then Firestar melts the ground, making the dinosaur
fall in.

Iceman freezes Skelton's controls and handcuffs him with ice. Kraven tackles
Spider-Man and tells him that soon they'll all be exhibits in his private
zoo, but Peter tosses him into the water pit with the dinosaur. Kraven begs
for his life, saying he'll do anything, and Bobby asks him if he'll lend him
fifty dollars for the rent. Firestar reverses the growth energizer and makes
the dinosaur small again, and Iceman fishes it with an ice spoon.

Later, all the dinosaurs are put on a plane to take them back to the Savage
Land where they belong, and Kraven the Hunter and his assistant Skelton are
put behind prison bars, where they belong. Bobby gives Aunt May his rent and
apologizes for being late, but she tells him he forgot he already paid it –
Angelica and Peter gave her his envelope when they paid their rent.
