Sera helps Sonic up, and the hedgehog thanks the fox and praises him for
his clever plan. Just then they hear a crash, and see that something has
hit in the ice bridge above them. Tails first thinks that it's Eggman's
ship which got stuck there, but Sera screams that this it belongs to her
father. In the burning ship they see the president and Ojisan, but they
obviously can't break the glass of the cockpit to get out.
Immediately Sonic orders Tails to carry him to the ship, before its
occupants suffocate or burn to death. The fox takes off at once, but is
stopped by Metalla, who is still alive and kicking. Sonic shouts at the
robot, asking if it still hasn't got enough and to just leave them alone.
Tails wants to try his tracking device again, but it is blasted to bits by
a well-aimed shot from Eggman. The doctor congratulates the fox for his
wits, but also tells him that now their end has come. Then he commands
Metalla to attack and finish the hedgehog once and for all.
Again a wild chase begins between Sonic and Metalla, during which Sonic
lands on Knuckles head (which he accidentally stuck out of the ground when
Sonic was passing by), causing a large swelling, and Knuckles gives Sonic
a 'thumb down' for it. At the end Sonic throws Metalla directly at the
cockpit of the president's ship, which finally breaks the glass. A few
seconds later, the ship explodes.
Everything seems lost, but then Metalla appears in the smoke, carrying the
president and Ojisan to safety. Sonic can't believe it. But right after
Metalla has dropped the two (the owl landing on Tails and the overweight
president on Knuckles), a large piece of the exploded ship hits the robot
and Metalla falls down into a deep crater. Sonic jumps right after him,
but the heat prevents him to get any closer. Metalla slowly crawls upward
toward Sonic. Suddenly Knuckles comes digging out of one of the crater's
walls, grabs Sonic and yells at him that Metalla only wants to pull him
down into the magma, but Sonic refuses to listen. Then as Metalla is just
close enough to grab Sonic's outstretched hand, he slaps it away. As
Metalla slowly sinks into the magma, he says, "There can only be one
Sonic" (probably a reference to Sonic's earlier statement that the planet
is too small for two of them). Sonic's scream "Metalla!" echoes through
the icy grave as he sees his 'brother' dissolve, and Knuckles can hardly
hold him back.
