Escape from the Erupting Underwater Volcano!!
The narrator reveals that there has been a sudden major Earthquake causing damage to a city in Australia, but the quake was actually caused by Turtlar and his Seacons, who were blasting parts of the sea bed in preparing the land for a new Decepticon base to set up. They've now accidentally activated an underwater volcano and Giga isn't happy as it means the Autobot will probably come and check it out, and they may find the new base.
Lightfoot is already on his way to Australia and as he arrives he lets the other Autobots in Japan know that he has found out where the
epicentre is, about 100km offshore from Sydney, and that he's now going to go underwater to get a better look.
Soon enough, he finds the underwater volcano and sees that it was the cause of the earthquake earlier. He reports this back to base and says that it will likely erupt within 24 hours but he doesn't know when exactly so he'll try and gather some precise data for them. As he starts to do this though he has to move as a barrage of missiles fly at him!
It's the work of the Seacons, who have arrived in full force and start to chase after Lightfoot. As he swims off he sees a strange structure ahead of him and then realises that it must be a new Decepticon base they are creating, but before he can get any closer the Seacons blast him and then start to circle him at incredibly quick speeds.
They then all start to shoot lasers at both him and the ground, causing the latter to open and making Lightfoot fall down a crevice. The other Autobots try to contact him but don't get a response, so Ginrai says they will move out and after the Headmaster Jrs load their Transtectors into God Bomber, Super Ginrai blasts off and carries his power up out whilst having the wings stuck onto his back so he can fly faster.
When Turtlar reports, Giga just wants him to go and kill Lightfoot immediately as he knows the location of where their new base is, but Mega suggests that they should wait for now as it is likely that Lightfoot has already contacted the other Autobots and now they will be on their way to rescue him. So instead, they should wait for them to arrive and then kill them all at once. Giga likes this plan and since the Seacon's specialty is at underwater combat, it should be no trouble for them to do this.
And as the other Autobots arrive, Super Ginrai tells the others to go and help out the people effected by the earthquake earlier in any way they can, as he leaps down into the sea and leaves God Bomber behind. He begins to swim to the location where Lightfoot last reported in at, but doesn't notice that Gilmer and Turtlar are also nearby. Super Ginrai swims down the crevice and finds his friend pinned under a large rock.
As he removes the rock, Lightfoot tells him that he found a new Decepticon base in the area and that the earlier earthquake must have been caused by Decepticon construction. Before he can go on any further though, they both look up to see lots of large rocks heading towards them, which is the work of
Learning from Gilmer that Super Ginrai is now stuck with Lightfoot, the Decepticons all start laughing at the fact that when the volcano blows, it will destroy the two Autobots with it. As they are still trapped, King Poseidon seals off the crevice so they definitely cannot get out as back on land the Headmaster Jrs head back to God Bomber, who shakes his head when they ask if Ginrai and Lightfoot have returned yet.
The three of them merge and transform as they all want to go and see what is taking Ginrai so long, but God Bomber stands in their way and then picks up and drops Shūta and Cab and as they yell at him for being a jerk, he tries to communicate that he will go and find Ginrai whilst they stay here. Minerva understands this and lets him head off into the ocean.
As he jumps down, King Poseidon spots him and start to chase after the Autobot, but then the volcano starts to erupt and embarrassingly for the Decepticons, the chunks of rock in spews out not only destroy several other Seacons, but also slam into parts of the base. As Lightfoot realises what is happening, he suddenly suggests that they only have one option left: he will self destruct to destroy part of the wall and let Super Ginrai escape.
Super Ginrai has to take drastic action to stop him from going off and doing this and tells him not to do something so stupid yet as they still have time to get out of here. Outside, King Poseidon is trying to shoot down as many rocks as possible but there are too many and soon he is knocked out of the way, leaving the rest of the rocks to collide with the new base and destroy it. God Bomber meanwhile makes his way to the rock wall and after using his power to break it he sees Super Ginrai and Lightfoot.
As the three of them get back out, they see that King Poseidon and a small group of Seacons have also survived, so Lightfoot says he will deal with the units whilst Ginrai fights the gestalt. Super Ginrai changes into God Ginrai and starts to battle the Decepticon giant but thanks to some sneakery he gets himself into a headlock and is pushed towards the volcano with King Poseidon's goal being to push him into the lava below.
Lightfoot destroys the remaining Seacons and then sees that God Ginrai is in trouble, so he uses Chokon power to spin himself so quickly that King Poseidon is distracted, giving God Ginrai the chance to break free from him and then throw him towards the lava. Instead of letting him die though he changes his God Cannon with Chokon power and fires, blowing the gestalt apart.
Later on Giga yells at Turtlar for his failure, but Mega says that it isn't his fault as they have all underestimated the power of God Bomber, which starts off their next plot to do something about Super Ginrai's new power up. Meanwhile the Autobots have been victorious once again thanks to God Bomber's help as Super Ginrai is seen flying back with him to the Autobot base.
God Bomber cannot speak, and more is revealed about him and his relationship to Ginrai later on in the series.
