The ''cons get the key back, and return to Cybertron.
Galvatron has a giant engine built on Cybertron to move it
close to Earth''s sun. He then uses Cybertron''s plasma
chamber to attempt to drive the Earth''s sun nova and capture
the energy. Optimus Prime arrives on Nebulos after a
conference with Alpha Trion, and the Autobots pursue, except
for pacifist Cerebros and Spike who stay behind. Cerebros is
convinced by Spike to help rebuild an old Hive city ,
defended by drones (Gasket and Grommet). As the Autobots are
threatened with defeat on Cybertron, the city arrives
(flying through space), with Spike and Cerebros. Spike
becomes Cerebros''head, and in turn, Cerebros becomes the
head of the transformed city, now Fortress Maximus who
defeats Scorponok. Spike and the Nebulons use the giant
engine to suck the surplus off of the Sun before it novas,
and uses the energy to bring about a Golden Age on
Cybertron. Scorponok and the ''cons flee off into space.
霸天虎又抢回了钥匙,并且返回了塞伯特恩。惊破天在塞伯特恩
上建立一个巨大的发动机,用来把塞伯特恩推向地球的太阳。他接着
利用塞伯特恩的等离子室企图促使地球的太阳变成新星并从中吸取能
量。擎天柱在和泰师傅会谈之后抵达那布罗斯行星。汽车人们追踪霸
天虎而去,只用和平主义者 Cerebros 和斯派克留下。斯派克说服了
Cerebros 帮他改造一座的旧 Hive 城堡(由 drones (Gasket 和
Grommet) 守卫)。正当汽车人们在塞伯特恩上面临失败的困境时,
那座城堡(飞越时空)与斯派克和 Cerebros 一起来了。斯派克变成
了 Cerebros 的头部,而接下来,Cerebros 变成了那座变形城堡的
头部。那座城堡现在叫 Fortress Maximus ,他打败了 Scorponok 。
斯派克和那布罗斯星人用那个巨大的发动机在太阳变成新星之前吸取
了太阳的过剩能量,并且用这些能量使塞伯特恩进入了一个黄金时代
。而 Scorponok 和霸天虎们则逃亡在宇宙中。
------------------------------------------------------------
Scorponok graps Arcee as she has the key in her possession
and then Scorponok takes off with the Decepticons to
Cybertron. The Autobots decide to quickly follow them to
prevent Galvatron from using the key. Spike and Cerebros
stay behind to see if they can come up with something
against Scorponok. Meanwhile Cybertron is in Galvatrons
hands and he builds huge engines on Cybertron so he can move
it to Earth. Galvatron grudgingly agrees to cooperate with
Zarak as Zarak has the key in his possession. When On
Nebulos Spike and Cerebros rebuild the City Cerebros found
to a new super robot: Fortress Maximus. When the Shuttle
with the Autobots arrive on Cybertron Ultra Magnus tells
them what has happened here. Galvatron is planning to
activate the plasma energy chamber so he can destroy Earth.
De Nebulons want to destroy the key so that they can safe
the universe even though Optimus Prime tells them not do
destroy it. When the Autobots follow them into Scorponok
they are captured. Galvatron activates the Chamber with a
ten minute delay so he can safely flee. Then Fortress
Maximus arrives and attacks the Decepticons. Scorponok and
Fortress both change into their robot forms and attack
eachother. Of course Fortress wins the fight. Cerebros and
Spike then hurry to rescue the Autobots and Daniel. He finds
the captured Autobots first. Optimus Prime tells him he has
to quickly close the chamber, but Spike wants to rescue
Daniel first. The chamber is opened and the Autobots all
suffer from a power overload. Spike rescues Arcee and Daniel
just in time and flee from Scorponok. Prime then tells Spike
he is their only hope. Spike thinks of a way to send the
Plasma Energy that is send to the sun directly to Vector
Sigma. This works and the Golden Age is returned to
Cybertron by this energy. Cerebros and the other Headmasters
then return to Nebulos to destroy the remaining Hive
machines and remain there is its guardians. On board
Scorponok Galvatron and Zarak at last have control back over
Scorponok after it was hit by Plasma Energy on Cybertron.
And Galvatrons talks, as ever, over conquering the universe.
Scorponok 抓住了阿尔茜因为她拿着那把钥匙,然后 Scorponok
起飞和霸天虎们一起前往塞伯特恩。汽车人们决定立刻跟踪他们以防
惊破天使用那把钥匙。斯派克和 Cerebros 留了下来,打算找到什么
可以遏制 Scorponok 的东西。此时,塞伯特恩正在惊破天的掌握之
中,他在塞伯特恩上建立了一个巨大的发动机,这样他就可以把塞伯
特恩推向地球。惊破天并不情愿地同意和 Zarak 合作,因为 Zarak
拥有那把钥匙。这时,在那布罗斯行星上,斯派克和 Cerebros 正在
把那个 Cerebros 发现的城堡改造成一个新的超级机器人——
Fortress Maximus 。当汽车人们乘飞船到达塞伯特恩时,通天晓告诉
了他们这里所发生的事情。惊破天正打算启动等离子能量室,这样他
就可以毁灭地球。即使擎天柱说不能破坏那把钥匙,可正义一方的那
布罗斯星人为了宇宙的安全,还是打算这么做。当汽车人跟着他们潜
入 Scorponok 时被俘虏了。惊破天启动了能量室,不过为了他自己可
以安全撤离,他设置了十分钟的延时。这时 Fortress Maximus 到达
了,并且向霸天虎进攻。Scorponok 和 Fortress 都变形成机器人模
式开打。当然,Fortress 赢得了胜利。Cerebros 和斯派克于是立刻
前去营救汽车人和丹尼尔。他首先找到了被俘的汽车人。擎天柱告诉
他,他必须立刻关闭能量室,但是斯派克想先救丹尼尔。能量室终于
启动了,而且汽车人全都因此引起能量过载。斯派克及时从 Scorponok
中救出了阿尔茜和丹尼尔。擎天柱此时对斯派克说他是汽车人唯一的
希望。斯派克想出了一个办法,可以把现在正直接冲向太阳的等离子
能量束转向魔力神球。他成功了,而且依靠这些能量,塞伯特恩迎来
了一个黄金时代。后来,Cerebros 和其他头领战士返回了那布罗斯行
星去消灭了剩下的 Hive 的机器,并且留在那里作为那里的卫士。尽
管 Scorponok 在塞伯特恩上被等离子能量所击中,乘坐在 Scorponok
里的惊破天和 Zarak 终于还是重新控制了 Scorponok 。此后惊破天
还在口出狂言,像以前一样,还是那些征服宇宙之类的话。
