Optimus Prime (Tyran)/607.26 Kappa

Optimus Prime is a character from the Transformers: The Game for consoles.

Autobot Campaign
Optimus Prime provides intelligence and missions to Bumblebee in his search for the All Spark. Eventually, the clues lead the Autobot to Sam Witwicky. After saving Sam from Barricade, Bumblebee finally completes preparations for the Autobots to arrive on Earth.

Once on Earth, and having informed the two teenagers of their mission, Prime and the Autobots are discovered by Sector 7. Optimus sends Jazz on a high-speed distraction mission, then sends Ironhide to rescue Jazz from a double-threat posed by the government agents and various Decepticon scouts.

When Bumblebee is captured, Prime transforms and chases the chopper which from which the small Autobot is tied. After a lengthy chase, Prime manages to catch the net, only to be thrown off by another Cybertronian meteor. As Bumblebee is carried away, Optimus promises he will not fail him again. Jazz informs him that the meteor is not an Autobot. Prime confronts the new threat, who turns out to be the Decepticon Triple Changer Shockwave. The two battle it out across Tranquility before Optimus finally destroys him. But not without overhearing Starscream's transmission revealing the location of the All Spark.

Optimus then returns to an intel role as he guides Bumblebee in his mission to retrieve the All Spark from Hoover Dam. Unfortunately, the Decepticons manage to free Megatron, leading to the final battle in Mission City.

As the Autobots battle it out with the Decepticons to protect Sam and the All Spark, things seem to take a turn for the worst as Megatron finally arrives. But before he can claim the cube, Optimus attacks him.

The two battle it out until Megatron is finally on the ground, seemingly devoid of life. Optimus then kneels to take the All Spark as Sam hands it to him. Megatron however awakens, leaping at Optimus with his chain-flail out, and making one last attempt at defeating his adversary. Optimus grabs the chain, pulling Megatron in closer, and with the All Spark clutched in his fist, delivers a punch through Megatron's spark. As Megatron dies, Optimus reflects on the losses and rewards of this battle, as the Autobots have a new home. Optimus plans to guard the humans in secret, "For freedom is the right of all sentient beings."

Decepticon Campaign
If played in Decepticon mode, Optimus is beaten to the ground, and as he crawls for the All Spark, Megatron smashes his head with his flail before using the cube to destroy humanity.
