Obsidian Convoy
was just an average fighter, but as with all Convoys, Obsidian
became Optimus Prime. Prime was given the Matrix after the
last Prime died though unknown causes, though some think he
was killed by the recently awoken Megatron.
Here is Prime taking the back way into a Decepticon stronghold,
for every good leader knows: lead by example. The sewers
can be a dark place indeed.
