These are some songs that one of my friends thought were great for an anime opening if Legacy of the Primes was an Anime. This one's call Till all are one by Stan Bush.
In a cold, faraway world
A battle is raging between evil and good
From the stars, they came here to Earth
Caught in their struggle through the whole universe
Robotic warriors give it their all
Fight in disguise, till the victor stands tall
Transformers
Defenders of truth
Robots who fight in disguise
Transformers
When the battle is through
Only the strong will survive
Till all are one
Unknown soldiers fighting the war
Use the power and wisdom from those long before
Leads them on to victory
Lights their darkest hour, their one destiny
Truth has its moment and right always wins
Prepare for the fight, let the battle begin
Transformers
Defenders of truth
[Lyrics from: ]
Robots who fight in disguise
Transformers
When the battle is through
Only the strong will survive
Till all are one
Galaxy's warring foe retreats to its darkest corner
With the enemy gone, they will finally live on
As they revel in their victory
Robotic warriors give it their all
Fight in disguise, till the victor stands tall
Transformers
Defenders of truth
Robots who fight in disguise
Transformers
When the battle is through
Only the strong will survive
Transformers
Defenders of truth
Robots who fight in disguise
Transformers
When the battle is through
Only the strong will survive
Till all are one
