Voltron
Five centuries ago a coalition of planets were experiencing an economic boom like never seen before. Then the Galra Empire invaded. The king of Arus united the coalition into fighting back as a united front instead of separate entities. This worked for a while but the might of the Galra Empire was to much for them. That is until the development of Voltron piloted by five aces were able to drive back the Galra Empire.
After a century of warfare the peace returned. The coalition of planets formally united into a single governing body the Altean Protectorate. For the next four centuries the Alteans concentrated on rebuilding what was destroyed and living peacefully. Numerous Galra were abandoned in the retreat of their empire. They were given the planet Drule as their home. Overtime these Galra abandoned their previous allegiance and mated with several species across the universe, they became known as the Drule. The Drule joined the Altean Protectorate.
After a century the Altean Protectorate decided that the Galra Empire was no longer a threat. They never wanted Voltron used again as it posed to much risk to the Protectorate if it ever got into the wrong hands. They broke up Voltron & sent the five pieces flying in various directions. Their pilots were instructed to bury them & to never return.
The Galra Empire spent the following four centuries rebuilding, regrouping, & building bigger & better weapons. With an army and navy ten times the size of what they had in the initial invasion they invaded once again.
Without Voltron the Altean Protectorate who had no real army or weapons quickly fell to the Galra Empire.
