Brodo is an old wizard who once was one of the most powerful wizards on Third Earth.
It is recorded that Brodo had been a powerful wizard until Mumm-Ra felt he threatened his evil dominion. Mumm-Ra tricked him and Brodo had been stuck on the Astral World ever since. Lion-O rescued Brodo, along with Jaga, from the "Astral Prison". For his gratitude, Brodo invoked the Ancient Spirits of Good and sent Lion-O back to Third Earth because he did not want the young ThunderCat's life cut short thanks to Mumm-Ra.
His name probably comes from Old Norse bróðir (“brother” or male sibling), from Proto-Germanic *brōþēr, from Proto-Indo-European *bʰréh₂tēr which is the cognate of Old English brōþor (English brother).
