CanonThere are two forms of storytelling mentioned: mythology and (probably embellished)historical events. Zarkon tells Honerva the story of Kaltor, which he explicitly states is mythology. Dayak instructs Hunk on the historical account of how the warring tribes of Daibazaal became one. The Archivist speaks in detail of the rulers past and some have titles like Vrigg the Great which sounds like a mix between history and mythology. HeadcanonThe people of Daibazaal enjoyed the pastime of verbal storytelling as well as movies/tv shows about their glorious King, Paladins of Voltron, conquerors of the past and perhaps even the encouragement of expanding relationships with aliens. However, once their planet was destroyed and the Empire was established, a lot of those records were lost with time or destroyed. Families passed the stories down verbally, but children were told never to speak of them in public. Written records of peace time were forbidden with the penalty of death. Zarkon squelched any stories involving friendly relations with other planets and the legends of the Paladins of Voltron. Notice that none of the Empire-affiliated Galra speak of wanting to be like their heroes in mythology. This is a staple of warrior and tribal races in sci-fi. The Klingons constantly mention their ancestors, but this is surprisingly lost in the Galra Empire. Zarkon has been on the throne for so long that his accounts of conquering became myth, history AND present news. 10,000 years is more than enough time to wipe out the myths and stories of Daibazaal from the people's memories.The approved media in the Capital is highly steeped in propaganda. These stories bathe the Empire in a radiant light. They have soap operas, romance and action stories seeded with messages promoting how to be a proper Galra. These are highly regulated and differing opinions are prohibited.However, in Morvok, Varkon, Sal and the Warden's case, being away from the Capital and cultural pressure allows them to choose what they want to watch and participate in. Varkon had little trouble loving the paladins' show as much as he loves Zarkon.

The amazing user GenerationWest on Youtube took it upon themselves to make an hour long compilation of nearly every voice from Season 1-8. It even includes background Galra with one or two speaking lines. 

Full compilation

They also created one for video for each Season.

After S8, there will be more reference drawings. The S8 trailer showed us some new weapons, including a Galra broadsword that we’ve never seen before!

Hi! Here are some resources for you to achieve your goal of learning about his personality!

Kolivan Pics

Voltron Reference has a good set of Kolivan pics. There is also a user named bentfire who posts screenshots from all the seasons if you’re looking for a particular episode.

Kolivan dialog 

Springfield! Springfield! UK is an excellent resource for this. They have all the dialog per episode up to Season 6.

A lot of the names are made up. However, there are a few that use real names. Ranveig, Janka, and Bogh(surname for a crew member) are a few examples and each hails from different countries. Out of respect for other cultures, I would steer clear of using real names. Here are some naming patterns that can help you make up your own names! 

Here is the full list of Galra names given up to S7. Try mixing and matching parts of each name until you find one you like. Just be sure to google it or you might unintentionally end up with a buff warlord named Ranveig. Apparently, Ranveig is a variant spelling of Rannveig, a cute girl’s name of Norse origin. :) If this was intentional, much applaud to the designers!

Hi there! Yes, suggestion posts are welcome! Their body proportions are easy to miss or dismiss as an art style.  I can show you many examples where I messed up on this. XD But when up against humans, it is very clear. Their legs, torsos, arms, and neck lengths can vary, but they are always elongated. Good idea! I may elaborate on this in detail sometime in the future.

 @yumirei also wrote a good post showing the differences between Galra and Humans. Do check it out!

Thank you! Sept & Oct are going to be extra busy due to art class, but I am hoping it will improve my content here. Also, I’m really hoping S8 gives us some more Galra content, but if the series ends without answers to the questions, I will start sharing more headcanons to fill in the gaps! Thanks for your support.

Thank you so much, anon. That means a lot. Thank you for your support too!
