King Dragon strikes me as the kind of person who sounds intimidating at first, but then you realise that he’s sort of just here to be edgy. He’s never actually fought Dennis (at least from what I’ve seen of him), except for the time that he tried rapping at him, I guess.
Like the townspeople were like “Dennis, we need your help to defeat King Dragon!”
And Dennis is like “Why? Is he destroying villages, burning crops, and/or wreaking havoc upon the land?”
And the townspeople just go “No, he’s just really annoying. Can you make him go away?”
Okok so this is just a thing I was thinking about but just hear me out...
In the episode where shiro and the black lion go back to the lion's home planet we learn that it was also zarkon's, which means that there's a very high chance that each of the lions were created on different planets depending on their original paladin.
So this is going along the storyline that Keith's the new black paladin since shiro's gone,,
Ok so let's say that one night keith and lance get into a REALLY bad fight, which normally would end with the two storming off from each other, only this time the fight was about how lance wanted to return to earth. Keith brings up how lance's family is a part of the universe and if lance leaves voltron than he's almost guaranteeing their demise, to which lance finally cracks and screams at Keith for not knowing what family's like, stating something along the lines of "how would you know how I feel? You're just an orphan!". Keith obviously doesn't take this well and snaps at him some more, eventually leaving to the training deck to let off some steam. Lance realizes what he's said, and what he's done, and has had it. He's been so done with the team treating him like trash he'd finally snapped, and at this point he was over sulking in his room until the next mission, so he packs up. He grabs all his belongings, some rations to last him, and he gets in the blue lion and sneaks out.
He turns off the lions tracking system and they fly aimlessly for a bit until the lion suddenly jolts forward and goes into hyper speed, until they reach a water planet. For a moment lance has hopes that it's the earth but at a closer look he realizes it's not and continues to lay back as the lion takes him to his "destination". Another couple of minutes pass and they hit the surface of the water, quickly plunging deeper. Lance begins to freak out and does his best to stop the lion but it's no use.
Before he has a moment to process what's happening they're in an underwater cave, with at further inspection seems to be highly man-made. They finally turn a corner to be greeted with a unbelievably high tech, airtight room, where blue goes into the middle pad and shuts down, leaving lance alone. Scared and confused, he exits the lion to explore, and finds a door, or a gate. With a bit of force he opens it, to find himself in a large hallway, once again filled with water, only this time with the addition of merpeople, who seem to be just as confused as he is, just for a different reason.
One notices him by the door in his paladin armour and asks him if he is the blue paladin, and remembering his last confrontation he's hesitant. Nonetheless the merman puts two and two together and takes him to their king. The king's ecstatic that the blue lion has returned and reveals that this was the planet and colony that built the blue lion, and this was the home of the previous paladin. Lance tells the king what he had done and asks why the lion had brought him there, to which the king suddenly grows somber. He tells lance about the old paladin, and how she often has lashed out on the team, and in return became very untrusting and unstable. Due to this, to calm her down the blue lion would bring her here if she was ever in trouble of herself.
Lance takes a moment to think about the new knowledge he was given, and remembers how blue brought him here because of her instincts, and how she knew he wasn't ok even though he had not. The king then continued, stating that the paladin was far more unstable than anyone had ever thought or knew, and one night, the lion returned. When the guards entered the lion to see why it had returned, they found the paladin's corpse inside, the cause of her death being herself. Lance suddenly becomes unbelievably worried, wondering if he would one day follow in her footsteps.
The King notices lance's sudden worry, and continued. "The blue lion always chose the most compassionate to be her paladin. She never chose the best leader, or the best fighter, but she couldn't stand a paladin who worked solo, this usually resulting in the blue paladin to be the most well rounded. In its own sense that has both good and bad quirks, but you must learn that that doesn't make you any worse than your teammates, if anything that makes you more valuable." Lance takes this to heart and whenever he's not feeling 100% he'll head over to the planet to talk things out.
There's a bunch more stuff I was thinking about, like a prince or someone who works in the castle gaining a liking for lance, which is greeted mutually, creating a jealous keith. There could be partial alteans on the planet, like part mermaid, part altean, or maybe very distant strands of the species in them, since that planet did create the blue lion, and there'd probably be some of Alfor's people there back 10,000 years ago, giving coran and allura hope. I could go on and on it's just been a thing I've been thinking...
