Awesome crossover

Now that is a cool idea! The Lion King meets Buzz Lightyear!

Amazing!

This one comes from the heart: Lightyear could've been an opportunity to recontextualize the different species Disney has animated as a hub of the different animal characters Disney has created over the years. A Scar defined not by jealousy of a throne but by the loyalty and brotherly love/rivalry he has for Mufasa, given the right upbringing and circumstances. And a Mufasa torn between the responsibility of the duties a Space Ranger must carry, versus the responsibility of being a parent.
"Brother... I've got an assignment, Frusdro system, they confirmed it. There's life, and SC's given the go for first contact. Planet's population has centralized to a few dots of urban supermetropolises with a plurality of controlled biomes to account for the myriad of species they host."
"Fascinating... it reminds me of Apollo Station here."
"And they've chosen the landing zone, a town called 'Zootopia'... I want to go, but..."
"...It's two weeks travel per way, correct? Say no more, little Simba will have to train with good 'ol Uncle Scar. Besides, better your face than I when it comes to first contact."
"Oh come now, brother, I may have a gentler disposition, but you convey that we can't be taken advantage of through smarts. Even to this day I wonder how the negotiations on Valdrintrarel would've gone had you not come up with a solution to their intersystem supply chain issues right there on the spot."
"It would've gone poorly, of course. The mind is a weapon or a tool to make peace depending on the will of the wielder, Mufasa. Remember that, brother, and be safe on your journey."
"Speaking of safe, you won't have Simba train on level 3 of the combat sims like you did last time, will you?"
"Starry heavens, Mufasa, of course not. He's already on level 5, hahaha."
"Scar..."
"Oh, come on, you clearly saw it coming when he snuck into the closet and tried putting one of your Eagle-1 spacesuits. In time, he shall choose his own path, and in that brilliant, beautiful mind of his is the will to walk the path his father walks."
"I'm just afraid of him getting hurt, Scar.."
"And yet, we must not live in fear. When you chose to become a father you committed to a task requiring more bravery I could ever muster: being a dad."
"Just... don't bump it up to threat level six."
"Wouldn't dream of it. I did, after all, register the first Thursday of next month's 6:00-8:00 simulator to you and him when you get back. YOU'LL be with him on level six."
"Scar, you just cannot stand by me not being on my toes, can you?"
"Not for all the kingdoms of the African continent. I love you, brother."
"I love you too."

Crossover of the century!!!
