I made a baby Leo plush! He’s a lil burger shaped guy. He can stand, sit, and sploot! I’ll be releasing the pattern in my shop at a later date along with a few Leo plushies!

So, as we saw, future Leo was vaporized by a blast from a Kraang ship and died instantly.
Let's talk about that.
The good thing is that Leo didn't feel a damn thing. Not only was he not aware that the blast was coming (so there was no anticipation), but his nervous system was gone before it could send pain signals to his brain. Just based on what we've seen in the future, Leo's death was the most merciful. He basically just ceased to exist.
Now the bad part.
It takes about 2.99 gigajoules to vaporize a human body. One gigajoule is 1 billion joules.
So if we do the math, Leo got hit with 2,990,000,000 joules in a split second. 136 joules are considered lethal.
Now considering Leo wasn't 100% human, this number may be different in his case. Regardless, he was vaporized so he either got hit with 2.99 or more (already enough to completley melt 5,000 pounds of steel).
