I'M CRAZY FOR THIS AAAAAH
-------------------------------
Wellp, I always thought it was a bit weird about how alfor just built these five 'out of nothing'. So my kinda Headcanon is about there being more lions, but not neccesarily able to merge with voltron or anything.
I felt good with the number of 5 'Prototype'-Lions that Alfor built to study how they'd have to work. At first he used up a minimal amount in the first one, a little more in the second and then Taking equal amounts for The last three and an extreme amount left over for the voltron lions.
I thought that each of them could have been coated by a metal?
I went with Rose Gold (Most likely he thought about Allura when choosing it), Silver, Platinum, Bronze and an black-purpleish Altean Metal (Couldn't come up with a name for it)
Sadly, I need to say that in this Headcanon, two of them didn't even work propperly or develop a true concience (Which are Platinum and the Altean Metal).
These two are thought to have been destroyed with Alteas downfall...
It might sound a little ridiciulous but what do y'all think?
