Ok, so I have some lore on Minecraft creepers. I believe that Minecraft creepers are parasitic fungi, that infect pregnant pigs and force them to give birth to creepers. The baby is then born as a creeper, instead of a pig. They explode so that they can spread their spores*. Sure, you’re not a pregnant pig, but you can still walk around and spread their spores to one.
If you die from the explosion, then the creeper spores can just feed on your corpse. To help create stronger explosions, they consume gunpowder (they don’t actually need to, but it helps them to spread their spores farther). The reason why they’re afraid of cats is because cat dander (dead skin) has a chemical that can kill them (basically, they’re allergic to cats). As for charged creepers, I just think that lightning has magic powers in the world of Minecraft (I mean, pigs can turn into Zombie Pigmen, you just can’t explain that with science). I also believe that a similar species could be infecting Mooshrooms.
What do you guys think?
Edit: *Originally from Game Theory’s creeper video
My theory was somewhat based off of his, but it’s not the exact same thing. MatPat basically said (unless I missed something) that creepers were supposed to be a evolved species of peat moss, while I said that they were parasites that infected pregnant pigs. The only part that was originally from Game Theory was the “explode to spread their spores”. However, I suppose technically count as coming from another source, so I apologize for that.
