assume how the character above you will die

well--

//there's actually a high chance of risk he could die because of it as he's friend with Erin
who sometimes takes him to her homeland to visit her family (her dad obsessed with bees)

Got stung by bees

Scared someone so bad that he got punched in the face real hard 

Probably got caught at the wrong time in a graveyard

With those scars I imagine he has a lot of enemies and got into a lot of fights, maybe Santos eventually made an enemy with the wrong person

i feel like he maybe got backstabbed by a friend (literally) 

i think he would die from an unexpected bear or moose attack

I’m thinking Felix dies in battle against a powerful witch, sacrificing himself to save his fellow pilgrims.

With the mix of DNA, maybe his body (like white bloodcells!) gets confused and attacks itself as self-defense?

There isn't a lot of information given on their profile, but I will assume Irura is a bad guy. They look spider based, so I will say their own venom is used against them in a final battle!

Probably by passing away peacefully?
