The "Castela At 21" picture kinda reminded me of the most evil tree I have ever clapped eyes on:
the Honey Locust.
I had an old one in my backyard at one house, and those thorns proved capable of:
Being used as nails for carpendry and roofing
Poking holes in lawnmower tires
Poking holes in heavy duty boots
Puncturing through (ALL THE WAY THROUGH) a human foot
Instantly dulling a lawnmower blade
Fish spear
Impaling a dove mid-flight on a windy day (doves are kinda stupid, it flew too close)
They were also called or imbued with a substance with a pH other than 7 - meaning they not only hurt you by poking holes in your weak, inferior meatbag body, but also by giving you (very slight) chemical burns at the sight of the puncture.
Said substance was also an effective anticoagulant and/or blood thinner at the site, which dramatically slowed the healing process.
I named it the demon tree. I helped cut it down, and I kept a particularly large bundle of those thorns as a trophy. Another name was the Lacerating Locust, distant cousin of the Whomping Willow.
