In greek mythology Achilles was a trojan warrior that was practically invulnerable for his heel, he died because of a small wound on his heel. Achilles father tried to make him immortal at birth by dipping him into the river of Styx when he was a child, however he was left vulnerable at the place where his father held him, the heel.

He was a greek :|

shit sorry, meant to say greek hero of trojan war

it's fine :D I'm just really into greek mythology.

A greek (Or roman, i forget) Depicts a giant by the name of achilles, who's weakspot was his heel. The joke is that he wont HEEL. Y'know, Like, achilles heel. /weird explanations

I don't think he was a giant. He was immortal because his mother dipped him in the river styx, but she had to hold onto his heels, so those were the only parts of him that weren't invincible.
