The one and only, Thor's stepson.
Some say that when he's driving on an oval, Ísleifur doesn't turn left... the Earth turns right. And when he does push ups he doesn't push him self up, he pushes the earth down.
And that he was once bitten by a king cobra, and after 5 days of agonizing pain... The cobra died. All we know, is that he's called Ísleifur. He has been killed 7 times and been reborn 12 times, he has 36 kids and 69 wife's. And his nemesis i named Salmar.
