Nobody knows how that's possible for a five year old silver Fox to have the most spectacular supernatural strength like Samson from the Bible. But who knows, perhaps God gave Jonah the strength of Samson.
Jonah did one day caught a large outcasted demonic lion with pitch black mane and an ugly grin of perversion. Jonah has enough and killed that lion once and for all with his bare paws and his trusted razor sharp claws like swords.
Jonah even lifted a giant rock weighed over 20 tons and even 400 liters of water.
