Superhero for a world falling apart

The world is falling apart. The last country standing is the small islands of the Maldives. They have unlimited resources but very limited time before zombies infect the islands and destroy the world's last human beings. they have only days to choose the most fit man and turn him in to a superhero. The man they eventually find is not very big, has dark hair, blue eyes, and has a short height of 5'8". He is very strong for his height, and also very quick on his feet. To make him a superhero, the people come up with an extremely nutritional and oxygenated blood that helps him recharge his body faster than any other human. He can now take in a lot of damage to his body without any serious damage done. Now he just needs a flying suit and some powerful weapons to be able to take the zombies off the face of the earth. Some know him as Charlie Rogers, but most know him as Zombie-slayer.
