It doesn't show in the manwha but it was revealed in the novel that shark dude has abnormally high leveled stats when he was still low levelled. MC said his race is a special case and will become powerful when the level is maxxed out.
It's also said that their stats relates to their irl self as well, the dude was pretty much an all star athlete, one of those famous athletes, he might as well be a celebrity.
I don't think MC is strong enough to fight and the blue skin guy doesn't seem to have fight ability either..so why they go alone without a fighter to enemy's empire? that so dumb..this is not in modern era where talking / discusion can solve the problem (〜￣△￣)〜
