Awesome art! This is so cool, I can imagine it now. The war breaks out and the fake heavenly knights corner the exhausted original heavenly knights, who are not recovered from their fight with Luka. They are surounded from all sides, but just as the enemy moves in to finish them off, the fantastic four unleash their full power. A power so huge that it causes a deafening roar and a bright light that is so bright that it can be seen from space, it's like a solar flare. But this kind of power can only be unleashed when the fantastic four combine their own full power together.
And then this epic battle theme would suit perfectly -> [link]
