Well GrandPiece for me Issei could reach his Dragon Giant Form during or after the tournament, maybe with the dragon form and the help of Vali and the Longinus possesor he could destroys 666, Balberith and Verrine if they turn goods should be give their help for destroys Trihexa. About the power of Issei and Vali they 2 after this tournament should be above all gods, and guys like Sairog, Dulio, Cao Cao ecc when reach the full power of their Longinus should have power enough for kill gods.
