Suggested by iKnowledge Tsathoggua is a fairly huge monster with a whole lot of power but he has to hit you in order to use that power. That’s not very likely against someone like Gildarts. Gildarts is much faster than Tsathoggua and has a lot of dangerous abilities that could deal a whole lot of damage here. A few sword swings will do the job or one magic blast. Due to the speed difference Gildarts doesn’t have to rush though as he can just get the damage in and eventually take Tsathoggua out. Gildarts Clive wins.
