Chinese
In Chinese mythology, the god of war is Chiyou. Chiyou was described as cruel, greedy, and tyrannical, with 81 clans (supposedly) in his kingdom. Dragons in Chinese mythology are considered to be the most powerful and divine mythical creatures. Not only did they symbolize great power, but they were very supportive of gods and heroes. A power-mad Chiyou could easily enlist the help of the trickster Monkey King to sway some of the dragons – Dilong, the Earth Dragon; Jiaolong, Dragon of Floods and Sea; and one of the Dragon Kings. Using their power, Chiyou has been able to rule over his kingdom with an iron fist, warding off any potential invaders and rescuers with powerful floods or devastating earthquakes. The Dragon King is basically his last resort weapon, a symbol of power for the people in the kingdom who defy him and any dragon stupid enough to try and free their brethren.
Of course, the rest of the world won’t be happy with this. In the outside world, a young soldier comes across a dragon, who tells them about Chiyou’s mistreatment of their kind and imbues the human with their elemental power (each element unlocks a new melee weapon as well). Eager at the prospect of more power, the human devises a plan to free the Earth and Sea Dragons, the remaining dragons will help assault Chiyou’s fortress and end his reign of terror. It won’t be easy, but taking on the god of war rarely is, especially when he’s got a dragon under his command. But if the human does their job right, they’ll have an army of dragons to help them.
