Etna is a powerful Demon Lord from Disgaea and her abilities did improve quite a lot between the first two games. She was still humiliated by Laharl though and I’d make the case that Milim is even more powerful. A single punch is able to cause a massive crater and she can take down Kaiju with a blast. Etna is completely out of her league here. Etna is good at making cunning plans and using her abilities well, but she is just out of her league here. At the end of the day a well crafted plan can’t make up for superior stats after an extent. Milim wins.
