Invel also believes that Zeref is the only one who should rule the world and only thing to stop him would be E.N.D. (who he knows is the Emperor's brother). To ensure that Zeref accomplishes his goal, he forced Gray and Juvia to fight to the death in order to mold Gray into a warrior powerful enough to defeat the demon.
Ice Magic (氷の魔法 Kōri no Mahō): Invel is capable of employing Ice Magic at such an immense level that he's been given the epithet "Winter General". As per Invel's own words, he is a "pure" Ice Mage: one that only freezes rather than create objects. This is proven true when Invel shows the ability to freeze Gray's Ice-Make, shattering his creation with ease, as well as to use the sheer coldness of his Magic to completely freeze Natsu's Fire Dragon Slayer Magic and the Dragon Slayer himself in a matter of seconds. Invel can also create many forms of ice for offensive purposes, which are capable to have Gray (who is extremely resistant to the cold) shiver, and even nearly freeze him solid.
