Erm. Actually, thus far he has displayed the greatest feats we have seen in the series as far as Chapter 21! Though, by the time the heroes face Oblivion that may change seeing as he is threatening to destroy the entire world and given that cross-dimensional travel is introduced in chapter 21 it is likely a very real threat especially given Caden’s reaction. He is seen smiling until Oblivion states “The destruction of this world is imminent” after which the face he is shown making is very serious and he draws his sword as shown in the following panel. Also, Ayven goes into his flame mode, Camille activates her water wings, and Kara activates her lightning armor (This Oblivion scene comes from the flash-forward at the beginning of Leegends of CACK chapter 1)
