WangXia participated in the battle against the Japanese army outside Japan and annihilated Japanese ships with tactical nukes so he had a decent idea of his own strength. In contrast to Heng and ChengXiao, his power was meant for group battles. Demon Energy wasn’t effective on its own as bombs materialized by Demon Energy had limited destructiveness, unlike plasma bombs and tactical nukes which could have a coverage of thousands of meters. His power came from manipulating high-tech bombs using Demon Energy, powerful but considered a sci-fi attack. As a result, anyone in team China wearing the Dragonshard Necklace could easily take him down after they defended the first wave of attack from WangXia. His attacks were large AOEs but impotent on single target focused fights.
