Leonhart is in exceptionally high spirits, especially after absorbing the power of two individuals. This euphoria peaks as his vampire gene undergoes another upgrade.
The highest enhancement for vampires is only up to the rank of Prince, and even this is incomplete, requiring continuous strengthening to perfect the gene. Once this level of gene enhancement is achieved, it bestows the ability to absorb others' power and genes – the true essence of vampirism. Leonhart's physical abilities are formidable, but due to Team Pacific being bred for battle, his combat experience is pitifully limited. Thus, he's had no chance to absorb the genes and powers of stronger foes, rendering his seemingly powerful trait somewhat useless. This was his primary reason for wanting to defeat Zheng.
