Lily gains strength from positive emotions around her, such as happiness, peacefulness or hope. The strength she can gain is comparable to enhanced strength. Lily can only gain strength from the emotions of others around her, not from her own. However, it is unknown if Lily can consciously suppress this ability and prevent herself from becoming stronger. The ability shows some similarity to her father's ability to empathically absorb the abilities of others, as both abilities show an empathic aspect.
