Ultimos after eating chocolate

Ultimos' weakness is chocolate. It turns his skin into a brownish gray color, makes him cold, shiver and collapse, and becomes skinnier when eaten. Synaptak identified that a specific chemical, referred to as "Sucrotaxonite", in chocolate is poisonous to Ultimos and his species.
