Introduces electric eel electrocyte cells into modified muscle tissue in the forearms and hands, creating a biological capacitor that can discharge up to 400 volts in a brief, directed pulse through skin contact. The organ charges passively from metabolic processes and requires approximately 15 minutes between full discharges. Partial discharges are possible — a warning shock of 50 volts or a sustained low-voltage current for powering small electronics. Crucible Genomics' premium installation includes forearm electrocyte arrays large enough for ranged discharge across a 2–3 centimeter air gap. The user's own nervous system is insulated through modified myelin sheaths. The modification is visibly identifiable — forearms are slightly thicker than normal, and the skin over the electrocyte arrays has a faintly ridged texture. During charging, some users report a crackling sensation.
