Does metallo have a kryptonite power source?

Metallo is a DC Comics supervillain who appears mainly as an adversary of Superman. All versions of the character are powered by kryptonite, the radioactive mineral that weakens Superman and gives Metallo his energy. In the comics, the kryptonite is either implanted in or surrounds a partially or completely mechanical body, allowing Metallo to draw power from the mineral and maintain his robotic form. The character has been adapted into various media, including animated series where he is voiced by several actors and appearances in the live‑action television series "Supergirl." The consistent use of kryptonite across all iterations establishes it as his defining power source.
