The Metallion (メタリオン, Metarion) is a plant found in the Dark Continent. Its unknown properties caused it to be designated as the "Alchemy Plant Metallion". In the past, an expedition sent by the Kingdom of Kukanyu managed to get the plant, but went off-route on the way back. Many members contracted Zobae, and the plant died. There were only six survivors, of which one was Beyond Netero and the other a Hunter that had been infected by the disease.[1]
