"Alchemy Beast", known as "Alchemic Beast" (れんきんじゅう Renkinjū) in Japan, is an archetype of cards used by Amnael in the Yu-Gi-Oh! GX anime. The main strategy of this archetype is banishing your own monsters to power up your stronger monsters and relying on the direct attack ability of the weak monsters, all of which have 500 ATK.
The monsters are based on common base metals and animals used in alchemy to transmute and refine gold and the alchemic processes, based on 4 of the 7 main stages in transmutation, falling under calcination, dissolution, separation, conjunction, fermentation, distillation and coagulation. In the Japanese version, the word "of" is added before "the" in the monsters' names; for example, "Alchemy Beast - Leon the Lead" is called "Alchemic Beast - Leon of the Lead".
