"R-Genex", short for "Real Genex" (レアル・ジェネクス, Rearu Jenekusu) in the OCG, is a sub-archetype of the "Genex" archetype, serving as support cards. Their effects are based on Special Summoning more "R-Genex" and "Genex" monsters onto the field, thus allowing any "Genex" Deck to swarm and Synchro Summon quickly. As "Genex" cards, they receive implicit support from that archetype's support cards.
