Yen Sid
Yen Sid is a Common Evolve Medal in Kingdom Hearts Unchained χ / Union χ.
Two Yen Sid Medals are needed to evolve a 4★ Medal to 5★, in addition to two 4★ Flora, Fauna, or Merryweather Medals, depending on the attribute of the Medal.
Players can obtain Yen Sid Medals by completing the 4★ Evolve Medals quest in the 4★-5★ Evolve Medals series of Special Quests on Fridays in the Japanese version or Saturdays and Sundays in the English version.
Yen Sid Medals can also be obtained by beating Guard Armor or Guard Armor Ω Raid Bosses. Finally, they can sometimes be obtained from Great Pretenders in Quest 174 or Quest 206 (two potential Great Pretenders), and rarely from Pretenders in Quest 270.
