Dr. Hans Jermann is a traveling German doctor who operates from a village.
TycerX(Minecraft Wars), MylesC (Minecraft Wars), Magmamale go to Dr Hans along with Carlos. After meeting the good doctor, the trio leave Carlos, along with Hans, to help fetch some medical herbs. Upon returning to his tent, they discovered a secret tunnel beneath a cabinet. The trio found a nether portal and, after going through the portal, Ghasts threw fireballs at them and damaged a strange railway. Tycer went first where, after dodging fire and lava, he came to a large nether fortress.
Dr. Jermann is loosely based off The Medic from Team Fortress 2. "Jermann" may also be a reference to Mann Co., the fictional company that employs The Medic.
