Ryulon / Ryuon

A breed of Tiger whose early design gave it feather-like fur and two large backward-sweeping horns. It looked like it had a Raiden sub-type (a breed which later became known as Sleipner), but because Monster Rancher 3 does not allow combining, monsters are classified according to where they live. Ryulons live in the jungle region known as Kalaragi. Later, they received a makeover for Monster Rancher 4 and Monster Rancher Advance, which made them look more Mogi-related, with piles of chocolate-brown fur, a thick nose and a single horn. The drastic change was noted in the monster's description.

Unlike many types of Tigers, which are solitary, this type lives in large family groups, where the leader grows the extra horns as a sign of its dominance.

Etymology Edit

Ryu is a Japanese word referring to a type of schooling, particularly in the martial arts.
