The Ring Shadow is a ring-themed Shadow Monster and is the main antagonist in episode 18 of the 2014 TV series Ressha Sentai ToQger.
He was voiced by Kenta Miyake.
The Ring Shadow is armed with the Jewel Gauntlets as well as the Headache Rings, which he uses to affect people around his Henzutsū Dark Station. He has a possessive personality. The Headache Rings he creates causes unbearable headaches to the person who wears it whenever his/her name is heard, and can only be removed by Ring Shadow himself.
Zaram, who has once again been pulled into the ToQgers' fight, falls victim to this, and was freed from its effects after accepting the human name Akira Nijino from the ToQgers.
After the now 6 member ToQger team defeats him in his human size, Ring Shadow grows into a giant where his diamond-hard defenses are too much for ToQ-Oh to handle. ToQ 6gou brings out the Drill Ressha to form ToQ-Oh Drill, which is able to destroy Ring Shadow once and for all.
Ring Shadow was among the Shadow Monsters that were brought back as ghosts by Tombstone Shadow, they were weaker than when they were living and unable to grow when defeated. He was destroyed again by ToQ 4gou and ToQ 5gou's Scope Ressha-enhanced ToQ Blaster (Uchimasu) blast.
