Appearance
Red J is a towering and very powerful anthropomorphic Cat Yokai who bares a strong resemblance to Jibanyan, though the difference is that Red J's body is brimming with muscles and built more like a humanoid. Red J has a pair of long pointy ears, a long face with a small beard under the chin, thick upper cat lips and angry-looking yellow eyes. Instead of wearing a belly warmer like Jibanyan's, Red J wears a golden belt equipped with numerous amount of sticks of dynamite. He also wears a small pendant around his neck.

Personality
Red J is a very violent and vicious Yo-kai. He showed no qualms when destroying a young boy's village and caused him to become the Yo-kai Venoct. He also showed a cocky and arrogant disposition, refering to Venoct as a "child" and even after his defeat at hands of the latter, he taunted him by describing Mighty Dog and his subordination to him.

Venoct
Red J is the Yo-kai responsible for the destruction of Venoct's village and triggering his conversion into a Yo-kai. Since then, Venoct has a fueled desire for revenge, as revealed in the last chapter of his mini-series.

Mighty Dog
It is revealed thar Red J answers to the even stronger Mighty Dog. He states he himself is "nothing compared" to the dog Yo-kai.

His Subordinates
In Venoct's search for Red J, he states he has several subordinates under his command, whose descriptions matched Nathan, his family, Whisper, and a number of students ih his school. These include an anthropomorphic hound-like entity adept on using an iron flail (his description matched Nathan's father), a beautiful, violent woman with a penchant for slicing people in half (her description matched Nathan's Mother), and an strategist (who matched Whisper) and another subordinate with no special qualities (which matched Nathan). With the exception of the latter two, all of Red J's subordinates accompained him and engaged Venoct in battle.

Abilities and Powers
According to Venoct, he has the power to crush "mechanical beasts" with his punches. His prowess was shown in a flashback, as he viciously raided an destroyed Venoct's home village.He can also make alarge purple fireball form from his hand as seen in his fight with Venoct.
