Tanjerin states that he walked from the Eastern Lands to Bugaria to train abroad for an unknown purpose, and he is apparently oblivious to most forms of danger. He's very prideful and thinks of himself as a "champion of the people" despite Bugarians seeing him as only strange, cute, and unintelligent. He is very competitive and boastful, as he would be willing to fight Team Snakemouth for treating him like a child and he claims to be among the strongest bugs, if not the strongest. He loves his girlfriend Cerise, a fellow Fruity Bug that may be referred to as a "Cherry Bug" for her resemblance to a red cherry and cherry blossoms. Cerise has given Tanjerin the nickname "Tanjy".
