Well, Indra's Lore (for the Time of the Chunin Exams at least) is really interesting and exciting in my Eyes.
A short Recap:
Indra and his Friend Shigure passed the Written Exam, but the third Member Silverfang didn't. At the same Time Saku passed but his Team didn't, so the Hokage asked if we want to build a new Team to make up for the Lack of Teams for the Forest of Death. They agreed and joined together. People got upset about it, but that didn't stop the Shinobis from entering the Forest of Death and doing their Best, which resulted in them being the First Team to get 2 Scrolls. In the Preliminaries Indras Motivation got Hurt, because of the Constant Hate from all the Genins that didn't make it into the Exams and accused him of cheating, but his Team backed him up. In the Preliminaries Indra fought his Friend Satsurie and Won, even tho it looked bad for him. He reached the Finals, the Arena was Full and People were excited for the Fights and drowned the Hate of the failed Genins with Cheers. The three Finalists went into a Free for All, which resulted in Broken Insides Win and granting him a Place as a Chunin. The next Fight was Indra against Saku, and after a long and entertaining Fight, Indra won and achieved the Rank of a Chunin.
Maybe this isn't exactly what you looked for, but I tried my best.
For Backstorys, I made a post in the Forums, maybe Indra will share his one there if you want to read more.
