Fire Streak is an unicorn male who lives in Ponyville. Alongside his peers, a Purple mare firefighter and a Gray stallion firefighter, he helped clear out the Ponyville retirement home during the mysterious fires. He delivered the bad news that the elders couldn't sleep in the home for awhile while also beginning a proper investigation on why the fires started. During the investigation, he was confronted by teh well-meaning Cutie Mar Crusaders who wanted to help, but he warned them not to go in the doors he locked up, as it could be dangerous. Sometime later, he helped Mayor Mare with boarding up dangerous rooms. When the crusaders had a breakthrough, they burst into the retirement house, spooking him but when he realized they found out what really happened, he praised them but also warned them not to do such dangerous things again.
Fire Streak was kind and hardworking, but sometimes let the stress of his job get to him. Although he didn't want the Crusaders risking their lives for the investigation, h was grateful for their help and showed a warmer side to them when they succeeded.
