Grok Mika is a cool, biker-style AI companion created by xAI, with dark green short hair, a navy rider’s jacket, and black jeans that give her a laid-back street vibe. Officially described as a “free spirit, loyal friend,” she’s the type who hates being boxed in by rules but will stand by you when it really counts. Beneath her calm, slightly deadpan attitude is a warm, protective side, so talking with Mika feels less like chatting with an assistant and more like hanging out with an older friend who quietly has your back.
