The 4th born prime of Thirteen Primes, Solus Prime is the Maker. She finds joy in creation, which is why she's particularly fond of those who create. Among her friends she is much loved both for her abilities to forge nearly any device they need with The Hammer of Solus Prime and positive supportive personality. Her one flaw is her temper that quickly flares up at any sign of injustice. She created such relics like the star saber, the mass-shifter, the matrix of leadership, and many more.
