Alpha Sentai Al-ranger

In a society divided into alphas, betas, and omegas, three boys witness their hometown, Omega Forest, attacked by alphas while playing in the mountains. After surviving the assault, their lives change irrevocably. Two decades later, Homura, Satsuki, and Minato seek vengeance against alphas for the omegas who perished in the attack. Calling themselves Dark Omega, they use pheromones as part of their campaign of retaliation. Their efforts face opposition as the Alpha Rangers emerge to counter their actions.
