Champions Unite begins with five trainers who are invited to a remote island to participate in a series of battles that will determine a cash winner! Though things take an unexpected twist as an evil threat lurks around the island, threatening our protagonists. Andrew, a cheerful guy who has a dark past that threatens to catch up with him. Harry, a determined battler who has misfortune written in his blood. Chloe, a guilt-ridden girl who unlocks the door to her twisted history. Daisy, a loving woman who wears a mask in order to protect her true interests. James, an affectionate man who realises that his life is shrouded in secrecy. Each trainer will be challenged in various ways, forcing them to come clean with their true intentions to why they accepted the Champions Unite Challenge.
