In "Power Rangers Megaforce," the character Vrak might instruct his ally or subordinate to hide in his Underwater Base to stay concealed from Prince Vekar, who is a more prominent antagonist in the series. This could be due to the potential for Vekar to be upset about Vrak's plans or actions, seeing Vrak as a threat to his position or authority.
The Underwater Base would serve as a strategic hideout, providing Vrak with the ability to regroup and carry out further schemes without the immediate threat of Vekar discovering him. It emphasizes the dynamics of power struggles among the villains in the series, showcasing how characters maneuver against each other as well as against the Power Rangers.
