I also love how they have different types of leaders.
Kirk is the Captain you’d love to have as a boss. He gets stuff done, but also has fun with it. He’d inspire loyalty through Charisma.
He’s the captain you want standing by your side in a bar fight.
Picard is the perfectly-distantly, dignified leader. He’s a diplomat and archaeologist who loves exploring not only space, but culture and the nature of life. His love for his crew is shown through his desire to develop them into better officers.
He was the captain who kept you from getting into a fight.
Sisko is the most militaristic of the Captains. We first meet him in a battle, and he doesn’t back down from many fights. When Picard was annoyed by Q he complained. When Sisko met Q he punched him. But Sisko was a great tactician who also had to be a diplomat in charge of a station inhabited mostly by people outside his command structure.
He was the captain who punch someone in the throat if he thought there would be a fight.
Janeway was a scientist and diplomat. She could be hard as iron, but she was absolutely devoted to her people and would do anything for them. Her loyalty would cause her to occasionally cross the line, however. More than any of the captains, she wanted to develop her crew into leaders. They had limited options for advancement, but she tried to give them all opportunities to grow. She also didn’t see any sense in playing fair if she was in the right.
She was the captain that would bring a gun to a knife fight.
