Those sprites were no aliens. They were humans. UFOs kidnapped the humans, and you had to save them.

It's Defender, not Defenders. There is only one, and that's you. You defend the whole earth with your spaceship from those alien bastards.
There is only one hero in early games. One against them all. To keep it fair, the hero has multiple lifes.

That's not your job. The UFOs do this themselves. You only have to shoot them down. All of them.

But if you really want to, you could store an attachment pointer to your UFO sprites. If a human is nearby, you set the pointer to the human sprite.
When you move the UFO, and it's attachment pointer is not zero, you place the human sprite at some constant offset as well.

It's surely not the hardest part of remaking Defender.
