OK so basically the Galactals are sealed in the exact same pink crystal that GALACTA KNIGHT was sealed in 18 years ago! And also why do their face covering opening whatevers look awfully similar? The Galactal's entrance animation when you fight it is PINK goo (AKA Galacta Knight unmasked color) being sealed in the Galactal's body. Galactals came from part of the meteors' bodies HAL tried to hide this... but NOPE and also the jamba heart looks awfully like the star of darkness...
The last two explanations come from this Failboat video so I got those two from him Link in description: https://www.youtube.com/watch?v=F9-UETQsunw
