This just in, the aliens Valky, Icarus and Nackle are not the ones from Ginga S. Their case is just like Alien Zetton: new aliens that voiced by past actors.
We've been mislead....
Also, the names of these aliens are below:
- Valky: Halky/ハルキ (man, sounds like Haruhi Suzumiya)
- Icarus: Icary/イカリ
- Nackle: Nackley/ナクリ
And this cute baby Samekujira is called Jolly/ジョリー
