Do I have to name All 5?
That's like, impossible! :lol

I can name Sasuke, Seikai, Tsuruhime, Jiraiya, and Saizou.
That counts, right?

Honestly, I really only remembered Aurico (because Forever Red) and Delphine (because first female team leader). Cestro's name sounded familiar when I was making the list. Because we haven't gotten to the Black/Green round yet I currently have no idea what the Black Alien Ranger's name is. :p

All I got is Aurico (Which I thought was just "Auric" for about 5 years because I misheard his name in Forever Red), and Delphine.

I've already forgotten the Blue and Yellow Alien Rangers' names :lol
You could literally call any one of the remaining Alien Rangers "Cestro" and I'd believe you :p

Aurico, Cestro, Delphine, Corcus and, uh... Yellow Alien Ranger.

The name of the Yellow Alien Ranger is Tideus. Just to let you know. ;)
