I think everybody knew Samus's metroid fusion was going to become an issue at some point.
Remind me, where's her suit again?
She has to find the Chozo temple on this planet so she can get a new suit. Yes, there is a Chozo temple there, I think you'd be hard pressed to find a habitable planet that DOESN'T have a long forgotten chozo temple somewhere on it. I don't think Samus can kill the X without it, sure she can absorb them when they're in their blob form, but first she has to "kill" the host, and the weapons that give her the ability to do that are in the suit.
True, but Crono can always kill them for her.
WRONG! Crono CAN'T kill them because he has no magick, and his sword would be of no use on X hosts like Ridley. Basically, since Samus' ship is gone and her suit is gone they are A) screwed or B) gonna be saved by a convenient and possible poorly conceived (doubt it with Ryan though) plot device n.n
My money is on B personally :P
Crono may have lost his Magic, but he still has his sword techs. He could use those even before Spekio unlocked his Lightning spells.
Not to mention, there is still the E-poch.
I will point out that Crono's sword techs suck ass, especially in boss fights beyond the Spekkio encounter. As for the Epoch, it can't go into space yet and Lucca doesn't know Samus and Crono are in orbit. Though who knows, Nack might save them for some reason :P Anyway, against a Ridley X Crono is royally screwed by himself without his magic, it'd be like the time Crono took on Lavos alone, he got fried.
Crono has some pretty nifty Dual Techs, if he can find someone to pair up with. Frog was the best pre-magic partner for him, though, and I somehow doubt he'll be in this comic...
