Chlorine

a.k.a.

• Cl (though not shown as such in the series, to the best of the Editor's knowledge)

Intro

Episodes

• "AB Chrysalis": Unnamed planet encountered has significant chlorine in its atmosphere, and its native people breathe it. Rash action by Alan strands him in a room full of chlorine. Maya transforms into a chlorine-breathing creature from Kreno to rescue him.
• "Beta Cloud": Maya suggests to Tony that they fill the Hydroponic Experimental Section with chlorine, and Tony lures the invader in there remotely, in what turns out to be a futile effort to kill it (the Alphans later discover it is robotic).
