Helium
The Noble Gases are what the Halogens and other elements strive to be. Because each element has a full octet (with the exception of Helium with 2 in his outer shell), more often than they are pretty stable and respected amongst the periodic table. Each have similar yet unique monotomic abilities to manipulate substances and use that power to fight with the Halogens. Because their atomic mass increases throughout the group, their personalities become bigger as well, but are all still relatively stable. Their oxidation number of 0 makes them untouchable as they tend to keep to themselves.
Noble Gases
Helium was born with the ability to manipulate air (an airbender). He is known throughout the universe and on earth for his multiple abilities. He can be an airhead sometimes but is known for keeping things cool within the group. He aids in welding the weapons, armory, and breathing tanks of the other Noble Gases.
Neon, being a seemingly intense chracter is actually not toxic. He gets pumped with an electrifying vibe and emitts a orange color in lightings and signs when in vacuum tubes. Because he has no true cheical compounds, he sticks out as the lone wolf of the group, but still aids in fighting the Halogens.
Neon
Argon just like Helium is an airbender and aids him in welding gear and glass. She is the better bender as her ability to displace other gaseous elements such as oxygen is much better than Helium.
Argon
Krypton
Krypton also has the ability to manipulate lightning. She researched developed a glove that works much like a short range laser, zapping her opponent on contact. The prettiest of the group, aside from fighting against the Halogens, works in studio photography.
Xenon
Radon
Radon is an earth and sand bender. She has a rough personality and does not really spend much time with the others because of the threat her presence. The vibes and radiation that she emitts causes cancer and damages DNA. She only appears when the other gases absolutely need her.
Xenon, being the first in the group to be synthesized into a compound, gets along well with everyone. He has the ability to bend lighting and is often used in lightbulbs, headlights, and display panels.
