Ray Palmer, "Atom", had died with the JSA on a mission, only a while
later to
be discovered he was a Durlan all this time. The "real" Ray Palmer
never
returned form halting the alien INVASION, and was suspended in a pod on
the
Dominators home planet, along with J'Onn J'Onnz, Black Canary, Hawkman,
Kilowog, and Batman for at least four years. Rescued by young Justice
he
returns with the other heroes back to Earth, trying to figure out how
to go
about recapturing all those lost years.
Powers
The Atom's Current costume, which is made of material from a white
dwarf
star, enables him to reduce his size and weight by transferring part of
his
mass to another dimension. He can reclaim mass friom that dimension in
order
to increase his size and weight or both. The atom controls the costume
mentally through an encephalotronic grid in the costume's headpiece
keyed to
his unique brainwaves. The Atom can mentally make his costume appear or
disappear by shifting most of it's atoms to or from the other
dimension.
the Atom has a mental link with the white dwarf matter to which
he's
been regularly exposed, most of whose mass is in another dimension. He
can
draw on that mass to punch with super-concussive force.
Over time he's learned to use his size to his advantage, including
the
ability to travel through the phone lines, allowing electronic move him
along, or travel through subatomic particles.
An Olympic-level gymnast and an excellent hand-to-hand combatant,
which
he's mastered at a variety of sizes and weights, he has exhibited great
adaptability to fighting at any size, even with a sword.
