the first ep tells you basicly what's going on
the upper class of peeps, jaga being the leader of sorts, leave the planet thundera because it's about to blow up, superman style, to seek out life on a new world
then they get attaced by the mutants and they crash years and year later
they don't atually tell you why lino is the same age as wilycat and wilykit when he starts the journey but grows up to a proper adult whilst in suspended animation but no one else gains any age whatso ever

the old fella, jaga, dies in the ship and provides a obi one style mentor type for liono when he finds himself in he shit

tigra is the next oldest and leader of the war council, he's probably about 50 but acts younger, think hannibal from the a team
panthro is next, and a double hard bastard, think ba from the a team
then there is chetara who's probably another one who's in the regions of her mid 30's
and then there is the twin set of kit and cat
and shnarf

it's all good and, if you are planning to be bed ridden for a week or so, then this is certainly soemthing you should waste time watching
