I think Atlas finally redeemed himself during War of the Realms. He was with Giant-man Scott Lang when he was trying to rescue Stature Casey.
Fixxer had been mostly on the side of good. During dark reign and under Lukes Tbolts team. Don't know why he switch back may be the time with Kobik messed him up.
It really is just Moonstone that hasn't changed. hope they go back to the Busiek & Nicieza days and let Karla be redeemed.
But the good thing about her being a villain, is she gets to appear more often. Well compared to the rest of the tbolts. (recently she cameo in blackcat, in strikeforce and now in ravencroft.)
