Umyalelo wokugqibela uqala xa i-nanotechnology ye-Desty Nova ivusa u-Alita kwisixeko esidadayo saseTiphares. Iimfihlo ezimnyama zedolophu zityhilwe ngokumasikizi, kodwa kubonakala ngathi yinxalenye encinci yehlabathi enzima. Ukuya emajukujukwini kunye neenkampani ezindala nezintsha ukuze ufunde okungakumbi malunga nexesha lakhe elidlulileyo kunye ngokulinganayo, ukukhangela umlingane wakhe olahlekileyo uLou Collins, uAlita ubanjiwe edabini eliphakathi kwamagunya aphambili esolar-system eyayikoloni. Endleleni, wenza umanyano kunye neeAlita Replicas ezintathu esele ziqale ukuzikholelwa, i-superhacker engathandekiyo, kunye noNova ngokwakhe xa engena kwiZenith yeZinto zeMidlalo (i-ZOTT), ukhuphiswano lomlo olwenziwa rhoqo kwiminyaka eli-10. Ukubandakanya indlela uMhlaba ovele ngayo kwimpembelelo yasebusika eyatshabalalise uninzi loluntu kubude bebali, imbali engakumbi malunga nokuseta kweDabi Angel Alita engakhange ibhengezwe kumtya wokuqala ibonisiwe.
