[Nasis]

in Scenario1-3 Chimera ant win the war, their king didn't die ,Humanity is all death, Chimera ant consume whole planet made Earth become their perfect home

after many year of peace(?) under their king's rule ,Zerg invade this planet


in All Scenario Chimera ant have some queen for reproduce their force If they can manage to feed zerg to their queen they can create zerg/Chimera ant Hybrid, in same way and Zerg can collect Chimera ant Biomass to modify themselves

Scenario1 Zerg come with only 1 leviathan load with 1million zerg

Scenario2 Zerg invade in same level of Kerrigan invade Korhal in end of HotS but without Kerrigan and zerg's commander

Scenario3 same as 2 but kerrigan lead the swarm herself with all her most trust commander(Abathur,Zagara,Stucov,Dehaka)

Scenario4 Chimera ant somehow made peace with human after Hunter's plan to kill the king fail(and king survive), most of powerful hunter is still alive,They join force again zerg's alien invasio

4.1 same as Scenario1

4.2 same as Scenario2

4.3 same as Scenario3
