A Tyranid hive-fleet tendril vs a planet of Xenomorphs
Assumptions:
Xenomorphs can reproduce using Tyrabid bioforms, to produce new Xenomorphs with the characteristics of the Tyranid they incubated in.
Tyranids can evolve to ensure no Xenomorphs can reproduce using them, but this takes time and the Xenomorphs also adapt their reproduction methods.
Can the Xenomorphs hold out against the Hive fleet fleet tendril for 3 months?
