Implementing xenomorph aliens in D&D 3.5e [closed]

Question

As we know, aliens had inherited memory as seen in this review:

Ripley's genes are all right too: 
They allow her reconstituted form to retain all her old memories, 
as if cookie dough could remember what a gingerbread man looked like.
— Roger Ebert's review of Alien Resurrection

Now if i implement aliens in my D&D 3.5e campaign setting, would an alien get all experience of ancestors when get spawned as a chestburster and grows full?

I know the only alien type that can produce another alien is a queen alien. If first queen's experince gives an extra 10-class level to her, then its offspring queens get all those experience too?.(10-class level is an extra to the natural hit-dice of queen(10d6))

Can we say that 3rd queen has 3x experience of the first queen?

Then each new queen alien will be much more unstoppable. What could i add to balance this? Starting from zero-experince and add the "waiting" experience as alien grows in natural hit-dices?

Also the drone, runner and praetorians would be stronger than before as inherited from newer queens.

Most importantly, if victim is a level-20 rogue + level-20 fighter, then would the final alien from this victim be a demi-god? (also an alien produced in tarrasque would be something epic)

Answer 1

Actually, my best luck was using Mechwarrior to translate the AvP world to an RP. But if you specifically want the sheer and absolute horror, you might want to look at the lycanthropic/racial templates (See Creating a Lycanthrope on d20 SRD). Doing this, you'll need to create a base race for the Xenomorph and then what you probably want to do is just apply a template. Using the rules for Lycanthropy means that you take the base critter that you are splicing, and take a bonus to your stats equal to the average of the same stat of the creature -10 (For example, a werewolf gets +2 Str because a wolf has a 12 Str). Since we really don't see many supernatural species or abilities in the movie series, we don't know what abilities are exactly genetic enough to pass to a half breed. That will be up to you as DM, just make sure to increase the CR/ECL to match.

Alternately, you can just create a Xenomorph template and apply it to the critter/character you just facehugged and chestbursted since that character is effectively gone anyway (although there are resurrection rules so, necromantic cult keeps a troll alive and keeps facehugging it as a plot arc?). The template could be a boost to physical stats, a penalty to Cha / Int, add Darkvision and natural attacks appropriate to size, and maybe use Shocking Burst magical weapon ability, but make it acid and deal the damage to someone that attacks it, treating slashing as a +1 multiplier to crit.
