So we all know that Alien Covenant is quickly approaching theaters and it lead me to looking closer into the Xenomorphs.
I had an idea for a character based around the idea of David with an Eidolon based on the iconic Xenomorph. I'm hoping to call upon the brilliant minds of the pathfinder community to help me pick the most appropriate construction for this monstrosity.
I'm not as worried about my summoner itself, unless you have a suggestion for taking extra evolution a certain number of times. The character is a half-elf with using the alternative class bonus for the extra evolution pool.
The current design I have at level 6 is what I'd call the drone:
Body: Biped
Evolutions: Claws x2, Rend (claws), Energy Attacks (acid), Ability Increase, Strength, Tail, Reach (Claws), Improved Damage (claw),
I'm looking at a lvl 20 build I'd call the Queen:
Body: Biped
Evolutions: Claws x2, Bite (and improved), Huge Size, Ability Increase Strength, Improved Damage (Bite and Claws), Reach (Claws), Rend (Claws), Tail, Sting, Energy Attacks (acid), See in Darkness, Acid Immunity
Any thoughts or suggestions? I've also considered switching to a quadruped, but it seems to deviate from the movies. But it also seems appropriate to maybe going with a pounce build.
Thanks for the help everyone!

Fair warning: Reach and Improved Damage only apply to a single attack, even if the attack type comes in pairs. Maybe put reach on the tail?
Guessing by the massive list of evolutions, this is an APG Eidolon, right? Neat. Tentacle may be a decent attack if you want to represent that tongue-thing. You can also flavor it by putting Reach on the Bite. The climb speed evolution also seems fitting.
Bonus if your Summoner has a horiffic scar on their stomach, representing the first time their Eidolon was "summoned" into the world.

Ok, I love the idea of the scar. That's awesome.
I am enjoying the benefits of an APG Eidolon, but have considered switching to the "chained" version. However, that's only a small possibility dependent on my GM.
Thank you for pointing that out about the reach feature, I didn't realize that. However the improved damage applies to an attack type, not a single attack.
"Select one natural attack form and increase the damage die type by one step."
I may switch the reach to bite. It'll emulate the bite focus from the movies.

A Serpentine base would make for a good Chestburster in the early levels. Especially if you start with a Small size Eidolon, but the low speed would hurt the larger forms.
Level 6: Drone
Biped
1- Bite
1- Bite
1- Tail
1- Tail Slap
2- Grab (Claw)
1- Climb
1- Improved Natural Armor
1- Reach (Tail Slap)
*1- Sticky
Level 20: Queen
Biped
1- Bite
1- Bite
1- Tail
1- Tail Slap
2- Grab (Claw)
1- Climb
1- Improved Natural Armor
1- Reach (Tail Slap)
3- Blindsense
10- Large (Huge)
2- Limbs (Arms)
1- Claws
1/*1- Immunity (Acid)
*2- Trample
*1- Sticky
This is for thematics and without any Extra Evolution feats and would make a pretty good Xeno Queen I think... 36 STR, +20 Nat Armor, Trample and 6 natural attacks (with 4 grab attempts) make for a good engine of destruction. Feel free to drop stuff you don't like OR take Extra Evolution to add a few more... I could definitely think of a few more I would add ;)

Don't you need to add an extra head to add an extra bite attack?
Edit: Also I love this idea and when I get to my books I'm gonna try to build one myself, great idea.
The extra Bite evolution would use 1.5 STR on damage rolls with the bite attack. If it was for an additional bite attack then, yes, you would need an extra head.

Ah, I misunderstood, that's a great way to emphasize the double mouth. Flavor wise I think I would go with sting instead of tail slap, then add tail slap when it becomes a queen sized one. I know you can use bite and gore as part of a full attack, can you use sting and tail slap the same?
This idea also led me to a few ideas. Like an all summoner party with movie monsters, probably evil campaign. Or the characters are all Summoners, and their eidolons have gone rogue and are hunting them. Or maybe just a series of villains like that. Oh, you could use the brood master to do gremlins or critters (from their respective movies), and shadow summoner for something like Freddy. One of them is a werewolf who is actually a synthesist, and they thought he was just a friendly npc.
