Basic question!

Collector would likely choose some sort of turtle

(I have one irl)

He currently has one that's 15 feet tall named Herman

(That's the name of the one I have irl)

Earth likes anything cute and cuddly

So likely a cat or something, probably not a dog since they're pretty rowdy

Data would want a pet but not get one because she has a very specific issue

Everything she touches gets electrocuted. She's been trying to fix the problem for a while

But currently she'd probably choose something resistant to electricity if she doesn't figure out how not to electrocute things

What about uhhhh a sea creatures that is electric proof

Maybe

knifeboi would have a harpy eagle (sharpest claws of any animal) or peregrine falcon (fastest animal on earth)

Larry IS a pet

A crow or a raven

I would say an octopus but then i realize that 401's an octopus as well
she did have a takoyaki as a friend-companion/lowkey pet so ig???

My oc has a Cybernetic Rottweiler puppy named as any of these: Personal Companion, PC, or Sara. My OC has also made about 1000+ versions of PC but they are all males, while Sara is the only Female... My OC was lucky enough to make Sara a Female...

Ooooh Nice!
Anything special about Sara and the PCs?

Sara keeps all the logs and data files in order, helps jack in combat, serious situations, etc... The other PCs all have their own thing to do... They all are code named like Stormtroopers... Like a Construction Personal Companion Generation 1 type Bravo Sector 17 is named CPC-1B17... Sara's code is just "PC"... Now, there is also a MALE version of Sara called Shaemus... His Code is PC2... He is the exact version of Sara, but a guy. Plus since he's a bit newer (by 3 years) he has more modern tools, mechanics, gimmicks, etc. Plus both of them can pretty much connect to anyone with a PC-DCC or a Personal Companion Digital Conscience Connector. This allows the Owner of a PC to be able to talk via thoughts instead of words... Though, you will need a PSOCC Device or a Personal Sight Oculus Computer Chip Device. This is an implant in your eye to see what your PC sees and what they are trying to project... It will have the same data files and access as your PC, but the PC has more access and maneuverability for it... Jesus christ that's a mouthful...

That's a lot to read, but i understand all of that.
And that's kinda complex to be honest

I know... I overthink, overspeak, and over-explain things...
