How (reformed) Elena would fit on Team Ben
A continuation of this post and a in depth analysis on Nanochips and the powers they grant.
Now I know you might ba asking yourself "Who?" and that's fair considering she only appeared 3 times in canon with the 4th being a cameo in
What being the Hive Queen means
First a link to the species and what the decoy hive queen can do.
Nanochips (also known as Microchips) are living alien objects used in Ben 10: Alien Swarm by the hive. The Nanochips are tiny, mechanical in
The Decoy Queen was the main villain in the live action movie Ben 10: Alien Swarm. The Decoy Queen is very minuscule, but is still larger th
Becoming fused with the hive not only grants you a hyper adaptable von numan hivemind that's at least planetary in range, but said chips can also make damn near any tech and mimic damn near anything you want. Oh, also you're immortal unless someone destroys every single Nanochip and the fact they can become smaller than neurons makes that basically impossible. The downside of course is that you no longer have any inhibitions.*
In fact said hyper adaptability means Elena will quickly be able to stack immunities/become highly resistant to most things (it only took like 3 hits of raw Mana blasts for the chips to lol Gwen's attack in Alien Swarm after all). Once she gets a handle on her self control she can basically control the environment (since she's made buildings come to life) and swarm her foes with not only chips but clones of people and copies of Kevin's decked out car. Which is another thing she'd be able to solve, even if his car does get destroyed she'd easily be able to fix it good as new.
She'd also be the only one that'd be able to keep up with and overcome Ben's all nighters since I doubt she needs to sleep (or breath/eat/drink) now considering her body is just a Nanochip construct. Speaking of which being such she by all rights should be immune to basically any physical attack since she has basically an unlimited supply of chips.
To elaborate on what I mean by a Gwen/Cooper combo, she'd easily be able to use her chips to form shields and moveable platforms if she doesn't just outfit everyone with wearable forcefields like the one she used to contain the chips. As for Cooper she can use her chips to make any tech she wants to on the fly (and which ability should by all rights be able to basically mimic Gwen's spells since it's WoG that Magic and Tech are just diffrent ways to manipulate reality and are capable of the same stuff**). In Omniverse she'd fully take on the Gwen role (while keeping her ruthlessness/manipulation and quasi Kevin traits if the need ever arises) of the team since there's no way she's also leaving.
* This pretty unquestionably makes her powerset in the top 3 most bs in the setting considering everything it allows you to do and overcome. The other 2 of course being Anodites/Celestialsapiens and is one of the many reasons it annoys me they wasted such an interesting character and powerset.
** That is if she doesn't learn Magic herself since even if each chip has a miniscule amount of Mana inside she has basically an unlimited supply of them and thus more than enough Mana to use Magic with. She would obviously have to learn how to manipulate Mana first but she basically has an unlimited supply of time to learn new things considering she shouldn't have to sleep and she's basically immortal.
Her role in the future
I fully expect her to have mastered the Hive by the time Ben is known as the Hero of Heroes and has used them to not only make Omnitrix City (Ben 10K's home and city of operation) but has basically monopolized architecture/construction universe wide after making smart construction tech that mimics her chips and are self repairing/adapting to whatever is damaging it. So there's no need for rebuilding after super fights or constructing buildings in mind for earthquakes etc. That and she's gone gung ho on that whole solving half the problems of the human race thing but expanding it to all species so everyone's standard of living is really high.
She'd probably also have a moniker by that point but I'm blanking on what it could be. Maybe Queen of Technology?
