All true, and I agree that Doom’s beam is the strongest projectile assist for her.
But, what is X-23’s assist paradigm? What are the things that X-23 needs from assists to make her get the most out of her natural tools?
She’s in the average position of needing three things (As that is the number of things most people in the cast need from assists) from her assists: Cover/Projectile, Relaunch, and Height Coverage (which I’ve already said). Can she get by without these things? Yeah, there are many online that run her at anchor and work it, so that is an obvious. But she is at her strongest when she has those three things at her back.
This is an idea that has been ingrained into the game since Marvel 2, and has become a little less important in Marvel 3, but still plays it’s part. That is pretty much the reason every character has a Team Building thread.
Now, to get back to the point, I posted on the last page a list of assists that allow X-23 to relaunch non-specifically. She also works with any real projectile assist, though there are some standouts. As for height coverage, there are a ton that help her in this regard. The trick in choosing your two assists, if you want to have your major team focus on X-23, is to find in those lists names that overlap.
Captain America’s Shield Slash, Nova’s Centurion Rush, Phoenix’s TK Trap, Rocket Racoon’s Log Trap, Shuma Gorath’s Mystic Ray and Mystic Stare, and Vergil’s Rapid Slash assists are the ones that overlap in both the Relaunch and Cover/Projectile category, specifically Cover. If you want an assist that is both Cover and Projectile (to keep your assist safer, and with X-23’s low life that’s a pretty good idea) you are looking at Cap, Racoon, and Shuma.
Shuma Gorath’s Mystic Ray, Strider’s Vajra, Rocket Racoon’s Log Trap, Dormammu’s Purification, Zero’s Ryuenjin, Dante’s Jam Session, Deadpool’s Trigger Happy, Dr. Doom’s Hidden Missiles, Trish’s Trick “Hopscotch”, Storm’s Double Typhoon, Phoenix’s TK Trap, and Taskmaster’s Aim Master (Vertical Shot) are the assists that overlap in Height Coverage and Cover/Projectile for X-23.
Putting these lists together, Shuma and Racoon are the all around best people to have with X-23’s assist paradigm, as they each have an assist that takes care of all three problems in it. It’s in the other areas that they fall apart, specifically Vitality balance, moveset viability, DHC’s, etc. There’s also Nova, which is a very fine choice, but his issue is that his assist is all about the ground bounce, so hard to use as both Cover and Relaunch.
So that is why I say, overall, Cap is X-23’s strongest assist partner because, well, he actually fits.
EDIT: Before anyone thinks I’m trying to White Knight the Cap/Laura team, I’m not. I actually don’t particularly like Cap as a character (but then I don’t really like Doom either) as he feels kinda clunky. I use Cap because it’s just a balance of Pros and Cons, and those Pros and Cons heavily point towards Cap. It’s just utilitarianism.
