As many have probably seen, Star and Stripe (Ch114) has been officially released in All's Justice this morning (or will be tonight depending on your region). With this, the likelihood of her being next season just shot up quite a bit, since she likely was being held off until she released there first (imo anyways). 

Anyways, now that we have her moveset, we might be able to get an idea for her character and skills. in AJ she has a self buff move, a projectile reflection, and two summon attacks. 

So far self buff abilities have been either Gammas or SpAs, so we could see her get one of those. from the sound of it, Strike Dabi without the life drain is the closest we have currently, just without the defense aspect. 

Compress has a projectile reflection, so it'll be interesting to see if they reuse that sort of ability for her. Mirio also sort of has one with his counter, though that's for all attacks, not just projectiles.

Her ground fist summon could easily be an ability, possibly even her Alpha. I could see it working sort of like Support Overhaul's Gamma, but with less damage/no stun. 

Finally her air avatar. I think this would definitely be the Special Action. based on what we know, it's a meter-based special with a long cooldown. I could totally see you activating this to super enhance your abilities for a short time before it goes on a long cooldown.

They could end up deviating entirely from this kit, it's anyone's guess, but I felt like it could help us get an idea of what to expect. Based on all this, she's definitely sounding sort of like a Tech to me. A self buff that you have to manage with your other skills since you can only have two active at once seems very techy, since we know she can't be an Assault AOE merchant thanks to Tokoyami. 

That's my thoughts anyways
