How far apart are they from each other from the get go?
And are they all facing each other lined up so to say?
The Batman Fam have the experience and raw skill but the AA students have powerful abilities. Especially when combined.
They aren't fumbling fools either they have proved themselves in battle.
I'm backing the AA.
-I see Hazmat and Striker combining their powers to create devastating damage to Team 1. And any who dodge are irradiated.
-Mettle...unaffected by the onslaught just pounds in with X23 and dominates many of them.
-White Tiger has proven herself along with Finesse to be capable combatants against X23 and X23 would carve some of these guys up good.
Finesse fought TaskMaster on practically equal ground.
-Lightspeed pounds down on hurt fighters and distracts attention away from her teammates.
-And the leader Reptil simply eviscerates Batmen with his constructs as well as holding knowledge of a future version of himself.
How does T2 win this?
Let's say opposite sides of a large warehouse
Far superior teamwork, other than Reptil, X-23 and Mettle the students have human durability, and most of the team are vulnerable to knockout gas or flash bangs
Mettle is the hardest to take down in all honesty
Also imho Taskmaster fought finesse with the kidding gloves on, he was testing her
Ahhh I hate it when locale is changed but ok.
Good luck with those gas bombs and flash bangs with Hazmat and Striker combining their blasts at T2. Pushing all back at them.
I still see AA taking this with above stips. Unless you wanna give individual reasons why T2 characters take upper hand on the get go.
Heck Reptil can become a mosquito and fly into their ground then change into a teeth machine.
