Nickelodeon All Star Brawl 2's Story Campaign has original writing for it's characters so it means these characters get original dialogue and even some interactions towards the NPC's and bosses.
In this video, the new generation of Avatar has to save the universe.
Like the other campaign interaction videos i posted, there was some weird bugs with the audio towards Vlad, Clockwork and Korra. So i had to edit the lines into the video later.
Still going with the Avatar theme going as the last airbender himself, Aang is up next.
