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, Arnold's grandmother has to face against Vlad to save the universe.
Like the other campaign interaction videos i posted, there was some weird bugs with the audio towards Vlad, Clockwork and Gertie So i had to edit the lines into the video later.
The Danny Phantom characters are now up next as Ember is up on the list.
