Back to the Future - end of Freshman Year

The story goes like this...
It's the end of the school year
They have just a few classes and finals left
Game start was a gym class where they play, instead of 'save-the-citizen'
they play bank robbers and heroes
Quick bank map, and have at each other
As luck would have it, the Desol and T-porter/street thug were both on the first 'bank-robbers' scene, So I asked them for their first actions ....
Then had Coach Boomer blowing his whistle, "OK that's round one, now you two teams switch sides ..."

I was afraid those two problem powers would be on opposite sides, but it worked out

So then, they had just two finals to prepare for
First, a paper due in history about their favorite hero from WWII.
which they could answer using any comic book hero they knew off, which the understanding that the character would be writing about some close analog from the game world
And Second, they needed to be able to study up for one question of their Mad Science Final
which was:
"name 5 of the 12 dimensions relevant to Teleportation" :-)
Naturally they can't answer it correctly, and since it's a practical final
Mr Medulla t-ports them off somewhere, saying that if they aren't back by the end of class they fail.
:-)
They land in their own city in June 1942, and end up saving the cities hero group, which had been captured by the 'Crimson Cranium." Who they find giving a maniacal speech in German
while in a hidden base under the still-under-construction, Empire City Center.
In the PC's time that auditorium is converted into a Superball stadium, because that base becomes the secret home of the Evil High School, Empire High.

The PC's rescued a bunch of heroes (interestingly enough mostly those they'd just written research papers about, hmmm?) And as they exited, one of them noticed a stock pile of TNT in a store room.

They are returned to their classroom just in time to pass the test, by Tommy Tomorrow (from Red Panda) whose t-travel gadget has 15 dials! (not just the 12 Mr Medulla expected) :-)
