Gaming All-Stars

This can be considered the non-canon "Prequel" to TFR. In an universe where a mysterious event brought all the universes together for some reason in the past, this chaotic world held together as long as it could before descending into total chaos, but in it's lowest moment, three legendary heroes would emerge and bring all the greatest heroes of history to battle the great evil that was about to arise.

Gaming All-Stars 2 (Ongoing)
Some time after the events of Gaming All-Stars, our heroes are unjusted from their wrongful end and returned to the world, albeit in a sealed state, to someday be recalled if they are ever needed again.
