Mr Mxypztik,the mischievous fifth dimensional imp returns to the DC universe and takes over Earth after defeating the Justice League.After numerous experiments, Bruce Wayne finally invents a gun to send Mxy back to the fifth dimension and seal it.But while chasing the mischievous imp,the Justice League end up in the Marvel universe,where they confront the Avenges.The Avengers mistake the imp as their ally, the Impossible Man(Mr Mxyzptik's doppelgänger)and try to protect him from The Justice League.Thus begins a battle that will decide the fate of two worlds. Note:I completely own this plot and Dr Strange's 'time portal' and 'Bolts of seven suns' powers' idea.But all the characters are owned by Marvel and DC companies.

Can time travel be really possible......
