WI: Doctor Who/DC Crossover

[redsycorax]

In the Infinite Earth thread, the Fourth Doctor ends up shunted into Earth-One's universe. Coming across the ailing planet Krypton and confronted with the reality that million of that planet's inhabitants will die, he innocently changes that universe's history ... and saves Krypton from destruction, true to his character. But what will the consequences of this act of humanitarianism be? 

Hope dans enjoys this one!
