Only fair to celebrate Crisis on Infinite Earths with the 40th anniversary approaching. The massive story made many changes to the DC universe. Some were subtle, for example Green Lantern books continued on with a new status quo (and a few tweaks to Hal Jordan’s origin) but basically no dramatic changes to canon. Others were convoluted, like the various attempts to reintroduce Huntress into continuity since she could no longer be the daughter of Earth 2 Batman.
These reboots caused entire swaths of history to be changed. Invalidating some really good stories. Here are ten retcons that came about after Crisis that hurt more than they helped. This list is arranged from the ones that were almost well done and seamless to the ones…that weren’t.
