4. That Time Robin Replaced Him
When Batman "died" in the regular DC Universe, former Robin Dick Grayson ditched his Nightwing mantle and became the new Batman. However, on parallel universe Earth-2 there exists a Robin who was never able to really grow up, as when his mentor decided to retire, he became a bizarre Robin/Batman hybrid whose costumes was a mixture of both heroes. He looked ridiculous, and if you're wondering why exactly this is an embarrassment to Batman, can you imagine how he must have felt with his enemies thinking it was him in that awful suit?
