To put it simply, Pink is the epitome of the totally burned-out rocker.
Scarred by the loss of the father he never got a chance to know during World War 2, and resentful of his over-protective mother, Pink started constructing a mental wall from an early age, intending to shut out the outside world and never feel emotion again. This wall was reinforced by brutal teachers and the unfaithfulness of his wife, who left him when his construction of the wall rendered him incapable of having feelings for her.
Though he built a successful career as a rock musician, Pink's utter inability to take responsibility for his actions and his total commitment to shutting himself away from the world nearly destroyed him. After a drug-induced hallucination, where he saw himself as everything he detested, his eyes were finally opened, and he destroyed the wall that he had worked so hard to build.
Nowadays, learning to re-connect with the world, he feels compelled to share his story with anyone who'll listen, in the hopes that they won't make the same mistakes he did.
Pink can now be seen wandering around in fursuit form, thanks to Fursuiting, photos by DaIrishGoat. This version of Pink is very much the "Post-Wall Pink", after years of extensive therapy and medication.
