Who else here has an alter ego?

Question

Mine is called Tom, he lives in a tree

Answer 1

Mine doesn't have a name.. but when I go really manic, I become my own alter ego hanging under invisible strings like a mindless hand puppet.. constantly making stupid decisions and thinking many thoughts that the normal me would never consider .. the mind is capable of some really crazy things under the right (or wrong) circumstances.. :)
P.S. ... Tell tom I said hi :)
