The caped cartoon crimefighter---a kind of Superman with a tail---won the hearts of millions with the cry, `Here I come to save the day,' later immortalized by Andy Kaufman on `Saturday Night Live.' The mouse was featured in an Oscar-nominated cartoon and the series `The New Adventures of Mighty Mouse and Heckle and Jeckle' and `Mighty Mouse: The New Adventures,' from `Fritz the Cat' director Ralph Bakshi.
