Marv the Crocodile

Here he is, Sin City's ultimate hitman Marv, in the Sonic-verse. And his story is probably the best yet.

One day when walking down the dark alleys of Grand Metropolis, he sees Cream the Rabbit and her Chao Cheese being attacked by thugs. Marv dispatches them *brutally* and saves her.

Cream kindly thanks Marv for saving her. For the first time in Marv's life, no one has ever run away from him. He and Cream converse and walk through the park together, eating ice-cream. Afterwards, Marv escorts her back to her mother in a hotel.

The next day, Cheese desperately finds Marv while he's working, and leads him the hotel. He discovers to his horror and devastation that Cream and her mother has been murdered.

Marv, driven by his short-lived friendship to Cream, accompanied by Cheese and Chocola, decides avenge her murder, all the while staying one step ahead of the police...and Amy Rose, who believes he's the murderer.

The brute of a crocodile is willing to tear Grand Metropolis apart in avenging the little girl's death.
