If i draw a character that kind of looks like another character that already exists what will happen?

ok i want to make a cartoon when i grow up but i am a huge sonic fan and my character kind of looks like silver the hedgehog if i draw him in a cartoon what will happen. my guy looks like silver just with a jacket with a shirt and pants, biker gloves, different design boots and a little arm band on both arms to support the gloves, and he goes super fast and uses fire, and if he takes off his shirt his body is a little different but with a bathing suit. someone answer me please!
