I don't watch either show, but I think the characters of Danny Phantom and My Dad the Rock Star follow a similar pattern:
- Danny Fenton / Willy Zilla (The protagonist)
- Tuck Foley / Quincy (Best friend)
- Sam Manson / Alyssa (Best she-friend)
- Jazz Fenton / Serenity Zilla (Older sister)
- Jack Fenton / Rock Zilla (Father)
- Maddie Fenton / Crystal Zilla (Mother)
- Dash Baxter / Buzz Sawchuck (Bully)
