Trivia / Marvel Mash-Up

• Acting for Two: Several voice actors play multiple roles, which inevitably results in two characters who share screentime sharing voice actors.
• Adored by the Network: In the early days of Marvel Universe, Disney XD usually aired two episodes of Marvel Mash-Up each week, and only one each of the other interstitials. They and Marvel have also uploaded more of these videos online than they have the other interstitials.
• Casting Gag: Not clear if it happened intentionally, but Iceman shares a voice actor with the Ice King from Adventure Time.
• Cross-Dressing Voice: The countless female characters voiced by neither Tara Strong nor Grey Delisle.
• Exiled from Continuity: HERBIE acknowledges the absence of Johnny Storm from the Fantastic Four cartoon parody, but refuses to give the viewers an explanation.
• Fake Nationality: Wolverine's voice actor has a fake Australian accent, to parallel the fact his 1980s VA had a fake Australian accent.
• Role Reprise:
  • The Fantastic Four ones saw Grey DeLisle reprise her role from the bonus levels of the ti-in game for Fantastic Four (2005) as Susan Storm.
  • This is not the first time that Travis Willingham voiced the Hulk.
