Clancy Strikes Back! is the third episode of the second season of Ben 10: Alien Universe.


Clancy returns with a vengeance, and a plan that involves picking off Ben's friends and family one at a time--starting with Grandpa Max.

Major Events

  • Clancy returns from the original series.
  • (Non-fanon) Ben scans the DNA for Bugbite.


Main Characters


  • Clancy
  • Highbreed (brief/cameo)

Aliens Used

  • Big Chill
  • Lodestar
  • Humongousaur
  • Echo Echo
  • Swampfire (non-fanon: accidental transformation, selected alien was Bugbite)


  • Ben scans Clancy as a whole, rather than just a DNA sample.


  • This is the second instance of Ben unlocking an alien, trying to transform into it, and getting the wrong alien; the first was in Ben 10: Alien Queen with Anos.
  • Clancy Strikes Back! is considered semi-fanon, in that it no longer occurred the same way. Ben did not scan Bugbite in the end of the fanon version, instead having defeated him using Swampfire.
