(six moves?)(I'm okay with the first part but only four moves seem a bit short.)
Mystery Man: Brick Break
*Rodrick jumps up and comes down on Earnest with a karate chop-like attack*
(A bit higher. Maybe ten)(six moves?)
Rhoki: Ernest, Take the hit and use Payback!
*Ernest takes major damage, being super effective, and strikes Rodrick with double the damage*
Rhoki: Double!(A bit higher. Maybe ten)
*Rodrick doesn't take much damage due to him having a double resistance to dark,his high defense stats,larvitar's overall weakness and because he used bulk up previously*
Mystery Man: Finish this. Brick Break.
*Rodrick moves in for a swift chop to the neck*
*Rodrick stumbles a bit when he misses but finds his footing*Rhoki: Double!
*Ernest creates after images of himself and you miss*
