Mordecai doesn't appear in person in FusionFall, but he is a code Nano along with Rigby, obtained through the code: FFCyeeaaahhh
In FusionFall Heroes, Regular Mordecai is a playable character armed with a rake, capable of clearing crowds of enemies with its long reach. He has various heroic upgrades, as appear in the Gallery, below:
- In FusionFall Heroes, Mordecai has a hero form with Valhallen's powers. This might be the same case with Grim.
- Mordecai's FusionFall Nano has a power called "Working for the Weekend." This is a reference to the Loverboy song, "Working for the Weekend," which played on episode three, "Caffeinated Concert Tickets," of Regular Show.
