  • Jack Corvus is the only fire EM Being with an added side effect to some of his abilities, which causes HP bugs to Mega Man.
  • Corvus Noise also has a unique ability. The Corvus Noise charged shot inflicts Gravity on hit (same as Paralyze effect).
  • Jack Corvus' Grave Claw attack is very similar to EraseMan.EXE's Misty Demon attack.
  • Jack Corvus' helmet is reminiscent to that of Crow Hogan from Yu-Gi-Oh! 5D's and Yu-Gi-Oh! Arc-V. Also both characters were orphans and having a black bird theme. Also his name and elemental powers refer to Jack Atlas and his signature card Red Demons Dragon/Red Demons Scarlight Dragon.
