Screechereen is based on XD001 (Shadow Lugia) from Pokémon XD: Gale of Darkness. it is also the complete opposite of Badias, which evolves with ugliness; Screechereen is evolved by love. Its Sonic Screech is based off of Hyper Beam, a move that only certain Pokemon and Tiny'Mon can use due to its destructive properties; its Sonic Screech could also be based off of Aeroblast/Shadow Blast, as it is currently the signature move of Screechereen just like Aeroblast/Shadow Blast is the signature of Lugia and XD001 (Shadow Lugia), respectively.
