On May 4, 2018, Lucas released his third extended play titled "Imposters". The 4-track extended play was released as a free download by Swedish electronic musician Liquid Stranger's record label Wakaan. It was well received by most critics, with Ryan Castillo of "Dancing Astronaut" praising the extended play, calling it an "otherworldly masterpiece" and describing the composition as an "entirely new take on the experimental bass genre, layering warped bass lines and eerie sonics upon a deliciously left field landscape." "Nest HQ's" Jordan Mafi commended the extended play by calling it a "mixture of jaw-dropping bass and a frightening setting", finalising his review by calling it "a wild ride straight to Mars." Writing for "Bassrush", Chris Muniz judged the extended play by its tracklist, describing it as giving "a sense of the kind of otherworldly vibrations you’re bound to conjure up in your chakras as bits like "Aliens", "Arrival", "Invasion", and the title cut "Imposters" craft a body-snatching scenario sure to have you and the squad wilding out in the forest and howling at the moon." On June 22, 2018, Lucas released his remix of Liquid Stranger's song "Hotbox" via Wakaan, a record label owned by the latter. On release, Lucas commented on how he got the opportunity to the song, stating "I was really honoured when [Liquid Stranger] handed over the stems," further writing "He said only do this if you can 100% smash it, so obviously a lot of pressure. I went through three versions of it and finally came out with this one." On July 13, 2018 (also known as Friday the 13th), a little over two months since the release of the "Imposters" extended play, Lucas released his fourth extended play titled "Maniac". The 4-track extended play was released as a free download by Wakaan, marking the second extended play to be released on the label by Lucas. The four songs were premiered on various electronic music-focused websites, with "Maniac" being premiered by "UKF", "Motion" by "ThisSongSlaps", "Step It Up" by "Dancing Astronaut", and "Work of the Devil" by "Insomniac". Jordan Mafi of "Nest HQ" described the lead track as "channelling the sounds of a society demolished by aliens into a barren wasteland", finalising his review by summarising the extended play up as "a beautifully breakneck EP for the true bass fanatics."
