Paradoxx

PARADOXX (nicknamed 'Padok' by the community) arrived in Pump It Up 2015 PRIME as that version's final boss. It was first unveiled at KPF (Korea Pump it up Festival) 2016, during the closing showcase after the speed finals; host EXC framed it as an experience piece and a taste of what the WPF might hold. The line EXC used to kick off the song became a running joke among top players, and the series later canonized it as a meme in the BGA of Nyarlathotep in Pump It Up XX. The Single chart shipped first, with the Double following in patch 1.19.0, and a Short Cut was added in XX 2.08. On English-language cabinets the song shows as 'Paradoxx' on the select screen but appears in full caps, PARADOXX, on the results screen.

Mechanically it is a remix of 1950 and Yog-Sothoth at 220 BPM, the same structures as the originals sped up 1.1x. Every difficulty opens on the calm Yog-Sothoth section, then alternates with 1950 while steadily ramping up toward the dreaded 'speed part' piano run, a textbook late-song breakdown. The S21 blends Yog-Sothoth S18/S21 and 1950 S20 arcade patterns: easy early, with fast drills and twists in the middle and a final run that decides the clear. The S23 imports softened versions of level-23 charts and is won or lost on the closing piano run. The S26, the first Single 26 ever, plays reasonably until its signature finale: a 32-beat siderun that is nearly impossible to hit clean. With PHOENIX-era difficulty inflation it is now widely regarded as an 'honorary 25.' Clearing it earns the [PRIME] SINGLE BOSS BREAKER title.

The D28 was the first level-28 chart in the entire series and, together with the S26, crowned PARADOXX as Prime's absolute final boss. It was built by EXC, who reportedly spent around nine months refining it. Before the final patch it was the only remix with locked steps: unlocking the D28 required an A rank on the S26 plus a payment of 28000 PP. Its closing stretch packs wide-movement runs, staircases, Half sections and a brutal finish, and it carries a symbolic note count, 3000 originally, trimmed to 2500 in PHOENIX. Only eleven players worldwide have ever scored the D28 break-on, beginning with FEFEMZ* in 2016. For years fans debated whether it outranked NXSB, until clearly tougher charts such as 1949, Shub Niggurath and 1948 settled the matter. Clearing it grants the THE MASTER and [PRIME] DOUBLE BOSS BREAKER titles. The Short Cut, meanwhile, debuted the series' first S24 and first D26.
