space to switch backdrops. so yeah, here's the storyline for him i guess: TSOS Blue had finally found where Bypbi was, and decided to have a friendly rap battle. Unfortunately, TSOS Blue was toxic to Bypbi because of the extratone he used, and it angered him. He then shifts into his 2nd phase, gaining a few floating shapes and some extra rings. His extratone was now higher, and TSOS Blue struggled to keep up. Still, TSOS Blue won and was toxic yet again because Bypbi didn't sing normally. That's when Bypbi had enough, and shifted into his 3rd phase. Somehow, he manages to get these weird... I don't even know what you call those. Regardless, he turns completely red, and his extratone shifts into hypertone a few times during the 3rd song. And then, Bypbi ended up getting distorted beyond recognition at the end of the song, losing control of himself as he shifted into his final phase. Despite Bypbi looking like a total abomination, TSOS Blue didn't really care much about that. TSOS Blue still won in the end, making Bypbi explode into the remaining shapes he was still composed of. Bypbi had lost.
The red and white things behind Bypbi in his third phase are actually inspired from Spectra's final form. By the way, Spectra is made by @Spectra473 I guess Bypbi's technically connected to the JSAB universe now, huh? also i spent way too much time on this-
