As teased at the end of Episode 120 as Paparoni covers the ring in purple light, a giant enemy is coming to threaten Universe 7 and it's going to take the remaining six fighters of the universe to take it down...including Freeza.
The preview for Episode 121, titled "All Out War!! The Ultimate Quadruple Merge vs. Universe 7's Full-Scale Attack!," preview showed Aniraza easily batting away Universe 7 as they all gathered to fight in order to combat its massive size. Android 17, 18, Gohan, and Goku, are predictably fighting the mammoth as it threatens to break down the ring.
But as they struggle, you hear Goku shout for help from Freeza and Vegeta. The preview then depicts Vegeta and Freeza also lending their strength to the fight. Freeza even launches a Death Beam toward Aniraza, but Aniraza easily counters it with a ki blast of its own.
Freeza joining the fight is probably the most surprising for fans given his nonchalant nature in the Tournament, and unwillingness to really get his hand dirty before then. His involvement also disputes a major fan theory, which posited that Aniraza's name and final look seemed to indicate Freeza would be a part of this final fusion from Universe 3.
Aniraza's final form, a towering being that somehow looked organic in comparison to Universe 3's machine warriors, looked similar to Freeza. Twitter user Terez27 even broke down Aniraza's name in Japanese and made the theory seem more feasible:
"If you shorten Bollareta to his catchphrase "Bolla" (the only thing he ever says), and then take the last syllable of each character's name: ア = パンテア (Panchia) ニ = パパロニ (Paparoni) ラ = ボラ (Bora/Bolla) = ボラレータ (Borareta) ザ = フリーザ (Furīza) アニラザ = Aniraza."
But even if Aniraza is wholly a Universe 3 fusion without Freeza's involvement, it is still going to be a big enough, and powerful enough, threat to unite even the most stubborn warrior of Universe 7 against it.
