I might have made Z Broly too strong and need help to kill him
So im making an what if eveeything was canon fanfic and at the moment im at Buu saga, and the rules that everyrhing that exists in official material is on the table as long as it all started the same way it did on the classic anime. Goku and Vegeta are fighting Janemba and Buu, who too much people and overloaded the spirit cleansing machine, making the whole Fusion Reborn deal happen. Broly earlier in that saga went super saiyan 2 and survived a joined attack from super saiyan 3 Goku plus all the other super saiyans that exist in early Buu saga, but was weakened enough to be killed by Cell at space. When the villains escaped, Turles made an artificial moon to turn into a great ape, and as Broly had a tail on early concepts i gave him one and he turned into a golden (green) great ape, but out of control bcause its too early for super saiyan 4. Cell would be the only one who isnt avaible to fight him at the moment bsides the people at hell, Gohan has his ultimate form, Piccolo might have power unleashed and Goten and Trunks cant fuse yet. What would be a good way to take him out using something that exists in any official way and could exist in that point of the timeline?
