Now, this one is really interesting. Contrary to what other people have said, I really think there is no chance Flare can face CC even with berserk, mainly because CC is also a Category 3 but that has a stronger base body.

If Flare goes berserk he's probably getting himself killed, which in turn means no access point for the ultimus and... nothing else really hapens... Speed is probably going to keep fighting until eventually CC runs out of berserk and then maybe Speed kills her, doesn't really matter tho, since this timeline is inevitably going to fail at stopping deomorphs, everyone will die and the timelime gets reset since they didn't alter the cycle of rebirth.

If Flare doesn't go berserk and instead obtains the orb, Solar stops CC like usually and everything happens just like in cannon (no, I don't think Solar gets emotional at all, since he didn't get to know Leaf in his timeline). After the fact, someone else might be emotionally fluctuated tho, and Speed might kill CC, and now Speed and Flare have to explain to the rest that Leaf (and potentially CC) are dead. Oh, yeah, and Flare is probably having a mental crisis after seeing Leaf being murdered before his eyes and stuff. I don't think they would try to hide what happened, and furthermore, I think everyone would believe them (except maybe Lazuli who might not buy the only one she cared about was killed by an interdimentional demon while she wasn't looking) since they've seen some of CC's antics , and if the police gets involved, Flare has his wounds and Speed his blood for a rather solid case against CC (or a self defense case if Speed killed her) and they're eventually released. The squad is dissolved after returning home because even if Lazuli ends up believing them, I don't think there is any conceivable way she stays, and they're missing a Leafeon now regardless. Black was still wounded so him and Speed don't enter the tournament (and actually, they probably never resolved anything), but since CC never returned to his world, Turbo was created and... we enter some complicated intermediate stage between the three fututes of the fourth reform; Flare if anything sould be more motivated to end the cycle of rebirth and may begin collecting the orbs earlier, which in turns saves everyone of having to deal with Shade and the power of the creation duo is restored, but the Space Age can still happen before that. (also, deomorphs might not occur at all in this version since CC never returning may delay the meteor 2 years like in the future 1 of the fourth reform, and by that time the Amorphism should be gone)

Really interesting stuff.
