Luna in her cool new streamlined cheetah form immediately ran out out of the Unforeseen Simulation Joint at an unprecedented speed and as she ran down the road as fast as she could towards UA high school something was happening back in the building that would cause any horror writer to give the villains a standing ovation, the students were separated!
Inside the Unforeseen Simulation Joint 'mister foggy portal man' seeing the students grouped together decided to separate them so it would be easier to kill them, so that they could lure out All Might. To do this he uses his quirk, that seems to be a kind of warp quirk, to spread a fog around the students position which would cause them to warp, some were lucky as they realised and had ways to avoid it, others realised but couldn't do anything and the rest were stupid and didn't really understand what was happening.
The only person that wasn't warped to somewhere else was Aizawa who was currently in the plaza fighting hordes of villains one after the other using his fighting expertise and powerful quirk called Erasure that allowed him to, you guessed it erase, his quirk allowed him to cancel out another persons quirk powers and abilities as long as he looks at them and concentrates.
This powerful hero was currently the centre of attention for the huge group of villains and at the rate they were going, they would eventually beat him, but not yet.
Moving on to the groups that were teleported. First was the flood zone and the people that were sent here were 'vegetable boy', 'froggy' and 'smarty pants'. These students, once warped, went in to slight shock, well 'vegetable boy' did and he was about to be devoured by a villain as soon as he appeared, but unfortunately or fortunately, depending on how you look at it, 'froggy' saved him at the last second, like a proper hero, and used her frog like tongue to pull him onto a boat at the centre were she was warped to, next she uses her tongue to pick up 'smarty pants' as he was in less danger and once he was safely on the boat, they devised a plan.
The first step was for the three of them to group together, next was for 'froggy' to grab on to them and finally 'vegetable boy' flicked the water creating a water explosion sending them to outside the flood zone, thankfully it worked otherwise they would have most likely died. Unfortunately however the annoying green haired pervert had the brilliant idea to go towards Aizawa and try to help him even though he would be completely useless and probably make things worse with his dumb heroic spirit.
Whilst this was happening, in the landslide zone, 'Icey boy' and 'the invisible one' were currently standing in a frozen paradise as 'coldey-locks' had completely frozen the place without knowing that his invisible classmate was there, obviously it wouldn't be very good invisibility if anyone could see her.
Moving on to the mountain zone you could see a wonderful woman with most of her skin exposed, a girl going through her emo phase, it might be permanent though, they were both under a large insulator sheet, which was probably why Momo was so bare, and a yellow haired banana, that also had the braincell of a banana because he had just used too many volts with his lightning attack, causing him to become even more stupid than he already was, which explained the insulator sheet.
Finally in the ruins zone the 'manly man' and the 'angry dog' were running around like they owned the place as they used there place causing destruction constantly, they were not having problems even with the groups of villains they were facing.
Unfortunately not everyone was having a good time, especially in the central plaza where Aizawa could be seen having a fight with the 'handy man' who managed to touch him, which caused his quirk to activate allowing him to disintegrate the lazy teachers elbow. Fortunately Aizawa manages to get a good hit in on the emo villain, but he can't continue as a big scary black thing with red markings and an exposed brain comes out of no where and starts to mercilessly beat the poor man who by now just wants to nap.
Unfortunately however his students are not very good at hide an seek, so the 'handy man' easily spots them and decides that they will be his next target, after all Aizawa is beaten and All Might isn't here yet.
Right on queue though All might appears and saves the day. Never mind he has a long and exhausting fight with the thing known as a 'Nomo', after all It was meant to kill him, so it was quite a powerful entity. Just like that a possibly traumatic experience was coming to an end.
