Alternate Universes Collide Again is a story mission in the video game, "South Park: The Fractured But Whole".
Plot details follow.
Defeat Alternate Human Kite
This time, the fight is in the backyard, and Alternate Universe Human Kite has blockaded himself behind some obstacles. Allies with charge abilities, like Captain Diabetes, are especially helpful here to get the fight done with quickly. Alternate Universe Human Kite's only offensive attack is an upgraded version of his Eye Laser beams that hits five squares in a cross shape; keep your allies spread out to reduce the damage they'll take on his turn.
Defeat the Broflovskis
Once his backup joins the fray, Alternate Universe Human Kite will run to the opposite end of the field as Mrs. Broflovski stands in front of him. In order to triumph, both of them must be defeated; the original Human Kite will join the fray after his mother takes damage, but he doesn't need to be beaten.
Alternate Universe Human Kite begins this phase with only 1 HP, but his first action will throw up a shield to give himself an extra 180 health. Despite this, you should focus on Aunt Sheila; if her nephew is or son are hurt before she falls, she'll flip out and gain a free turn after every member of Coon and Friends makes their move. She has a basic melee attack and a charging move to hit multiple targets; as with her nephew, spacing your characters can help minimize the damage she inflicts per turn. On your turn, hit Sheila with whatever attacks you like; Human Kite might attempt to shield her, but a continuous barrage should overwhelm the shields. Once Sheila falls, return your attention to Alternate Universe Human Kite; even with his shield, he won't last long. Note, you do not need to defeat Human Kite to win.
Return the Kite
After the fight, you will need to fetch Alternate Universe Human Kite's kite from the tree. This is when you’ll learn a new Buddy Power, Fartkour. Whenever you see a pinwheel, you can now enter Inspection Mode and call upon The Human Kite to reach high-up places otherwise inaccessible.
Now continue to you next mission: Microaggression Academy.
