This is what started it all, the origin story, the curtian-riser, The First Act.
It was a normal day in Kanto and Ash, Pikachu and Misty were walking on the street when suddenly, Team Rocket appeared after a big puff a smoke. Before they could say anything however, Ash said "You two AGAIN?? I have had ENOUGH of you!" Then Jessie replied "Ok, If you can't stand us, you can leave." She laid a smoke bomb and it exploded. When the smoke dissapeared, Ash, Misty and Pikachu were gone.
In the Pride Lands, Simba and Kovu were hunting for zerbas when a puff of smoke appeared in the sky, then Ash(who had gone under some transfomation), Misty and Pikachu fell and landed in Hakuna Matta. Simba said "Kovu, you stay and hunt the zebra, I'll go and see what's going on over there." Later in Hakuna Matta, Timon heard a big splash and went to check it out. When he saw Simba, he said "Hey, Simba boy! What are YOU doing here? Are you here to see what fell in the pool, too?" "Yep." replied Simba, who then saw a paw rise out of the water. He then said "Oh my GOSH! Timon, Pumbaa, pull him out of the water." Once they pulled Ash, Pikachu and Misty out of the water, Ash woke up and said "What happened?" Then Misty woke up and asked "Hey, Ash, why do look different?" Ash looked at himself and 3 seconds later, he freaked out! Then, he calmed down and Misty introduced herself along with PikaChu and Ash. Then Timon said "Want some grub?" Ash replied "No way am I eating Metapods or Caterpies." Timon was confused. "Metapods??? Caterpies????? WHAT TYPE OF GRUB IS THAT?!?!?!?!?!?!?!?!?!"
