Simpson and Stitch

(CROSSOVER BETWEEN POKEMON AND LILO AND STITCH)
What if stitch escaped to the pokemon world instead,where his destructive habits could be allowed?
What if all of the experiments (i know nothing about most of them) came to the pokemon world aswell?
Join Simpson (my oc) Jumba,Pleakley,Ash and his Unova friends,on an adventure.
I dont own Pokemon or Lilo and Stitch.
Also,no,my oc does not look like that person in the thumbnail,i look like the black avatar choice from usum.
