The Fusion Factor

Sneek Peak
Max: This is it.

Ash: Brock, get our friend back.

May: (possesed) Not so fast!

Brock: What?

May: (possesed) I use Super Polymerization. By trashing out 10 items I have, I can fuse 2 Pokemon together! Like Blazekien and your Zubat leaving Onix left for you! Together they form Blazifiend!

Ash: No. That fiend is too powerful!

May: (possesed) And the best part is when its called out, your Onix is forced to battle with a random move. Go now. Use Flare Storm!

Explosion

May: (possesed) What are you doing?! You have no Pokemon left! No! Blazifiend!

Brock: Now the effect of what Onix was holding goes off. Because he fainted, your Blazifiend took damage from double the damage he took.

Explosion

May: (possesed) RRRRRRrrrrrrrraaaaaaaaaaaaaaaahhhhhhhhhhhhhhhhhhhhhhhhhh!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
