Normally, if you kill the episode 1 boss, the ending cinematic for episode 1 will begin playing. This quick effect allows you to turn the episode 1 boss into a Mini-Boss (so you can kill him without the cinematic).
Place the episode 1 boss wherever you want. Give him a palette value of 21. That's all!
To spawn the episode 1 Mini-Boss, place an R[2630,Channel]
where you want the Mini-Boss to spawn and give it a palette value of 21. Use a trigger and give it the same Channel to activate the Respawn sprite.
