it also has another file: Blackmask's plan.
Step 1: Make them hate you, annoy them, attack them or whatever you want, but they must hate you.
Step 2: spend the rest of your life creating a machine to travel across time, no matter how, you have to do it.
Step 3: When they are about to activate the Meta-nav use your mind control to stop them, from the future I will open a time portal to that location, push them to the portal and disappear.
Step 4: Prepare yourself, this is about to trick Lavos, not to have fun. In the future, one day, they will come, be prepared, remember, they have to kill you.
Step 5: force them to do the underground way, there is an elevator there to carry them to the real world, it will be destroyed by Lavos, so you have to find a way to carry this place to the real world, after Lavos attack the world will be unstable, use that.
Step 6: they will discover the truth and Lavos will be unable to notice it, when they arrive to the M-build ask them to kill you in the present, Lavos will think what I failed, and you will be free to help them.
