Because people have been "complaining" of "too many pictures," which is ridiculous by the way, I have moved the Tale of Blue (i.e. how it works) to the following post.
So for those who are interested in how I did all of my triggers and how I got stuff to work I give you:
The Tale of Blue

He spawns falling into a teleporter where he grabs the camo.

Shotgun boxes interior

Shotgun boxes exterior

After destroying the pallets, a new pallet spawns, and opens the teleporter.

Have no mercy.

When he respawns, he drops onto a mancannon, which hits him against some explosives, and he teleports out.

The fusion coils are then launched, and explode.

Which spawns one on the next teleporter, blowing up the fusion coils already placed.

I added a box that spawns after the constant explosions start, to prevent them from being constant, because that can be annoying and distracting...

Anguish.

A similar concept to the last respawn, except he destroys grav lifts this time, which open that door from before.

End results.

Final resting place.
