My adventure idea

[Ameraaaaaa]

So starfinder all players are level 20 and the player's find an enemy ship after they beet itthey see an enemy making a magnetic field filled with stuff then the fight begins 1st the player ship is destroyed and the player's end up landing in a abandoned military base in said place the enemy follow on foot
1st encounter the blob in power armor and fire star the blob has he's own gravity and a mace he drags the pcs in while fire star aoes them there's more details but when i eidted it in for some reason they become lost but here they are
If blob is killed fire star will try to escape and come back later
If fire star is killed then the blob will stomp the ground and make earthquakes because since now it won't harm he's ally
Now encounter 2 in the underwater where toad man and piranhas and sharks under he's control
Encounter 3 in a normal looking room that's actually illusioned to look that way and is filled with traps because of mastermind im not sure what else to do here
Encounter 4 they find quick sliver and scarlet witch qs uses he's speed while sw forces the player's to roll tyice and pick the worst 1 while sc and qs get the same except they pick the better 1 also sge blasts the 1 pc at the same time
What you think so far

The final fight magneto himself fights
1st he puts up a sheld that can only be beet by sonic weapons or magic after he gets hurt he romoves the sheld and then controls the environment after being hurt a few more times he takes the metal and covers himself in a metal golim after that's destroyed he controls the iron and copper in he's body to become faster stronger durable and a greater control over he's body then after dieing he uses the last of he's might to damage the base to the point where it will blow up in a few rounds and there's only 1 escape pod
Any help

What do you want help with? Designing stat blocks? More ideas? General advice?

• Encounter 1: Give Fire Star a jetpack so the Blob can just earthquake with impunity.
  
• Encounter 2: You should have an octopus or squid instead of pirahnna, those fish just are too hard to care for in the kind of environment where you also have sharks. Maybe an electric eel, but that would hurt the Toad too.
  I think someone once asked what happens to a toad that gets struck by lightning...
  
• Encounter 3. Sounds a bit blah. It's fine to have traps and such, but there really needs to be action. A tactical battle with squares trapped, possibly with a repulsor field that ejects people outside or knocks them into walls. Maybe a giant robotic turtle with turrets on it. Or possibly the Rhino just comes charging through with Improved Overrun and Bullrush and knocks anyone who doesn't get out of the way into traps or hazards.
  How do you stop the Rhino from charging? Take away his credit card...
  
• Encounter 4: Give Quicksilver and Scarlet Witch a high-tech bracer that you need to use both of to open the next door into Magneto's room. They function as bracers of armor or something, but what isn't known is that they are also shock bracers that Magneto can activate with his control of magnetics, so if the PCs put them on to open the door and don't take them off before facing Magneto, he activates them. They deal like 20 electricity per round (Fort for half) and can't be taken off without a Disable Device check or smashing them, which makes them explode for 50 electrical damage (Reflex for half).
  
• Encounter Magneto: After the metal exo-skeleton, Magneto should raise the entire metal floor of the base, which is like a 100 foot plate of metal sections. It should rise about 10 feet per round. If you want the floor to be in sections, you can have parts of it drop out, leaving holes. PCs should have a way to rejoin the fight if the fall off (maybe Fire Star's jet pack). Then if they beat Magneto, they also plummet to the ground, and all the metal debris sets off the base self-destruct.
