Corium Suit ($40)

Ok here's a cool one. It's a hazmat suit to turn one of your characters into a superhero.

This guy invented a hazmat suit that can withstand Corium https://youtu.be/hIWu8rbWLGo 
TLDR That's the radioactive stuff you get after a nuclear meltdown, like the Elephant Foot at Chernobyl

So it turns out the corium itself was also intertwined with all the spirits of death in a nuclear power disaster, like thousands died from this meltdown here.
And when it realized the guy in the suit could approach it without dying, it started to speak to him telepathically. The victims of the disaster wanted revenge - because the power plant was sabotaged. The corium was alive with a thirst for vengeance!

So it agreed to grant it's powers to hazmat suit dude and now he has sick powers, and he can do everything corium does, without the life destroying radioactivity. He can melt through buildings, morph the melted mass living on his suit into weapons or armor, even throw it as projectiles and it will crawl back onto the suit. It can heat up to half the heat of the sun. It would destroy the suit so only if he uses projectiles.

What adventures will he have on his quest to find the saboteurs?
