Hee hee hee.
Pyrepower here! Mr. Big is still away. So I'm writing the guide still!
Today is our ENTIRELY HYPOTHETICAL methods for capturing two hunky superhero boys: The Philly Fleetfoot and Rail Runner. By sheer coincidence both are speedsters, so we will be using the same tactics against both.
First, we consider weaknesses. What are they observed to be weak against? Well, neither can get out of a really deep pit, so we have something. We need a pit! What do we have for powers? Well let's say fire manipulation. Rock would be really tough to get out of, and the melting point of most silicates is about 1200 degrees Celsius. Super awesome trivia note! The Space Shuttle's tiles can absorb about this much heat without burning your hand.
Next, test that you can produce that much heat by obtaining a sample of rock and burning it with your powers. If this test fails, think of a new plan.
Let's assume your test is successful. Bring along a stopwatch so you can tell how long it takes to slag the sample. Divide that time by the volume of the sample, then multiply by the volume of the pit you want to dig. Assume 20' by 20' by 30' deep.
Next, you need a spot where you can dig this pit uninterrupted. Check a map of your area and find some good ambush points. Like an abandoned subway tunnel. Your digging puts out an awful lot of heat and light.
You want a hostage. Obtain one, tie him up, then put them at the bottom of the pit. They must be tied up securely so they can't escape. Put a rope ladder at the top of the pit. When your hero shows up, they'll see the ladder and go "cool, a ladder" and try to unfurl it to the bottom. They'll see that the hostage is tied up, and figure out that they have to go down and help him out. So your rope ladder should be set up to give way the second they get down there. For example, radio-controlled explosive bolts in the rock.
At this point, you should have your very own superhero. Now you need to make an appearance. Tell them that if they untie the hostage, you'll lower a rope and pull him up as long as the hero stays in the hole. Escort the hostage out (blindfolded so he can't lead the cops back to you). That gives the hero some time to start feeling depressed and stuff, so when you show up he'll be more willing to go along with whatever, y'know, you happen to think up next.
I think it'll work!
Hee hee hee.
