The test is fast. Walker offers himself as a test subject. He will be using the Obliterator suit. One punch and Walker is at the other end of the big testing room, a bit confused, although he has only some bruises. It is obvious normal weapons won't be of any use, however the same alloy used in the Obliterator could be used. But if you had Strenium it would be even better, but as far as you know, you need very special conditions to forge Strenium into weapons (the only ones you know of are two shields, and they were forged in a space station). You have also heard of Optimum and Zynex, two metals that the Europeans are testing and could be even above Strenium quality, or at least near it.
Meanwhile, the three teams depart. As they get to the different places you start getting messages.
"Sir, this is New York Task Force. There are metahumans here. They are in the Madison Square Garden. Descriptions by the local forces are not very accurate, but there seems to be several lizardlike mutants and a young woman fighting them, a local superhero called Harlequeen. The metahumans are all inside and the police has established a security perimeter."
"Sir this LA Task Force. There has been an attack on a small antique shop. The attacker took a mask and destroyed the shop. He is now on the move, teleporting randomly through the city. He seems to have little control over his powers."
"Sir, this San Francisco Task Force. There has been some fighting between two metahumans. Witnesses say the looked like if they had come out from an old Chinese kung fu movie, but with broken doors and 3 meter high jumps. We don't know where they are now, or if they are still fighting."
