“And just how would you know if you’re actually doing anything, Sue, if you can’t see it?” Johnny asked with an arch of his eyebrow as he considers his sister. He took a long deep drink from his soda before he set it down, and then he stood up from the chair he was in. He then concentrated on his own powers and transformed himself into the Human Torch.
“Try and put this out.” He said as he held a hand up. A flaming pigeon (hey, they were in New York) then emerged from his hand and moved to land on the ground right in front of Sue. The construct would just stand there without moving, though. Of course, it was taking all of his concentration to keep that construct active in a way that neither it nor he was damaging the floor. But even then, his gifts required oxygen to be active, and her forcefields were capable of being airtight.
