"Wait!" You say.
"Why?" The naive 10' tall Silver asks?
"The process that allowed gave me my transformation power also allowed me to change other aspects of my body," you respond. "I kind of want wings like you." Silver just blushes.
"Thanks Pops!" he responds.
"Okay, wings." You say. Sure enough, feathery wings like what Silver has grow from your back. "Yes, now lets go for a test flight." You flap your wings, and you lift off the ground, Silver following suit. Then you and your son fly around, eventually finding out you can fly pretty fucking fast. Then, you and Silver touch back down in a forest. You decide that terrorizing the stadium can wait another day. You instead try to see just how strong you and your son are. First, you test how durable your muscles are, seeing how you already know about Silver and his being bulletproof. So, you ask him to punch you as hard as he can in your 10 pack abs. He obliges, and he punches. It felt like someone throwing an acorn at your abs. You realize that in your current form, you are also bulletproof. You remember that for later. Then,, you see how much you can lift. You walk over to a giant boulder, probably weighing 100 tons. You pick it up with one hand like it was a piece of paper. Then, you decide to play a game. You throw the boulder to Silver, who catches it in one hand. He seems to be as strong as you. You then play catch the boulder for a while. However, you really want to find out how strong you and Silver were.
"I have an idea!" Silver exclaims. "I know how to find out how much we can lift!"
"How?" You ask.
"We go to the train yard. All of the cars are around 100 tons there. We just see how many of them we can lift at once."
"Silver, you are a genius."
You and Silver fly over to the train yard, where hundreds of abandoned train cars are lying. "Perfect," you squeal with joy. You get 100 cars together somehow, and try to bench it. After one rep, you realize that this is your max. Then you let Silver have a go. He too could only do one rep. "O.K, so both of our max lifts in this form are 10,000 tons. Not bad. Now, let's have some fun."
