Based on what we know Jack-Jack is capable of, what do you think he’ll be like at, oh,
let’s say, age 5?
Will the rest of the family have discovered his powers by then?
Will he be an
out-of-control child?
How will he get along with his siblings?
Will he have more hair?
~~=oP
I’m
predicting a pic PV? 
In my opinion yea, Jack-Jack would’ve blown his cover the next time he got upset’
seeing that they weren’t “activated” until his babysitter encounter. 
You think normal 5
year olds are crazy, Jack-Jack’s gonna be off the walls! 
I could see Dash definetly taking advantage of the
word “brother” and turning it into “apprentice” Teaching Jack-Jack the best ways to
annoy their sister even teaming up time to time. 
Yes! Dash and Jack-Jack shall form an annoying little brother
duo stronger than any force of evil known to big sisters everywhere! Mwahahaha! 
In time.

You already have one! =P
But it stinks! =P

I can imagine that happening! Poor Vi! 
And Bob will be very proud and
training his son to be a real superhero in no time.
I’m am
theroizing those questions right now.
discovered his powers. If he ignited into flames at the age of five, of course he will tell his family, like all
kids do when they feel sick or wierd.
2) His powers, though seemingly in control, seem kinda random. I
hypothize he will be an out of control child.
3) Like most little siblings, some get along and some have
trouble getting along. I think iit will be a combination of both.
4) Yes, he will have more hair. If the fire
won’t burn it up, he will have more hair.
