Well I think Dash is very proud of superspeed. He gets really excited to use it whenever he can. Like when Elastigirl told him “I want you to run as fast as you can” you can tell he loves being told this. He is competitive and full of energy so, as said before, superspeed suits him.
I don’t think he’d be jealous of Violet’s powers themselves, but I think he might get jealous of the fact that she has two of them.
Being a young, competitive boy, I think he would appreciate the powers he has. I don’t think there’s any jealousy. I think the only thing Dash would be jealous about is never being put in charge of anything.
I don’t really see why he would be jealous.
Me niether.
The superpowers that each of the family members has in the film are designed to fit their characters perfectly. Mr Incredible feels the need to be strong and protect his family (as a father) and others (as a super) whereas Elastigirl almost represents the mother who has to do everything and needs to “stretch” a little to make sure things fall into place. Violet is a shy teenage girl who’s only just realising her full potential, Dash is slightly hyper and competitive like many young boys, and Jack Jack is a baby who’s constantly changing with so many possibilities as to what he can become. These obviously aren’t just coincidences yet the characters have been developed well enough so that you realise their powers don’t JUST fit their current state and “stereotype”, but also fit their personality. I don’t think Dash is, or would become, jealous of Violet because he enjoys his power and it suits him well.
I’m sure Dash like’s being fast, He seem’s to like it and not care for his sisters powers.
Being fast sure does have it’s advantages.
Dash loves being fast it makes him a beast at sports. He isn’t jealous of Violet.
Besides, hiding is weak and feminine. 
^ You stole my post 
Oh, did I? Well, geniuses think alike, y’know. 
haha, just kidding. You’re way smarter than me.
Anyone think Bob is jealous of Helen? Do he could grab a cheeseburger without having to get uo if he had them. 
I don’t see Bob being Jealous because look at his lair. He is praised as a favorite super by himself and his strength.
Even if he woulden’t have to get off the chair.
But if never got out of his chair, wouldn’t he become lazy and gain more than the 50 pounds as stated in the movie?
I mean before the movie.
I really don’t think it’s plausible that any member of the family is jealous of the other’s power.
I wonder what the Bob’s parent’s powers were and Helens.
I always wonder about their parents in general.
They needed more of a backstory. Where they think supers got their powers, Bob and Helen’s parent’s and childhoods.
