After seeing a few episodes of Candace in action, I realized she had a few traits that match up with Jas.
The most obvious one is they're both overbearing sisters with younger brothers.
Although Jas, while annoying, isn't anywhere near Candace's level of obsession (then again, who is?)
I read some notes that suggest Candace's obsession comes from a desire to protect her brothers.
Jas has always been overprotective of Danny, since their parents' ineptitude put most of the responsibility of keeping him safe from their dangerous inventions onto her.
And they're both skilled at the arts of physical unarmed combat.
And apparently, they're both fond of launcher weapons:

And I find it interesting that their surnames both start with F.
As an aside, why does Candace's launcher have a Fireside Girls logo on it?
Since when do girl scout groups specialize in weapons manufacturing?
