Lemme explain...

There are different versions of Rusty depending on who she speaks with.

For example with @wolfofsteel he is a Steeljaw that is under parole and therefore while the events of the first season effect that the seasons after do not. SO he is a “good wolf” and thus Rusty knows this and that he would not do the events in the seasons thereafter.

But when she is with @themoosemafia, @youthinkyoucantakeusallon and @abouttogetratherdark I’m under the impression they follow canon more closely and while there are some things that are divergent from it (ie, wendigo and scarab and hoofs family just to name a few) I feel that in that world it is more likely that it follows canon closer just that Chopshop actually is in the picture more.

But while that verse and the one with @strangexbedfellows and @klepto-corvidae are similar and sometimes seem to overlap there is a little difference. Rusty in this case was left before the second season and she stayed with Filch, Nightstrike, Pseudo and Pilfer.

However all of them end up the same way with her taking over the old mill that Steeljaw and the pack had in the first season. It’s her place now and after the incident in season two the humans left it alone because they were sick of all the damage. There’s even a sign outside that states “Do not enter!” in her handwriting in big bold red letters. The Chompazoids helped a lot in clearing the place. XD

And if in fact Denny Clay is the average 6 feet in height then Fixit is closer to 4-4.5 feet tall. Meaning his son Russel is around 5 feet tall.

Rusty is like a sleeker more compact version of Steel. That about the best explanation I can think of. She’s taller, has longer limbs and her armor is centralized around her torso. Elbows to knees she has the bulk of her rust red / metallic orange armor. The rest of the limbs are covered in a light weight but dense black metal matching her dark protoform underneath.

Her sensitive muzzle is also longer than his and can create those feral wolf expressions better. Her ears at just as tall but rounded instead of pointed. 

In essence Steeljaw is more of a warrior/grappler where as her frame is built for being flexible and agile. Despite that she can still hold her Sire’s Claymore Blade with little effort.

Her coloration accurately mimics a maned wolf including the black mane that lifts and lowers with her aggression. Since growing she has lost most of her biolights. A strip on each shoulder, one on either side of her neck and two on her lower back.

Her alt-mode folds neatly into her root mode, the doors hiding under her chassis that also bears the front window. Her stomach showing off the headlights on either side. Two wheels are tucked into her shoulders the other two are in her heels.
