What threat is he running from?

The very man who had his mother.

You mean humans in general, or literally the same man who took Dupe's mother?

Either way, OH NO!!!

When I first read the info, I was thinking that Dupe was running from zombies since you said this picture was an homage to Resident Evil's poster. Or perhaps the Umbrella Corporation.

I can't take it anymore! I have to do an rp of this! Feel free to join in if you want.

Jeff walks out of a sandwich shop with a large sub sandwich in his hands. Another stuffed under his coat which he intended for Duplex. As he walked around the corner, he noticed said dog/fox hybrid running toward him with a look of fear on his face.

jeff: Dupe? What's the matter? Who are you running from?

I'll just write this next part for you.

Dupe: Dog catchers! (Runs past the wizard)

Jeff: What?! (Turns to see the familiar white van) Ah bloody hell! Alright hang on! (Runs toward the dox and picks him up in his arms) Levi Corpus! (As soon as Jeff recited the incantation, he suddenly levitated into the air while still holding onto the canine who then immediately turned to wrap his forelegs around the wizard's neck out of fear of falling)

Dupe: Damn it, Jeff! You know I hate flying!

Jeff: I've told you before, Dupe. It's not flying, It's levitating!

Dupe: What's the frigging difference?

Jeff: (Rolls his eyes as he continues explaining) True flight has little to no assistance involved. Levitation is usually only possible with magical assistance.

Eventually, our two heroes land on the roof of a building where they hide out from the dog catchers' van.

You can continue from here if you'd like to.

They're no ordinary dog Catchers. They're killers and any strong breed they find they will use for dog sports

That was exactly the plot twist I was gonna use in our Roselda's Fate storyline! Two great minds think alike!

After Jeff and Dupe levitated away, the dog catchers lose sight of our heroes.

Dog Catcher 1: Shit! Lost it!

Dog Catcher 2: It looked pretty strong too. How the hell did that guy disappear with it like that?

The two dog catchers drive right by the very building the two were hiding on top of.

Jeff: (Watching from the roof) I think they're gone.

Dupe: (Panting and sighing) Thanks for the save.

Jeff: Don't mention it. How'd they even find you?

Your turn

Alright, I'm just going to write my ending to this rp. Let me know what you think and maybe write your version of the ending too.

Dupe: Well, I was just scrounging back alleys as usual when I heard an engine. Then, I heard talking. Next thing I knew, these big hands tried to grab me by the throat! I dodged out of the way and looked back to see the same Mafia dog catching thugs than took my mother away! I normally would have tried to fight back until they tried to shoot me with tranquilizer guns! I got so scared that I had no other choice but to run! They chased me down nonstop throughout the neighborhood in their van trying to shoot me with those darts. That's when I ran into you!

Jeff: Man. Those guys really want you bad if they'll shoot tranquilizer darts all over town! You OK? You didn't get hit, did you?

Dupe: (Looks over himself) No. I'm fine.

Jeff: Good. (Takes out the uneaten sandwich from under his coat; Unwraps it and places it in front of the dox) Here, this was going to be lunch, but I guess it's dinner now since we were running from bad guys all day.

Dupe: Wow! Thanks, pal! (Starts eating the sandwich)

Jeff pulls out his own sandwich and continues eating it. As soon as the wizard and canine finished eating, they looked at each other, then the stars.

Dupe: Hey, Jeff?

Jeff: Yeah?

Dupe: Why do you think these guys took my mom? I mean, she was a fighter but not one who would fight to entertain sadists.

Jeff: You know what? I really don't know. Maybe their boss just really loves torturing animals. If only we can find their current hideout. We could just wipe them out. Unfortunately they're muggles. And I swore an oath to never harm or kill muggles when I first became a sorcerer.

Dupe: Not even the bad ones?

Jeff: Not even the bad ones. Not even if I wanted to. Now, if they were warlocks or demons on the other hand, then there would be NO MERCY!

Dupe: (Sighs) If only.

Meanwhile, in another part of town, the 2 dog catchers were parked near a junkyard.

Dog Catcher 2: Damn! We lost that dog! The boss is not gonna be happy we lost a new potential gladiator!

Dog Catcher 1: He said he specifically wanted that one dog/fox mix! He said it was rare and strong! Stronger than even the largest pure bred fighting dogs in the world.

Dog Catcher 2: Didn't look that strong at first glance, but damn was it fast! I swear it was literally like trying to catch smoke with your bare hands!

Dog Catcher 1: We'll get it. And if it turns out to be as powerful as the boss said, we'll make a fortune in the Beast Ring! (Laughs evilly)

OK, I've got to add a song to this, The song I just thought of just fits this perfectly!

Jeff: (Singing) I walk along the avenue,
I never thought I'd meet a girl like you
Meet a girl like you.

Dupe: (Singing with Jeff) With auburn hair and tawny eyes,
The kind of eyes that hypnotize me through
Hypnotize me through.

Both: And I ran,
I ran so far away.

I just ran
I ran all night and day
Couldn't get away.

Dupe: A cloud appears above your head,
A beam of light comes shining down on you
Shining down on you

Jeff: The cloud is moving nearer still,
Aurora Borealis comes in view
Aurora comes in view.

Both: And I ran
I ran so far away

I just ran
I ran all night and day
Couldn't get away

Jeff: Reached out a hand to touch your face,
You're slowly disappearing from my view
Disappearing from my view.

Dupe: Reached out a hand to try again,
I'm floating in a beam of light with you
A beam of light with you

Both: And I ran
I ran so far away

I just ran
I ran all night and day

And I ran
I ran so far away
I just ran
I couldn't get away.

I Ran by A Flock of Seagulls
Such a cool song!

Well, life is hard sometimes.

For others, it's extremely hard.
