So, this is how I see these people if MHA was in a fantasy kind of thing 

So, obviously, Bakugou would be a dragon. I think he'd have big red dragon wings sprouting out of his back, with the fantasy look 

This look 

Koy: Heh...there's a Kay on his shoulder. 

Author-Chan: Huh? *looks at the picture* Oh hey, there it is. Probably for Katsuki.

Bakugou: Obviously! 

Koy: Yes...but we could pretend-

Bakugou: Stop! 

Author-Chan: Ohhh! Hehehehe~ 

Bakugou: Just continue! 

Author-Chan: Okay, okay

Next, I see Kirishima being a werewolf, Like I dunno why, but I just think it suits him

And he's in Mei's pack, making her a werewolf too. 

Mei: ...Meh. Could've gone with my backstory and made me a demon-

Author-Chan: Nuu.

And that is because Koy, you're human, unfortunately.

Koy: Dang.

Author-Chan: BUT! You were shunned out by your village, thrown to the wolves (hehe), and instead of killing you, they brought you into their pack, the second alpha of the pack. Mei being the alpha. 

Koy: Cool. So are...Kay and I not siblings in this world?

Author-Chan: No. And that is because she's a vampire hybrid. 

Kay: Like...human and a vampire?

Author-Chan: Nope! You are mixed with another creature, but only I know this, and I will only know this...but there are different prophecies about a vampire hybrid, there's a dragon one, a werewolf one, a demon one-

Bakugou: Is this just so you can ship her with as many people as possible? 

Author-Chan: NO! ...Maybe, but she does end up with you, but I won't explain the prophecies. 

Bakugou: Grr...

Kay: So...why am I an unknown hybrid? 

Author-Chan: Well, mother vampire, mother died a long time ago when you were a baby, and dad left. 

Kay: Oh...

Author-Chan: Next...Hmm, what would be good for Deku...OO! Wizard! 

Deku: You think? That's wonderful! 

Bakugou: It's because you're a damn nerd! 

Author-Chan: Do your arguing later, we cannot get distracted! 

Ummm...Ommi is a pirate, and HAwks is an angel. 

Ommi: Pfft- *covers her mouth*

Hawks: Hey, I can be angelic. 

Ommi: Yeah, keep telling yourself that. 

Author-Chan: And on that note, Kashi is also an angel. 

Yes, I am putting two friend oc's that are with Koy, and yes...they shall fight here and there. 

Hehehehehehe

Koy: ...Why is it always me...

Author-Chan: What? You got a powerful and beautiful werewolf alpha lady, and a gorgeous, angel man who watches over you. 

Kashi: Heh, I don't know about gorgeous, but thank you.

Koy: Mhm...and how deadly are their fights? 

Author-Chan: ....MOVING ON! 

Uhh...Mina is a demon. 

Mina: Makes sense, no complaints.

Author-Chan: Sero is a...hang on *goes to Google* Spider humanoid... Arachne, that's what Sero is. 

Or, spider humanoid, because I didn't know the name. 

Sero: It's because of my tape, huh? 

Author-Chan: Yup! 

Sero: *Shrugs* Not a problem. 

Denki: What am I?! 

Author-Chan: You are another dragon. A lighting dragon! You have yellow wings. 

Denki: Oooo! That sounds awesome! 

Bakugou: Tch, I'm still the top, the alpha! 

Author-Chan: You're a dragon...however, you're a dragon prince. 

Bakugou: I'll take what I can get. 

Author-Chan: Now...Shigaraki is also a pirate, and Amisho is a siren.

Amisho: Cliche. 

Shigaraki: Why am I a pirate? 

Author-Chan: What? I think that would be cool, besides you're the leader of the LoV, so that's your crew. Toga is a vampire pirate, and Dabi is a zombie pirate. 

Dabi: Of course, I'm a damn zombie...

Amisho: You are a walking corpse. 

Dabi: And you're a fish. 

Amisho: Yeah. I can-

Author-Chan: NOT NOW!

*ahem*

Now, Tamaki is going to be a vampire, a very timid and kind vampire. As he's the best boy. *pats Tamaki's head*

Tamaki: *blushes gently* T-thank you...

Hizani: Am I a vampire? Or a demon? 

Author-Chan: Neither...you're um...heh, a bunny kin...

Hizani: ...A what? 

Author-Chan: So, you're mostly human, but got the bunny ears and tail-

Koy: Why not make her a bunny kin demon mix? 

Author-Chan: That's...a great idea! So you'll be a bunny kin demon hybrid! 

Hizani: ...Am I bunny because-

Author-Chan: Yes.
Anyways, 

I'll do a couple more...Aizawa is gonna be...Hmm...he could be a werewolf, but a merman would be cool...but I don't think that would fit him...

I dunno, I'll come back to Aizawa later. 

Aizawa: No, pick now. 

Author-Chan: Ugghhh, fine Dadzawa -3-

Hmm...I guess I'll go werewolf because I can't think of anything else. 

Let's see...Shinsou is a... *goes to Google again* ...a naga! 

Shinsou: ...A snake person? Why? 

Author-Chan: Trussst...in meeee~ 

Shinsou: What? 

Author-Chan: The Jungle Book...have you not...seen it?

Shinsou: Not really. 

Author-Chan: ... *grabs Shinsou, taking him to watch Jungle Book* 

Koy: Did...she just leave us? 

Denki: Yep! What should we do? 

Kirishima: Hmm...We could go do something manly! 

Aizawa: I'm going to nap. 

Tamaki: I-I wanna go home...

Hizani: I want a pretzel.
