Back in the World Tour/Soul Search story there was actually a comic where the Chupacabra was supposed to show up, but it was near the end of the arc and by that time I was super antsy about wrapping up the storyline and just getting the guys home.
So, I’ve been wanting to introduce him for a while, but I didn’t want to just have him show up for no reason at all like he was just one of the monster’s friends from out of town or something…
By having him be yet another stereotypical character I was able to have his introduction be part of this moving arc.
Also, by delaying his debut I ended up getting a far better looking character design for him, in my opinion.
And yes, I realize that John is effectively saying “The The” in his second balloon. I thought it was funny by having THE “El Chupacabra”. I know “el” in Spanish means “the”, but it’s like his name inherited the article.
