User blog comment:Godechaud/Teen Wolf Werewolves - Always evolving Art to the detriment of good story telling?/@comment-26879545-20160406214224

Venom isn't a werewolf, but neither are Hulk and Abomination. None of them have anything to do with werewolves, but the comparison is still there.

Jeff was just saying that the Beast is similar to Venom in the sense that both of their "suits" cover them. Whereas Hulk and Abomination actually change and shapeshift, Venom's symbiote-formed outfit envelops him just like the shadows did to the Beast.

Anyway, the reason the other Alphas never did the s1 Alpha Form was addressed in an interview. All Alphas have access to that Monster form; it's just that the cost of the CGI for them was heavy on the budget.

This part is my speculation/two cents:

It was okay for s1 because they didn't have a lot to lose. They were just starting, the "main" cast was small, and it was set in... like three or four areas tops. Now, we see more main characters, more locations, more effects, etc. If they had to cut the Alpha form in order to give us more creatures, more effects, better make-up, etc., then so be it.
