The stated reason for various forms from Jeff Davis is that all Alphas have the ability to go full monster like the Alpha in season one.

Jeff says they chose not to do it with Derek. Hoechlin later said that they wanted to show the character's humanity. And the bottom line in the real world is that they can only afford so much CGI each season and the Kanima sucked it all up in Season 2 while the Deer, the birds and some of the other Darach stuff sucked it up in 3(a).

So - as far as the canon is concerned - all Alphas have the potential to become beast-like but it's a choice.

None of the Alpha's in the mall went "beast mode" they all stayed mostly human so I don't think that is a good indicator of potential.

Scott's shadow self is a beast. I've heard the word thrown around quite a bit in the promo's for More Bad Than Good so I think you are right in that we're about to find out more.
