(Warning - the following contains GIANT, HULKING SPOILERS for the rest of Agents of S.H.I.E.L.D. season 3, and potentially beyond. Proceed with whatever level of caution your innate sense of SPOILER-aversion suggests is wise...)
Now, Grant Ward has arguably had a hard time of it over the course of two-and-a-half seasons of Marvel's Agents of S.H.I.E.L.D. - what with that whole 'turning out to be a double agent' thing, and the constant series of potentially fatal scenarios that it has subsequently put him in. The only compensation (other than, y'know, getting to start his own business, which is always a rewarding endeavor) is that it's long seemed likely that he's going to eventually get to turn into a major comic-book supervillain of some sort.
And now, it seems, that day is finally - finally - set to arrive. That's right...
We Finally Know Which Supervillain Grant Ward is Going to Turn Into
Before we get into exactly who that is, though, two things should be made abundantly clear:
1) The following is potentially HUGELY SPOILER-IFIC, so proceed with caution.
2) There's a pretty good chance that you're about to find out that Ward won't be turning into the supervillain you were hoping for, so it's likely prudent to also proceed with steeled emotions and the like.
Grant Ward is Going to Turn Out To Be...
...the parasite-formed villain known as Hive.
That, at least, is what the show's star, Elizabeth Henstridge, aka Agent Simmons, recently revealed at the 2016 Wizard World Convention, noting that:
"Watching him [Brett Dalton, aka Grant Ward] play Hive is interesting. He has the memories of the people he has killed."
Which, it seems, pretty much conclusively reveals that Ward will, at some point in the near future, be transforming into the comic-book villain Hive (at least for a little while).
Who the Heck is Hive, Though?
Well, in the comic-books at least, Hive isn't technically a person at all. Instead, it's a vast number of genetically-engineered parasites developed by Hydra to physically embody the organization's ideals.
In the comics, an unnamed Hydra agent was offered up to the parasites as a host, creating a monstrous being defined by a collective, Hydra-oriented will.
Which, yes, is just as terrifying as it sounds - and suggests we're going to see Ward try out a brand new parasite-based concoction in the series sometime after it returns on March 8.
With, y'know, horrifying (and likely entertaining) results...
