WORD?!?! I am Groot Venom
The following contains spoilers, but its also contains some pretty neat speculation!
This was hinted at a few months ago when people read Previews and saw the synopsis of the issue- In the new Guardians of the Galaxy The Venom symbiote is brought into the story and wouldn’t you believe it? The case broke and got a hold of Groot.
Based on the popularity of the Venom / Deadpool one-off – this issue, Guardians of the Galaxy #21 and the next issue Guardians of the Galaxy #22 are not to be slept on (even if it is just for the short term flippery!!!)
