When GotG 2 drops in 2017 there will be additional characters appearing both as villains and new team members.
Who do you think will be represented and who do you want to show up?
Here's my short list:Adam Warlock
It has already been established that his cocoon is in the Collector's menagerie and he is a long time Thanos adversary so he's a pretty obvious choice.Moondragon
The daughter of Drax the Destroyer and associate of the Guardians. Also has lots of history with Thanos.Star Fox
The brother of Thanos and an Avenger to boot. Plus, someone has to be Peter Quill's father, who better than the Lothario of the spaceways?Nova
The Nova Corps figured prominently in the first movie, it's conceivable that a Centurion could be assigned to the GotG. Richard Rider, perhaps?Quasar
A long shot but eminently possible. Either the Wendall Vaughn version or the Phylla-Vell incarnation could be worked in.BugReal
long shot. This would be a fantastic way to introduce the Microverse and he would fit in well with the comedy aspect. >tik<
As far as villains go I think these would be intriguing choices:The Blood Brothers
Known lackeys of Thanos.Korvac
Maybe a little too powerful to be a thrall of Thanos but Michael Korvac and his minions have encountered the Guardians before.Magus
The evil future self of Adam Warlock. If Adam appears it's not too much of a stretch to envision the Magus around.Super-Skrull
The Kree have been established, why not the Skrull's? Who better than Kl'rt to represent this warrior race?The Elders of the Universe
We already have the Collector, how about seeing his cosmic siblings like the Grandmaster, Contemplator, Champion, Gardener, Runner, etc.?
Who else would you like to see?
