Actor and part-time Hulk Mark Ruffalo has been kind of all over the place lately, largely to promote his new movie Begin Again and his environmental activism -- but for better or worse, most of his public appearances have turned into advance press for Avengers: Age of Ultron.

People just can't stop asking him about it, and that was as true as ever when Ruffalo make himself available for questions in a Reddit "ask me anything" thread this week. Not only was there a whole lot of Hulk talk, but also plenty about a possible movie She-Hulk, his favorite Pokemon, and much more. Check out some of the highlights.

On how long he'd like to keep playing Bruce Banner/The Hulk:

"As long as they'll have me. I did the math, and in 3 more movies I'll be in my 50's, and I don't know if anyone wants to see a gray-haired Hulk. Maybe that's not true..."

On who he'd want to play She-Hulk in a movie:

"I think Zoe Saldana would be a great She Hulk. It'd be nice to see someone like her join the Avengers. Or someone quiet and demure like Emma Stone would be nice. But it would be up to the powers that be."

On his favorite superheroes: 

"Well, growing up, when I was little it was the Hulk and Bill Bixby's The Incredible Hulk TV show. But as I got older it was Wolverine, and I have a signed first edition of the Wolverine by Frank Miller. That's pretty cool."

On what makes him as mad as the Hulk: 

"People messing up the environment with little care of the people and living things it will effect. Climate Change denial bums me out but that is mostly people who just haven't looked too deeply into the issue or have very little regard for science. Cruelty, and selfishness upset me and greed is a major ugly quality in people. Wars also suck."

On his friendship with Iron Man himself, Robert Downey Jr.: 

"We have a really good friendship. We've known each other since before Zodiac. And he's kind of like an older brother that I wish I had. He sort of looks out for me, and I remember when the role came up in the movie, I reached out to him, I was nervous about it, I said 'I don't know if I can do this' and he said, 't's alright buddy, I gotcha.'"

On whether he prefers dinosaurs or dragons: 

"Dragons. Most def."

On his favorite Pokemon:

"Squirtle. For some reason that was the first Pokemon I got on my Game Boy, when I was playing it - they would give you 2 different ones, Charmander or Squirtle, and I started with Squirtle, so I have a warm place in my heart for Squirtle."

So there you have it, folks. Mark Ruffalo loves Squirtle. Now, with that knowledge, you can get on with your lives.
