Fat Buu is the most recognizable, so it's not too big a surprise.

I bought Funko Pop! figure of Gigantor (Tetsujin 28-go). Gigantor was the first mecha anime that I saw as a kid long before Gundam Wing was release in the US and I'm a retro anime & manga fan myself. So I had to pick it up. Very nice figure in my opinion. I'm surprise to see Funko do a figure on such a obscure character seeing that most casual anime and manga fans don't know what Gigantor is.

Here's a question for you guys, Do you keep the Pops! in box or take them out?

Took it out. Then again I'll only ever own one.

So what Funk Pop figures you would like to see be made? Pop figures I would like to see made:

Aqua Teen Hunger Force
Castlevania
Evangelion
Digimon
Left 4 Dead
JoJo's Bizarre Adventure (Seems possible given how popular the series has become lately in the west)
Mortal Kombat
One Punch Man (Also seems possible given how popular the show is)
Ratchet & Clank
Robotech
Street Sharks
Tiny Toons
Yu Yu Hakusho

I'd become a lot more active in buying these if they did Digimon.
Tamers.
Specifically Tamers. I ain't looking for Agumon, Wargreymon, or Angemon.
Guilmon. Takato. Dukemon. Rika. Renamon. Terriermon. Henry/Lee.
Them.
Not Adventure, not 02, and certainly not Tri.

Gundam Pop figures would be cool. I would imagine Funko would mostly do G Gundam, Wing and Iron-Blooded Orphans since those air on Toonami and probably more well known to most casual anime fans.
