This is not a gif (obviously) because the image literally appears for one frame in the opening credits of the Mortos Der Soulstealer episode.  I haven’t colored or enhanced the image in anyway, so this is exactly how it appears in the show.  Bloody GIR appears in other episodes, but this is the clearest still of him that I can find.

How can you still make Invader Zim gifs for a long time? It's so great that you never left... Thank you! Invader Zim may bring back horrible, awkward, weird, memories, but hey, there will always be a place for that weirdo in our hearts! Thanks again for not giving up on that little mutant thing. :)

I don’t know, man. I just enjoy making gifs, I guess. I like running this blog and I wish I had more time to dedicate to it. Also, I have nothing but good, fun memories of the show.  I started watching it when I was just a wee lass of 8 and it’s been a part of my life ever since.  I like the show too much to just stop. So…yeah…
