This is 'Russian X-Men', a video somebody stitched together from various Youtube clips to make a
low no budget opener for a live action Russian X-Men show. Now I'm not saying this video is the exact reason the internet was invented, but I did just text Al Gore and he didn't deny it.
Keep going for the WTF-Men in action.
Thanks to zootghost, who agrees now that's a superhero team you can trust.
