Yes, that video has pretty strange selection of tanks, including fictional.

And it misses real tanks designed and made by Edward Grotte, German who worked in USSR in 30s (and then worked in Germany again), like TG (Tank Grotte) and TG-5. First one was very real and made in metal, it was pretty modern medium tank, second one was crazy project of 1000 ton tank that, of course, wasn't made.

There also were projects for 200-400 ton tanks, live VL (Vladimir Lenin).

Idea of super-heavy tank was interesting in 20s (literally mobile fortress), it died in 30s but ressurected for small amount of time after Finnish war, where problem of defense breakthrough was pretty serious.
