Fantastic Four Suzan shrinking micro (HD reupload)
Expanded and in Full HD! One of Reed's microverse experiments causes the Fantastic Four to shrink constantly. H.E.R.B.I.E. mistakes them for mice and rats and tries to eliminate them. Ant-Man comes to the rescue.
Thanks to @nekomimigenie for the heads up!
From "Fantastic Four", episode "World's Tiniest Heroes"
