Effect: A trio of Velociraptor come and save you from danger by hitting your opponent for more damage when your stamina is very low! In the anime, the Velociraptor turn into energy streams and latch onto the opponent, pulling them up into the air before slamming them into he ground.
Both the Critical Block and Final Fury arcade cards each have artworks that display the Velociraptor attacking the opponent and standing beside the dinosaur using the Move. The only way to distinguish the two Moves is by comparing the Japanese names: Final Fury has 4 characters in its name; Critical Block has 5 characters in its name, the last of which looks like a backwards capital "J" with a double-quote mark in the top-right gap (this: じ).
In the anime, Critical Block and Final Fury are part of the same triangular "Multiple Move" Card created by Seth.
There are 2 versions of the Final Fury TCG card (from DKCG and DKDS) that have different artworks, but are otherwise the same. Of the two, only the second features Velociraptor.
Interestingly, in the arcade, though hopping on the opponent is here shown to decrease their health significantly, the same animation is used for Critical Block, which deals no damage.
