Strangely, going by the story included with the Beast Hunters products, it seems like the final battle is supposed to be with Prime fighting Predaking, not Megatron. However, after watching the series finale, this is far from the case. Predaking hardly did anything in the final battle.
In the series, Predaking’s mass must shift or something. In robot mode, he’s slightly taller than Megatron. But in Beast mode, he’s huge! So the Ultimate Class version’s beast mode is actually better suited for the Legions figures. Weird.
Predaking stands a little over 9” tall.
Comparison with the Voyager version.
