Cool. What scale would there Preds be?
A little bigger than 1/12, can sometimes scale with Marvel Legends, so a Predator would be like 7.5 or 8".
For reference:
-Figuarts/Figma: true 1/12, so they're tiny, they're not gonna be 6" unless the character is really 6 feet tall.
-Mafex: a little bigger than figma.
-Mezco/Legends: Super blown up 1/12, they're almost not in that scale anymore.
At the end of the day they're all within the same scale and can scale with each other with posing and perspective.
Edit: Neca/StormCollectibles would be 1/10, entirely different scale, and it's much more noticeable.
