OOO crest combinations

Does the Sasori Kani Ebi medals
...........(Scorpion Crab Srimp?)
And the Same, Kujira Ookamiuo
...........(Shark Whale Wolffish)

Have a chest all together? Like the Tatoba chest?

I think this should work out for you.

I agree with Brainchild. alpha-vector does good work on OOO's O Lung designs. I don't think you'll be disappointed.

Thanks.
Now I'm just looking for the Crab, Shrimp, and Scorpion Chest
any ideas?

They don't have an official one, since they were used for Kamen Rider Core. There are a bunch of fanmade ones though

Point met to some? Ill take a look.
