can collasal characters carry smaller figs?

no. but you know darn right that they should be able to!
also, this is a rules question :-)

There's no rule that grants collosals the ability to carry... but every collosal that's been made so far is a flyer. Therefore, they can all carry other figs.

Added a bit to make it more clear.

Can a Collossal fig capture a Giant?

Does anything in the Giant rules say they can't be captured?

























(ans: nope, no special rules. they can be captured the same as just about everything else.)

I thought so. Cheers.
