Here's his trait:

ALL THE POWERS OF THE LEGION: Once per game, choose up to 4 characters with the Legion of Super Heroes keyword and different names from your sideline and roll a d6 that can't be rerolled. Turn their dial numbers to the click number matching the result. At the beginning of your turn, choose one character on your sideline that wasn't chosen last turn; Composite Superman can use the powers and combat abilities of the chosen character until your next turn. Give Composite Superman a power action and you may roll a d6 and turn the 4 characters' dials to the click number matching the result.

Tell me if I'm right:

Combat abilities are the symbols next to your stats, and the "Improved" X, and grenades.

Team abilities are not Combat abilities.

Right?

If you look on the other side of the PAC, you will see all combat abilities.

Team abilities are not among them.

EDIT: And just to correct you on one thing. The symbols are not combat abilities. Certain symbols grant the character possession of certain combat abilities.

Thank you for asking this! I seriously didn't realize that the Improved ___ would apply, as would Duo powers... and Giant/Colossal abilities? Never even thought about that with him. Rep to you!

If CS chooses SLoSH001 Cosmic Boy, he would not gain the symbol, but he would gain use of the indomitable ability because that is a combat ability that Cosmic Boy has.

He would still keep the regular old , though.

So Improved movement or targeting applies if Comp Supes is using a sideline character with that on their dial? I did not realize that. Makes a difference for how I choose now.

That's what I'm saying! LOL! His line, "Composite Superman can use the powers and combat abilities of the chosen character until your next turn" is something I glossed over and didn't connect that he could gain Flight, Indom, Giant Size (Colossal Boy), Duo (Tornado Twins), and IT/IM as those are all combat abilities!

CS can't use traits (and we've already discussed TAs) as one major limitation... if he could, that would be NUTS!
On the plus side of him not being able to use TAs, that also means that having Mon-El (Superman and/or GL TAs) on the sideline wouldn't prevent you from using Legion Lost.
