I'm specifically wondering about the ones that come with this set (though if all Legends effects use the same type of connection that'd be great to know): It's difficult for me to tell what type of connection these use, and I don't really follow Marvel Legends stuff. Just wondering if these effects would be usable with Siege/Earthrise figures.
The connectors aren't the same. The large pieces are flat on the bottom and can be used as props, but the pieces that fit on the ML weapons don't fit on TF weapons.
