SY208 Heroes Assemble - Big Blaster Gun sets

SY now like to come out bigger (pricier) box set with previously un-released Mini figures. The minifigs variant are good, my kids love the gun, but they are just a bit too loose to manipulate. One can secure the bricks with glue if wants. Searching from the net, seems like I do not see any Lego with this gun assembly. Is this "ori" SY creation?

Magneto

Dark-tor DOOM (most solid among the four)

Black Bolt

Phoenix - and her water gun (the most fragile - my son says its a giant blow horn)

Good mini figures variant
