Avengers Infinity War Hulk Figure Articulated Game and Action Figure Titan Hero Series

I bought thanos he didnt come with fx pack to make him talk .iv looked every where to yry and buy it but ben unable to .where can i buy it seperetly

i bought iron man and hulk neither came with power packs. ive searched everywhere for just the power pack and cant find it by its self please help?

Does the genuine hulk seem hollow and can he do splits (like spiderman and ironman)? trying to distinguish between real and knockoff.

Can anyone provide a link to where the power pack can be bought?
