At 30 cm this is one of the larger Marvel figures Hasbro makes: Hulk in green with purple trousers, solid enough to grab with both hands and big enough to stand out in the toy basket.
Arms, legs and head move along, so you can set him down in whatever pose the story calls for: mid-swing, shielding the rest of the team, or simply upright on a shelf. There is no electronics inside, so you need no batteries.
His back carries the connection point of the Titan Hero Blast Gear range. A launcher or Power FX pack from that same range clicks on there. Those accessories are sold separately and are not in the box; you get the figure.
Its size makes it a gift that lands the moment it is unwrapped, with nothing to assemble or set up first.
