People have done this before with the titan hero tech figures from avengers age of Ultron, where they put one of the figures further, at an extremely far, the Hulk buster figure will respond. But I recommend that the infrared sensor is supposed to be facing towards him, facing forward when going out of further distance. If the sensor it’s not close to him like tilted, or in a different direction that it will not react. I made a few updates. And put in the comments below if you see someone beside the Hulk Buster right on the right side. And when I said about the updates, I mean channel updates.
