if it is a real plot point, then i can tell you exactly what the statue is, what his plot relevence will be, and what his powers are.
he is the head of the ootsutsuki clan and final villain of the boruto series, and has no motivations whatsoever, just a general malevolence. his powers are that he has about fifty Sharinnegan on his body, as well as tenseigan and a forehead tenseisharinnebyakugan, and on top of that has more chakra than a hundered juubi's stacked on top of eachother. he has no personality, or even lines, and is forgotten ten seconds after he is killed by boruto and sarada's son, who uses some kind of crazy chidorasengan and becomes the 10th hokage.
or, much more likely, he was a background statue with no plot relevance.
