This is Brocken, one of the occasional “horse suit” monsters they’d throw out. I always like those, although imagining the amount of coordination it took to get them to work right is taxing. Those naughty tentacles got what was coming to them when Ultraman Ace sliced them off. Along with his arms. And head. I mean, you have a move called the Ultra Guillotine, every problem looks like a bared neck.
