Tosanaizer V

Tosanaizer V (トーサナイザーV) is an enemy in Mega Man 11 that appears in Bounce Man's stage, as it was designed to stop people from trying to jump over the pits in Boing-Boing Park. If Mega Man gets too close to a pit where a Tosanaizer V is located, it'll emerge from the pit, linger at the top of the screen for a second, and slowly float downwards. To get past a Tosanaizer V, Mega Man can maneuver past it once it starts to descend or just destroy it (though a new Tosanaizer V will replace it shortly afterwards). If Mega Man collides with a Tosanaizer V, it'll push him back with its big hands.

Trivia

 * Its name is probably derived from the word "tōsanai zo (通さないぞ)", which means "I won't let you pass through".
