But with all that being said, Mountain does stand at over 7'8 feet Tall, and weighs around 2000 lbs. He is also know throughtout the Star Verse Universe as being the single strongest superhero that there is!

His main enemy is Dr. Clock. They have battled a number of times, but as far as I know, every battle has either been stopped or interfered in.
