Only list characters who debuted in Ultimate Muscle
. For all "legend" characters, add entries at the character sheet for the original series
- Betty and Veronica: Rinko (Roxanne) and Jacqueline.
- Book Dumb: Getting scores in the low-to-mid 20's (still a failing grade) was an improvement.
- Contrasting Sequel Main Character: In comparison with his father, Suguru who was more Idiot Hero and a braggart, Mantaro was an even worse coward than he was, but however, he is more battle savvy
- Crouching Moron, Hidden Badass
- Defeating the Undefeatable: Beat Kinnikuman in a match to graduate from the Hercules Factory.
- He and Chaos beat Kinnikuman and Terryman in the Ultimate Choujin Tag Tournament.
- Kevin Mask in the anime. Prior to that, Kevin only lost once because his Big Bang Edge didn't land on the ring in time for the countdown to be stopped. (He was fighting his opponent outside of the ring)
- Determinator: Having the Burning Inner Strength pretty much guarantees this trope.
- Facial Markings: Like his father, he has the kanji 肉 (niku) on his forehead, but it only appears when he's using his Burning Inner Strength.

- Momma's Boy: Violently so. He first achieved Burning Inner Strength when his mother's cooking was dishonored.
- Punny Name: Suguru came up with the name due to Ultraman (whom he is a fan of) having a brother named Ultraman Taro. He then took the name Kinnikuman Tarou and made it Kinniku Mantarou.
- Trademark Favorite Food: Cow and Rice.
- Aerith and Bob: His parents are named Robert and Suzy and his sister is named Dorothy. Wally suddenly seems a lot more fitting.
- Ax-Crazy: Made this by Neptuneman's Training from Hell.
- Face–Heel Turn: In the Ultimate Choujin Tag Arc thanks to Neptuneman's training to make him a Perfect Choujin.
- Heel Realization: Thankfully as he saw his parents in the past timeline in the audience and decides to fight as a Seigi Choujin but unfortunately later on, Neptuneman and Mammothman immediately ripped his face off after his loss to Warsman.

- You Have Failed Me: Courtesy of Neptuneman and Mammothman in the Ultimate Choujin Tag Arc.
- Improbable Weapon User: This guy makes traffic a viable power.
- Knight Templar
- Master of Illusion: Not to the extent of other Chojin with illusory abilities in the series as a whole, but Dead Signal's deserves mention for manipulating the surrounding environment to create the illusion of the foe being hit with cars, trains and other kinds of vehicles.
- Use Your Head: Your head being a rotatable Yield sign means you have a saw for a head.
- Balloon Belly: Has the ability to absorb his opponents into his body to drown or crush them with his rib cage, bloating himself up in the process.
- Good Is Not Nice: One of the Choujin intended to replace the current Muscle League; Hydrozoa treats his fights with Wally and Mantarou as if he were fighting any legitimately evil foe. Not to mention he seems creepily excited when he decide to absorb Mantarou.

- Cultured Badass
- Heel–Face Turn: Started out as a villain, but turned to the light side after his defeat.
- Feels No Pain: At first. He overestimates this and forgets that he only doesn't feel pain, but his body still feels the damage and strain from the attacks like any other person, and this comes back to bite him HARD against Mantaro, and is the ultimate reason for his defeat.
- Lack of Empathy: His inability to feel pain drove him to label those who do as "weak."
- One-Winged Angel: Grand Slam
- Training from Hell: Sunshine put him through the most agonising regiment ever, resulting in Check Mate finally blocking out all feelings of pain.

- Voluntary Shapeshifting: He can change into any kind of plane to attack his enemies
Barrierfreeman: Nils (Young Body) & Jijioman (Georgioman in US) (Old Body)

He said while Thunder has his own mother to worry about, Lightning says he has no one that will miss him. So, he jumps into the volcanic Mt. Fuji and perishes into ashes.

- How Much More Can He Take?: A lot of Choujin fits this trope, but Thunder stood out. He was thrown into the swords but got back up normally, took a Cross Bomber and lived, accidentally fell victim of his and Lightning's own Death Watch Branding intended for Mantaro and Kevin, then took a NIKU->LAP to finally bring him down, and then somehow... he managed to get back up to stop Mantaro's Muscle Spark from finishing off Lightning!

Other Ultimate Choujin Tag Arc Characters
The Wailing Ghost Gang
