Heartwarming / Ultimate Muscle

• Kuroe/Lord Flash revealing that he's Warsman and telling Kevin that he gave up his original nationality to dedicate himself to helping out the Robin Clan in their time of need. True loyalty comes before one's nationality, after all.
• After defeating Mantaro at the finals, Kevin Mask and Mantaro congratulate and praise each other for the war in a display of good sportmanship. May not seem much at first, until Kevin's post-fight monologue before that moment, he was planning to slap Mantaro with the belt. It really highlights both how much Character Development Kevin got, and how he grew to respect Mantaro.
• Hanzo is fighting Gepparland for one of Meat's body pieces, and getting trashed. Hanzo then is approached by The Ninja's spirit. Bear in mind that he was killed by Hanzo and Hanzo murdered his student before that. Hanzo thinks he's here to laugh at this suffering. Ninja's response?
  The Ninja: Laugh? Why would I laugh... at the suffering of a fellow hero?
  Hanzo: Fellow... hero...? But... I killed you and your student with those hands...
  The Ninja: I no longer harbor any ill will towards you. No matter how wicked you once were... you're now giving your last breath, your last drop of blood to save humanity. We're friends, Hanzo!
• Ashuraman and Sunshine reuniting with eachother and leaving the Demon Womb together after Mantaro defeats Ashuraman. It goes to show that even in their old age, they still care deeply for one another.
  Ashuraman: S-Sunshine!
  Sunshine: There is friendship even among devils.
  Ashuraman: "Friendship among devils." I've heard that before.
• From the Ultimate Muscle: Legends vs. New Generation game, we have Robin Mask's story. After fighting through the New Generation members to get to fight with Kevin, Kevin reveals his hatred for his father due to his spartan methods. Robin agrees to fight Kevin if it means thawing the ice in his heart. Robin then, in his own way, apologizes to Kevin for how he treated him, acknowledged that not everyone that can take harsh methods like he could, and passes down the Anoalo Staff to Kevin. They then finally make amends.
• Despite sharing the same respect for Mantaro than the rest of the McMadd family (i.e. nothing at all), when Jacqueline McMadd witnesses Robin Mask's brutal trashing of Mantaro, she actually cries and starts praying for Mantaro's safety, treating her former callous disregard of Mantaro and the whole Choujin Olimpics as her personal My God, What Have I Done? moment.
• In the climax of the Poison Six-Pack arc in the anime, Mantaro is on the threshold of life and death; as he floats along the Sanzu river? The spirits of Minch and The Ninja encourage him to come back by showing him how much he is being cheered on, not just by his closest ally's, but the world over.
