- Macku and Hewkii on the lily pad.
- The ending of the Bohrok animations, after Macku, with a flower decoration on her mask and necklace, drags Hewkii for swimming lessons, Hahli then comes over to Jaller and Takua with the same flower decoration and necklace, puts her flower onto Jaller's mask and leaves. Jaller then decided to stay at Ga-Koro longer to spend time with her.
- After Tahu is cured of the Rahkshi's poison, he and Gali have this exchange -
Gali: Brother... are you well?*Toa fist-bump*
- Keep in mind that they've spent the rest of the movie and half of the events before it bickering with one another.
- Turaga Lhikan's Heroic Sacrifice, and his last words to Vakama in Legends of Metru Nui. It's especially powerful when one remembers that Vakama had spent most of the movie doubting his ability to be a leader, questioning his visions, and blaming himself for Lhikan's capture.
Vakama: That was meant for me.Turaga Lhikan: No. This is my lifetime's journey. Yours lies beyond. Trust your visions. I am proud to have called you "brother"...Toa Vakama.
- The scene at the end of Bionicle 2: Legends of Metru Nui where Vakama gives Turaga Lhikan's mask to Jaller, whose Matoran mask is broken, and then it molds to fit his face, is incredibly Heartwarming.
- This makes Jaller's Heroic Sacrifice in The Movie when Takua is under attack by Rahkshi Turahk even more heartwarming, because it means that some of Lhikan's spirit lives on in him, and so means that the already heartwarming moment when the Takanuva-Makuta hybrid being resurrections him from just the mask is just that much sweeter.
- That scene at the end is heartwarming and for another reason. It chronologically takes place after the events of Web of Shadows where the Toa have lost their powers and begin to doubt themselves. They spend the rest of the movie trying to recover their powers aside from Vakama who doesn't take it well. After they recover their powers and save the Matoran, bringing them to the island of Mata Nui, they realize that they must now give up their powers which they worked so hard to recover but Vakama does so without any hesitation and the others follow immediately.
- In "Web of Shadows", when Matau tried to reason with Vakama, how does he eventually snap him out of his Brainwashed and Crazy state? By jumping off a cliff knowing his brother would save him!
Vakama: (Matau manages to grab onto the edge to avoid plummeting to his doom.) You are weak, brother.Matau: You're right, Vakama. I am weak... We all make mistakes, Vakama. That's what happens when you're brave enough to make decisions. I understand that now... (Vakama steps on his hand, trying to get force him to fall) Wait! I'm sorry. For doubting you. Our strength comes from our unity, Vakama. Which means... you can't be strong without us.Vakama: (interjects) I'm better, stronger alone!Matau: I don't believe that! And I don't think you do, either. You're our leader, Vakama. You're my leader. We've got a job to do! ...And if there is any of the Vakama I know left, he'll know what to do...
- The ending of Bionicle 3. Norik tells Vakama that the Matoran are now his responsiblity. Instead of reacting with crippling self doubt as he would have in Bionicle 2, he simply reacts with a "well how 'bout that?" smile to himself, neatly accenting the Character Development he's been through.
- This moment from Time Trap:
Nokama: You sound so confidentVakama: Why wouldn't I? I'm with you.
- Matoro willingly gives his life to revive Mata Nui, and with his last bit of individual thought before transforming into pure life energy, teleports his endangered teammates back to Metru Nui and grants them the ability to breathe air again. This selfless act later causes the Ignika to commit a Heroic Sacrifice of its own because the mask was so moved by what Matoro did.
- Kiina after Mata Nui rebuilds Spherus Magna:
Kiina: He said he would bring me to a new world. Instead, he brought the new world to me.
- What's one of the first things the newly revived, and thoroughly confused Mata Nui do when he realizes he's on a new planet? He makes friends with one of the local beetle populations.
- The ending of the Mata-Nui online game is one with the music being something that truly warms the heart.
