Heartwarming / Rocket Power

• The bond between the four kids in general. They may have their disagreements and arguments, but when push comes to shove, they're always there for each other.
• In Escape from Lars Mountain, after being picked on by his brother Lars for one too many times, Twister then comes up with a heinous plan himself and lets Otto, Reggie, and Sam in on it. When Lars and his goons find Otto, Reggie, and Sam, with Twister nowhere in sight, Lars shows sincere concern for his brother since it's getting late and his parents will go ballistic if he comes back home without his brother, to which Otto tells Lars to look for Twister on his own. Lars frantically searches for his brother throughout the night, only to find his shoe near a raging river. One of Lars' goons then makes a gesture suggesting that Twister was Driven to Suicide, much to Lars' horror. Otto, Reggie, and Sam catch up with Lars and his goons, Lars telling Twister's friends that he would never want anything bad to happen to his little brother. Lars then confesses that just because he picks on his little brother so much, it doesn't mean he doesn't care about him, and is close to tears, until Twister reveals that he's still alive and he was hiding nearby.
• In one episode, a new kid and tag-along named Josh Grody tries to join the group, which proves to initially be unsuccessful. It's only by Sam's openness that he gets into the group. Unfortunately, Josh repays him by pushing Sam to the side and actively replacing him. When Otto, Reggie and Twister eventually learn this was Josh's intentions, they don't take it so well. After finding Sam, they let the poor kid know nobody could ever replace him.
• In "The Great Sandcastle Race", they unfortunately find out that it's too close to the ocean and the tide threatens to wash it away. They try several things to hold the water off such as digging a moat for the water to come in and forming a barrier with their skim boards. Twister at one point seeks assistance from Lars and friends, but is laughed off. Just when it looks like the group is going to be overcome by the tide, a hand reaches past to help steady the barrier— Lars's hand. He and his friends add their larger surf boards to the barrier, keeping the water at bay long enough for the judges to note the kids' contest entry.
• Lars yelling at his friends for insulting Twister.
  Lars: Hey! Don't insult Twister! Only I can insult Twister! (smiles warmly at Twister) It's a brother thing.
  Twister: Right. It's a brother thing.
• In "Father's Day Off", Sam's dad comes to visit him, but spends the entire day talking on his business phone and completely ignoring Sam. But once he realizes what he's been doing, he throws the phone in the back seat of the car and takes Sam out to spend time with him.
  • Heck, his second attempt to spend time with his son proper is one big Meaningful Echo to his previous attempt. The first time, he kept answering his phone, brought Sam's friends along (thus defeating the purpose of father-son quality), and only did activities they wanted to do. But the second time, we get to see Sam's father actually take the steps to rectify his mistakes. He lets Sam know it's just him and his father, makes certain to only do something that's more his son's speed, and puts all phone calls on the figurative back-burner. All in all, it's heartwarming to see Sam and his dad exchange appreciative smiles.
• In "Reggie's Choice", Reggie is torn between a volleyball tournament and a street hockey game scheduled at the same time. After seeing her in action on the volleyball court, Otto gets the hockey game rescheduled so Reggie doesn't have to choose between her new team and her old one.
• An unexpected but welcome one comes in "Reggie's Big Beach Break". Merv is his usual disgruntled self throughout, becoming especially angry when a group of college students turn up at his house and use his pool for a seemingly never-ending party (which is understandable). Finally, after many a sleepless night, he marches out and tells the ringleader of the students to leave. Now, in another show, this would be where shit hits the fan, but what does the young man do? He simply tells the others it's time to leave, which they do. Merv feels bad after this, but the college student assures him it's okay and that he understands he's old and needs his peace and quiet, even giving him a hug as thanks for being such a gracious host. Merv's reaction is one of both utter shock and genuine delight, so much so that he decides to actively host the afterparty for at least one more night!
• In "Back Bowl," after Otto and Twister get lost in the titular area of skiing-and-snowboarding area that's off-limits, Reggie and Sam tell Raymundo and Tito about it, and the four of them go to save Otto and Twister. After bringing the boys back to their lodge and the adults lecturing them about never doing something like that again (especially since those areas are off-limits for a reason), Otto (who had previously made Reggie and Sam promise not to tell Tito and Raymundo about where he and Twister were going) seemingly gets mad at them for breaking their promise. Reggie defends herself and Sam by claiming, "Well, it was getting late and we didn't know what else to do!" But Otto simply smiles and says, "Thanks for breaking my promise."
• In "A Rocket Powered Xmas", Otto and Reggie work extra hard to buy Ray the exquisite surfboard he'd been ogling in the shop window. And they actually pull it off. What does Ray reward them with? Gifts that are mementos from their mother. Both are visibly touched and cherish the presents, very clearly missing their mother but glad to have their father by their side.
• In "Race Across New Zealand", Mr. McGill's son, in contrast to his father, is perfectly friendly, has lots of respect for his opponents, even through his snark, and proves to have lots of honor when he refuses to accept a win by cheating.
  • When Twister injures himself during the last leg of the titular race, Otto tells Reggie, who he had been insulting and mistreating the whole movie due to Raymundo's Parental Favoritism, to go on ahead because he's not leaving his best friend alone when he's hurt and is openly proud of Reggie's win.
  • When Mr. McGill is exposed as a cheater, he is immediately stripped of the title he'd won years ago, and has given to Raymundo. Looks like the latter's biggest failure of his life is finally behind him now.
• A general one for Otto. Yes he will pick on his friends and butt heads with his sister more than might be healthy but if anyone else does it, there will be hell to pay.
• Another general one for Otto. Whenever Reggie gets a new friend, or hangs out or does something outside the group, he gets all sort of bent out of shape, and jealous. He almost feels like he is losing his sister. It goes to show how much he really loves Reggie and how he considers her not just his sister, but also his best friend and life partner.
• Violet's Flower is a role reversal that seems almost completely out of character for both Merv and Violet. The gang accidentally destroys Violet's flowers, pushing her into a borderline Angst Coma for almost the entire episode. Merv is annoyed, but he's actually quite understanding to the kids - he knows it was a total accident, and that they feel bad for it. His annoyance isn't at the children, it's at the fact that there's no way to actually fix this situation. But when the children suggest winning the roller derby for Violet's sake, he's very willing to listen.
• "Netherworld Night":
  • It's Otto, of all people, who accepts Eddie's invitation for a sleepover at his house. Everyone else in the group was too creeped out by the idea of being in the "Prince of the Netherworld"'s house, but Otto says he's their friend. Even when later thinking the house does look too creepy to enter, Otto suggests a campout in the backyard rather than hurt Eddie's feelings by refusing to come over.
  • After Lars and his crew try to take advantage of the situation for a prank, the group and Eddie return the favor with the help of Eddie's parents. It's through this we see that Eddie's mother fully supports his quirky behavior and that Eddie's Prince of the Netherworld schtick was inspired by his father's own theatrics.
