This article focuses on the interactions between Splendid and every other main character he has interacted with.
Splendid appears to be a role model towards the other characters as he is a famous, albeit bumbling, superhero. Most characters have similar thoughts towards him, exceptions being Pop and The Mole. From Splendid's perspective he usually tends to be alone and doesn't really interact with other characters as friends since he other leaves after he saves them.
Cuddles seems to be a fan of Splendid. He appeared in Wrath of Con to listen to his speech, along with various other characters. Splendid also tried to save Cuddles in From Hero to Eternity (though he killed him accidentally as usual.) In Just Be Clause, Splendid accidentally slices Cuddles in half with his heat vision, so Cuddles gives Splendid his basket of eggs that need delivering. Splendid agrees to do so, but he rips off Cuddles' ears before leaving.
- Main article: Splendid-Giggles Relationship
Like most characters, Giggles is a fan of Splendid despite his inability to do his job right. In most of their appearances together, Giggles is usually the damsel in distress with Splendid having to save her (and accidentally kill her seconds after).
- Main article: Splendid-Toothy Relationship
Toothy appears to be a big fan of Splendid, from dressing up like the superhero in Remains to be Seen to attending his speech in Wrath of Con. The only exception would be in See What Develops, where Toothy gets mad at Splendid for mistakenly beating up Giggles.
Lumpy seems to like Splendid, though they do not interact often. In It's a Snap, Splendid rescues Lumpy. In See What Develops, Splendid is employed by Lumpy. In Breaking Wind, he saves Lumpy again but cares more about his book. In Just Be Clause, Splendid accidentally kills Lumpy, who is Santa. Lumpy entrusts Splendid to deliver the rest of the presents, before he dies. Splendid accepts the task, but tears off Lumpy's beard before leaving.
Splendid has tried to rescue Petunia on several occasions, all with unsuccessful results. She may be a fan of his, as Wrath of Con may suggest. In that episode, she and Giggles were pleased when Splendid recharges Giggles' light saber. However, she didn't seem to want to attend his speech. In Just Be Clause, they interact again when Splendid bursts into her house as Santa. Splendid gives her a ring with a piece of coal and crushes it to make a diamond. He also crushed and broke Petunia's fingers but she doesn't seem to mind as she is happy with her present.
Handy can be considered a fan of Splendid, as he appears in Wrath of Con and listens to Splendid's speech. However, Splendid accidentally kills him (and many other characters) in Gems the Breaks and in Breaking Wind.
Much like everyone else, Nutty is a fan of Splendid. In Wrath of Con, Nutty went to attend Splendid's speech and he was the only one who was not suffering or showing pain from Splendid's bumbling.
Sniffles is shown to be a big fan of Splendid. Aside from owning Splendid-based merchandise, as shown in Suck It Up and A Sight for Sore Eyes, he also wants an autograph from the hero in Wrath of Con. Splendid happily proceeds to do so, only to accidentally kill him and then run off.
In From Hero to Eternity, Pop is clearly annoyed after Splendid nearly blows away his newspaper twice. However, he didn't seem to mind Splendid interviewing him in See What Develops; though he most likely didn't recognize him in his disguise. He even takes Cub to a Splendid convention, despite not being fond of Splendid himself.
Flaky may be a fan of Splendid, as she was seen attending his speech in Wrath of Con.
- Main article: The Mole-Splendid Relationship
Splendid is obviously not fond of The Mole. He kills him with no remorse whatsoever in Gems the Breaks, and is obviously annoyed that he is paired with him in See What Develops, going to great lengths to stop him when The Mole accidentally takes a photo of him transforming.
Disco Bear is a fan of Splendid in Wrath of Con, and was one of the few characters in line waiting to get an autograph from him.
Russell is shown to be a fan of Splendid in Wrath of Con.
Cro-Marmot's only interaction with Splendid occurs in See What Develops where Splendid is annoyed that Cro-Marmot is in a different phone-booth.
