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 often leaves after he saves them.
Splendid tried to save Cuddles in From Hero to Eternity (though he killed him accidentally as usual.) In Just Be Claus, 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.

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.
In Wrath of Con, he helps her and Giggles when the latter's lightsaber stops working. In Just Be Claus, they interact again when Splendid bursts into her house as Santa.
