- “'Hitmen don't wear mittens! '”
- ―Spike to Whitey
Despite his comical quirks, Spike has a strong desire to be treated like a vicious hitman, however this is undercut by his well-meaning partner and general incompetence. Whilst in some instances he has shown to be genuinely sadistic, Spike over-exaggerates his supposedly villainous nature with evil laughs and puns. Though he fears his boss, The Toad, Spike also wants to boost the Toad's opinion of him and even shows a desire to be friends with him as shown during his excitement when he thought The Toad wanted to watch football with Whitey and himself.
Spike's constant twitching and homicidal tendencies imply that he has gone insane during his time trapped in the sewer.
- Some fans think that Spike reformed, but he didn't reform since he mentioned that he likes unhappy endings with violence just before getting hit by a bottle, hinting that he stayed as a villain.
- Although Spike's middle name is Lesley, he thinks Danger is his middle name.
