My secondary protagonist is a 12-year-old boy with super intelligence who creates a suit which grants him invisibility and has powerful electromagnets in the boots and gauntlets. As a result, I had given him the in-story nickname of "Tesla Kid", but I'm starting to think this sounds silly. Would "Teslageist" sound better? I prefer this as it incorporates the key features of his suit without making him sound like a child. Which name do you think sounds better?
Telsa sounds feminine, like "Elsa". It would for a gender swap version of the character from an alternate universe story line I've got planned.
The main character often calls him Tesla, but with his OCD he gets annoyed at his name being shortened, at least at first. Maybe I could go with Tesla and she calls him "Tes" for short for the same purpose. You've given me something to think about.
LOL. First of all, I like your ideas. Secondly, I'd recommend you to use Tesla Kid as a nickname, but as for his real name, you should choose [IMO] something like Artemis Fowl.
Thanks, Veo, you've got a pretty good set-up for a story yourself. I've already picked his real name - Boris Petrov. Though I like the sound of Artemis - it sounds like a strong name. It could work quite well on a character I have planned for a later book in the series. Boris is more of an inventor in this instance, though the original meaning of his name means "One who fights for justice".
I should have left the poll open a bit longer. Looks like Tesla and Teslageist are currently tied. Though he was originally called "Captain Magnetic" in the first draft.
Remember that Petrov is a Russian surname. If your character's ethnicity corresponds, then you're okay.
