I personally loved his Bowser in Super Mario.

One I did was “joke character who ended up being very serious.”

Wait a minute, that set glows in the dark?! I’ve had a set that looks like that for years, and had no idea it glowed!

Wait, they don’t use magic items!? What the actual fuck? Of course it’ll be hard if half the party literally can’t hurt it!

Nice! I had a 3.5 campaign I was running once where one of the major plot points was going to be a guy who was cloning Tarrasques and experimenting on them, but the game fizzled out because of me falling down on the job.
