When I ran Rime of the Frostmaiden I had a player who made a lizardfolk wizard. Lizard Wizard. The game was online so here's his VTT token.
In session 0, most of my players were getting used to roll20, so I ran a big combat to start the campaign off - ambush by ten goblins and two dire wolves.
On the wizard's first turn, he's like "I got this" leaps from the sled, sprints across the battlefield to a goblin archer, and bites the guy in two.
Wizard.
Good reveal for an NPC. Wizard runs out of spell slots in a dire need. Actually also has 10 levels into Monk but never mentioned it.

Because you can't cast spells while raging, so a barbarian/caster multi-class is usually a bad idea.
Just because something is a bad idea, doesn't mean it doesn't work for a person at the table. It's just suboptimal, but that doesn't mean "bad" unless you are playing with powergamers who will flame you
