I always pick the fire starter, and I liked Incineroar, but he's got two glaring flaws:
the comically oversized baseball mitts for hands. I was hoping it just looked like shit in the official art but the hands looked bad in-game too.
I can understand him having big hands as a design choice, but they didn't need to draw the sausage fingers if they wanted him to have big hands. Overall, 8/10 fire starter (worse than Charizard, Typhlosion and Emboar, better than Blaziken, equal to Infernape and Delphox)
