Certain characters in Super Smash Bros. Ultimate take damage while being submerged in water. Being Fire-type Pokémon, Charizard and Incineroar are among this group. Inklings and Sonic also fall in this category, as shown in the embedded video below. You’ll notice that Charizard takes it a step further by trying its best to keep the flame on its tail from getting wet. Super Smash Bros. Ultimate is available now on Nintendo Switch.
