Midoriya
Go beyond! Plus ultra!
My least favorite character is always changing, but pretty much any character with abusable projectiles. People just don't know how to limit themselves. I hardy see any Links use their sword anymore. It's like bomb, arrow, boomerang, and repeat. Not saying there are players who can't use them. I just tend to run into the spammy ones the most.
LOL it's funny how Link is most known for his sword throughout his games, yet nobody uses it in Sm4sh anymore... XD...
