Super Smash Brothers Ultimate - When Byleth got in Smash.

"Another Fire Emblem rep", said the whiner after the 10th mario or Mario-related character is added.

"Wasted slot", said the whiner after the 7th time Sakurai explained that this is not how it works.

"No more swordies", said the whiner as the game gets its 40th fist fighter to fight against the 15 swordfighters, thinking that Meta Knight and Cloud are somehow comparable.

"Nobody cares about Fire Emblem", said the whiner as Three Houses becomes one of the best-selling and best-reviewed games on Switch's history.

"Eww anime", said the whiner about the Japanese game with Japanese characters from Japanese franchises by Japanese developers lead by a Japanese director.

Considering a huge feature in 3 Houses is how you can make your units wield ANYTHING, the best route for Byleth would be to be able to either switch between weapons or just use different ones with different inputs (ie standard and maybe side tilt attacks with the Sword of Creator, but Smash Attacks using Gauntlets, Axes and what have you).
