Here's Luigi's signature movement in Super Mario Bros Heroes of the Stars.
You saw his move in SMB Heroes of the Stars Episode 2 Part 2 when he fight Bowser JR and defeat him.
Well, as you know Luigi can use thunder element in Mario & Luigi Superstar Saga, so I added Luigi use Thunder Element. That's all.
Hope you like it.
