Black Yoshi

Role
Black Yoshi is one of my personal favorite characters. He was almost definately the strongest fighter in the battles, being good on planes and on foot. He started his career off in "Team 0" as well as many other characters, and was the best on the team, claimed by Mario himself. Although he was a lovable and heroic character it didn't turn out well for him in the final battle. His bravery took a turn for the worst and he passed away after a plane crash.

Death
Died in Season 1 - Episode 10 - "The Finale"

His death was the most impactful of the series. Seeing such a brave and strong character fall in his cousins arms was almost heartbreakin. In a plane fight he was shot out and crash landed in the Canyons where he suffered until the rest of "Team 0" found him. Unfortunately it was too late for them and Black Yoshi was seconds away from death. His famous last words to Blue Yoshi were "Finish this," and thats what they did in his honor.
