Unfortunatly, he was known as the weakest of his siblings (probably weaker than his younger brother Bowser Jr.) due to him being faced in battle before the others in most games. Additionally, he didn't possess a lot of stamina, as he was quite far behind his family, trying to catch his breath, while his siblings were trying to help Bowser up off the ground. Although, this may be due to the fact that he was residing in Grass Land, presumably the furthest world from Bowser's Castle. He, along his siblings will be fighting Mario and his friends in Episode 9.
