Dodonpa Cannon (ドドンパ砲,Dodonpa Hō?) is the cannon enemy in Mega Man 8 and Mega Man & Bass. It can turn and change its angle to shoot bombs that go in an arc.
Aloha Dodonpa (アロハドドンパ,Aroha Dodonpa?) is a variation of the Dodonpa Cannon that appears under artificial palm trees from the first stage of Mega Man 8. It emerges from camouflage when Mega Man comes in range of its cannon blasts.
