winning Bonne Mecha design is the Donner Wels by Kobun #46 of the Japanese Devroom (and author of the famed Japanese fansite Cap Kobun).
It was a rather difficult decision, but ultimately the The Donner Wels came out on top. The electricity-based mech will go on to appear in Mega Man Legends 3 as a real boss battle, piloted by none other than Bonne family!
Legends 3 director Eguchi notes the team will "do a bit of revising and “recipe-altering” on our end in the interest of quality and what-have-you. So please bear with us and look forward to seeing how this mech ultimately turns out!" What you see here may not necessarily reflect the final design, in other words.

A big congratulations to #46! And let's not forget to applaud the other designs; excellent work all around, everyone!
