If you are interested in making your own MMD videos, HBR102989 has made his Krystal rig available. It contains both the Star Fox Assault jumpsuit and the Star Fox Adventures outfit. Download it here! There are other examples as well.
I'm fairly certain that HBR102989 has posted some videos of his own MMD rig on his channel, featuring simple animation and lip syncing. Two of them are included here.
