Missile Banzai Bills are enemies in New Super Mario Bros. Wii. They are a sub-species of Banzai Bills who attack by homing in on players while flashing from black to red constantly. Missile Banzai Bills only appear in World 9-3, along with Missile Bills. They appear in the very last part of the level, which features many yellow platforms moving either side to side or up and down above an ENORMOUS gap. Here, they are shot out of nowhere while Mario and the crew (Luigi, Blue Toad, and Yellow Toad) cross platforms. They then appear and move themselves into Mario and the crew's position before trying to ram into them. However, if the Missile Banzai Bill happens to miss its target (say you avoided it by jumping over it), the Missile Banzai Bill will not turn around and instead keep going straight, unlike Missile Bills. Missile Banzai Bills can simply be defeated by jumping on them, much like with regular Banzai Bills, or by ramming into them while under the effects of Starman (this may be either impossible or difficult to perform since the Missile Banzai Bill part is the last part of the level and there are no checkpoints in this level). They can also be frozen using the Ice Flower's/Penguin Suit's powers, however, like most other flying enemies, these enemies will bust right out after the iceball touches them. Also, POW Blocks are useless against these enemies.
