Alan, Kirk, Abel and Rodney.

Also: Hawkbreast, Bisonbreast, Eaglebreast, Jaguarbreast, Lionbreast, Rhinobreast, Tigerbreast and Koumoribreast (Koumori means "bat" in Japanese - so it's basically "Batbreast"). Then there's Death Cobra's unnamed partner, whose name was probably something unimaginative like Cobrabreast. Or maybe it was something different like Serpentboobs.

Kup is also a weird name. WTF is a "kup"?! (o_O)

Then there's moments of Fail English, like Beast Wars' Lazorbeak (someone forgot how to spell laser) and Wind Sheer (should be spelt "Wind Shear")
