Articguana wasn't really weird, he just wasn't seen since "Arrested Development" so they used him hastily.

Slapstrike and Unitaur would not ever be in Omniverse, but if Ben got a Lenopan in his omnitrix...

Collectimus' voice was just like a stereotypical card-playing nerd, so it was fine for the situation.
