Hmmm...
In no particular order...
Tamers Renamon
Tamers MarineAngemon (I can't help it, she's so cute, it's like watching a puppy and a kitten try and fit into the same slipper, except she has destructive bubble attacks)
Tamers Antylamon (A giant rabbit with axe-hands, awesome)
Silphymon (Just looks awesome)
Ranamon (I only saw the dub, and I like a southern belle)
