The female characters' names are on the left & the males' are on the right of the image.
...So, here's her full name: Tinker Rhonda Bell.
Coincidentally, Brain & Brian are anagrams (different words with the exact same letters); however, the name of this character below is Brain. If you spelled Brian instead of Brain, then I won't count it as an incorrect answer since I'm a nice guy! Besides, this puzzle is quite tough! But factually, his name is Brain.
