Tommy was an amazing character is Season 1 & 2 when he was the green ranger, with the exception of "King for a Day" & "Fighting Spirit" I never felt the character was anything special or memorable after he lost the Green powers, so this is why I do not include him.

Plus

My choices in no particular order:

Jack Landors: SPD B-Squad Red Ranger - Power Rangers: SPD
Tori Hanson: Blue Wind Ranger - Power Rangers: Ninja Storm
Anubus "Doggie" Cruger: Shadow Ranger - Power Rangers: SPD
Jason Lee Scott: Red Ranger/Gold Ranger - Mighty Morphin Power Rangers/Power Rangers: Zeo
Carter Grayson: Red Ranger - Power Rangers: Lightspeed Rescue


I also thought Vida was awesome! Good choice! And I feel exactly the same about Tommy. I think he was a good character a bit overrated. There are plenty of other characters that deserve a chance to shine.
