Marly Spears (Alternate Dimension)

Marly Spears is the second dimension counterpart of Marly Spears-Fletcher from Phineas and Ferb: Back to the 2nd Dimension.

History
Like Marly Fletcher, Marly Spears' parents died when he was very, very young. However, unlike Marly Fletcher, Marly Spears wasn't sent to the adoption center. He instead was hidden by Doofenshmirtz's minions and later found by a young Isabella Garcia-Shapiro. He was taken to the Resistance to be trained. He became a very helpful member and was a member of Louise Annabelle Crossby's team.

Personality
Marly Spears is very grumpy, unlike his counterpart, which is similar to how Louise-1 is grumpy but Louise-2 is kind. He doesn't understand the point of family, until Marly Fletcher explains. He later becomes kinder.
