Sari Sumdac is a fictional character in the Transformers Animated cartoon series.

The 8-year old adopted daughter of Dr. Isaac Sumdac, Sari lived a sheltered life until she befriends the Autobot after they saved her upon their reawakening.

She is the primary source of information regarding Earth and its cultures and customs. The security key card she carries is a key shaped shard of the allspark and becomes a curative spark key after her encounter with the AllSpark, allowing her to heal Transformers. Her key can also detect Cybertronians. She is an intelligent girl, with a mischievous streak, but she also has a kind heart. She cares about her father, who works really hard. Though like most eight-year-olds, she has a fit when things don't go her way, and freaked out at the first sight of Autobots.

In an extended opening sequence, Sari is shown driving a bike which she uses her key to transform into a flight pack; however it does not make an appearance in the series. In the third season episode "Human Error Part 1" a similar pack turns out to be a Christmas present from her father.

Sari Sumdac has not been a contender in any CBUB matches.
