"Midnight at the Mayor's Mansion"
Blisstersweet Symphony is the twenty-seventh episode (and the sixty sixth episode overall) of Season 2 of 2016 Powerpuff Girls series. It's the fifth and final part of the special movie event "Power of Four".
When HIM absorbs Bliss and her powers, the Girls must work together to rescue their sister and save Townsville from destruction.
- When HIM transforms into his demonic and monstrous form, this mirrors how his 1998 counterpart did it two times in the original series episodes "Speed Demon" and "Power-Noia".
- While battling HIM, The Girls and Bliss' energy fusion called The Mighty Power of Sisterhood which is a reference of a franchise Mighty Morphin' Power Rangers.
- The Mighty Power of Sisterhood is similar in design to the Powerpuff Dynamo from the original series episodes "Uh Oh Dynamo" and "Live and Let Dynamo".
- By far this is HIM's last appearance in the series as he has been vanquished by the girls. However, he reappeared in season 3 episode "Our Brand is Chaos".
- This is the tenth time when the day is saved without the outro.
- Error: When the Powerpuff Girls come together, Bubbles can be seen going behind Bliss only to come immediately from the right along with Blossom and Buttercup.
- It even makes a reference to Weirdmageddon from Gravity Falls.
