The Ultimate Good of the Hellaverse.
The Hellaverse is a black comedy musical animated universe created by Vivienne Medrano, better known as VivziePop. The universe consists of the Amazon Prime animated series Hazbin Hotel and the spin-off YouTube web show Helluva Boss. While there are few characters from both Heaven and Hell who come close to being the Ultimate Good, the title ultimately falls, ironically, on the King of Hell himself, Lucifer Morningstar.
Potential Candidates[]
Charlie Morningstar[]

The main protagonist of Hazbin Hotel, Charlie is the daughter of Lucifer and Lilith and founder of the Hazbin Hotel. She is devoted to saving Sinners from the exterminations through rehabilitation and redemption, and was able to fight off the Season 1 Extermination alongside her father and the rest of the Hotel crew. She also managed to prove everyone wrong thanks to Sir Pentious ascending to Heaven, though not even she is aware of that yet.
At the moment, Charlie fails to her father in terms of influence and power, but that is easily able to change in future seasons as a result of her being the protagonists herself; it's been implied numerous times her power is comparable to Lucifer's, but she just holds back.
Lilith Morningstar[]

The Queen of Hell, Lucifer's estranged wife, and Charlie's disappeared mom. Lilith, alongside Lucifer, gave humanity free will through giving Eve the Forbidden Fruit, helping create Hell in the first place. She was also the one that was able to get Hell to prosper, allowing the events of the series to take place, and is ultimately part of why Charlie wants to redeem sinners. While her power has never been stated in the series, outside media places her on a level comparable to Charlie.
While Lilith is currently presented as a good person, this can easily change due to the twist in the Season 1 finale that she's residing in Heaven after an unknown deal with Adam, which could damage her status as the Ultimate Good, or just "good" in general.
Emily[]

One of Heaven's Seraphim, Emily is the one individual in Heaven who believes in Charlie's plan to rehabilitate sinners. She, alongside Charlie, is indirectly responsible for exposing the Exterminations to Heaven in the first place. As a Seraphim, her power should be comparable to that of Lucifer himself.
However, Emily hasn't done enough yet in either influence or admirability to count as the Ultimate Good. That said, she can easily do more in future seasons as her character arc has just started, and it will have to wait until the later seasons when she'll get to do more to change the status quo in Heaven and see if she can qualify as TUG.
Close Contenders[]
Vaggie[]

Charlie's girlfriend. Secretly a fallen angel, despite having slaughtered thousands of sinners through her past, she was able to redeem herself and now actively helps Charlie in redeeming Sinners in their hotel. As an angel, her strength is superior to that of non-Overlord sinners.
However, she ultimately fails in heroism to both Lucifer and Charlie in influence, since she's only the chief helper of the latter. She is also vastly less powerful or influential.
Sir Pentious[]

A former villain, Sir Pentious is a Sinner that Charlie convinces to change for the better and join the Hazbin Hotel. Slowly developing through the first season, he ultimately sacrifices his life in the season finale to slow down Adam, which lets him resurrect in Heaven as the first ever example of a human soul ascending from Hell; which is very admirable and bound to have massive influence over the series.
Despite this, Pentious is massively outdone in power by numerous other characters, as he is pointed out to be a complete wimp physically.
