Lars still ages after his revival, but at an incredibly slow rate; as notated by the incredibly slow beat of his heart that can be heard while in his hair dimension.
Lars is confirmed to have all of the same abilities as Lion after his revival. It is also confirmed the two were brought back through the same means I.E Revival after death.
Lars can only be killed by reaching the maximum extent of his lifespan. Physical damage would only put him into a coma-like state of rest. The creators a quoted saying he will "Outlive everyone he ever cares for." And that he "Will live far longer than he even wants to."
It is frequently suggested that Lars struggles with feeling okay being himself both before and especially after being revived.
About me: Lars Barriga, even as a human he had a noble heart. Albeit one often clouded by his cowardice. That was until the fateful moment when he breathed his last breath, driving a spike through the center of an eye drone seeking to hurt his friends. The explosion, unfortunately, claimed his life immediately after the first action he ever really took that had any meaning. In those precious moments where his life flashed before his eyes he was reminded just how opaque his life had been until then. He thought that at least he'd be remembered for doing one thing right, but somehow... it didn't seem to matter then. All he could see was the face of someone he'd be leaving behind. His eyes had drifted closed and his heart had beat it's last, but just as he had began walking towards the milky white haze that he assumed would be his afterlife; something warm began to fill his being and in an instant he was slowly back to opening his eyes. Steven had managed to bring him back, but what did that mean for him? What was he supposed to do?

Powers and Abilities: (These are confirmed canonical as of the finale of the podcast.)
Concussive Shout/Sonic Boom Generation: Lars has a loud, powerful shout that sends pink rings to knock down/destroy structures. Examples include knocking down multiple sand constructs, pushing the remains of the Gem Warship. Lars' shout isn't as powerful as Lion's roar, but holds many of the same properties. It was also mentioned that he can project what the creators referred to as "Sonic Boom Fingerguns".
Portal Creation and Manipulation: Lars' voice can also open up pink portals, connecting two non-adjacent areas.
Pocket Dimension: Lars' hair also acts similarly to Lion's mane. Retaining an accessible pocket dimension that entire beings can enter or travel through in addition to storing items within.
Supernatural Stamina: Lars has incredible stamina that should be assumed on a similar footing as Lion's. Lion was able to keep pace with Greg's van for nearly an entire day while carrying Steven and Connie on his back. Lars can do roughly half that with his current training and experience.
Water-Walking: Lars, like Lion; can travel atop the surface of water, even leaping or pouncing off of it, showing that the surface acts as a solid to them.
Lars should be expected to display many of Lion's abilities and feats as both are revived by the power of Pink Diamond.

"HIYA! I was told there would be doughnuts!" A clear sparkle in her reptilian eye as she spoke. "My name's Tatsuo, by the way!
