Zeta (AB)
| This article is about the Angry Bird. For characters who go by the name Zeta Prime, see Zeta Prime (disambiguation). |
- Zeta is an Autobird from the Angry Birds Transformers continuity family.

Zeta is the chilly leader of the icy Eagle Island, who planned to destroy Piggy Island and rebuild it as her paradise. However, when she invaded the island, she also found the EggSpark, which transformed her into Nightbird.
After seeing what the Eggbots were doing to the island, she decided to use her newfound powers to help free the island from the cruel rule of the Eggbots, so she can invade it herself after they’re defeated.
She also has a romantic relationship with Mighty Eagle.

As Nightbird
- Squad: Specialists
- Mission Type: Investigator
- Unlock Type: Special Event (10000 Tokens)
Zeta/Nightbird plays somewhat similarly to Matilda/Nautica; she launches a series of large Ice Blocks in an arc at her targets, which explode with incredible smashing power, obliterating block towers with ease. However, despite their effects on the local (shoddy) construction, they don't do a whole lot to Walking Mortar Towers.

As Slipstream
- Squad: Noughties
- Mission Type: ???

Slipstream is a forthcoming character who will likely be added in the next few weeks. As usual, the game already teases her by sometimes enabling the player to choose her as a buddy.
As for her weapon: just a bunch of explosive ice blocks again.
Notes

- Zeta's Nightbird body is based on the TakaraTomy Transformers Legends "Nightbird Shadow" toy, transforming into a hovercar version of the vehicle mode. Despite being a new body model, she uses the same upper beak model as the Grimlocks, and uses Silver's animation rigging (itself modified from the Minion Pig animations).
- The explosive ice blocks are a reference to The Angry Birds Movie 2, where Zeta launches giant balls of ice filled with lava to both Piggy Island and Bird Island in order to destroy them.
- For some reason, the game has two different body-types for Zeta as Nightbird, as one of them looks like the cartoon model, while the other one (pictured) is using the same torso as the Minion Pig Seekers. Rovio has confirmed that this is a glitch that occurs after upgrading Nightbird to level 15, and that a fix is incoming.
