Avior
Avior was released together with Lumagrowl, Dharak, Snapzoid, Coredem, Phosphos, Strikeflier, and Helix Dragonoid.
Like Helix Dragonoid, Lumagrowl, Coredem, Dharak, and Phosphos, Avior can combine with an array of Bakugan Battle Gear. When opened, Avior's tail can be pushed down, causing its wings to drop down and its head and neck to extend into a more forward position. It is in the BakuExo-Skin series. It is also notable for being one of the few Core Bakugan that includes instructions.

Coredem
Coredem usually has green eyes. It has a jewel in the middle of it's
chest which is the same color of Coredem's eyes. It will be the Guardian Bakugan of Jake in Bakugan: Gundalian Invaders. His
main Bakugan Battle Gear which he will use in
the anime is Rock Hammer. He is the only digitally cloned
Bakugan that is in set K.

Snapzoid
Snapzoid was released together with Lumagrowl,
Avior, Dharak, Coredem,
Phosphos,
Strikeflier,
and Helix Dragonoid.
When opened, it has a button on the back of its head that, when pressed,
will extend the centipede-like appendage from the bottom of it's head.
It is in the BakuDouble Strike series because of its
button that activates the centipede-like appendage. It is unknown which
Brawler or Gundalian will use it, if any.

Helix Dragonoid
n this form, Helix Dragonoid is humanoid, and looks like a combination
of Cross Dragonoid and Apollonir,
just more red than orange compared to Apollonir. He still carries the Perfect
Core in his chest. Helix Drago has 1 set of wings and a spear head
on its tail. It's unknown if he can become Maxus Helix Dragonoid because
he could already combine with JetKor; however, in the anime, Dan says
that he cannot wait to see all six mechanical Bakugan on Drago, so it is
possible to see him in Maxus form later on. The current strongest Helix
Dragonoid is a Pyrus Helix Dragonoid with 900 Gs.It looks similar to Lumino Dragonoid except he has a tail. In the anime,
unlike Neo Dragonoid and Cross Dragonoid, he cannot spin, but he
can attach to Battle Gear.
Helix Dragonoid first appears after Drago carries the BT system into the atmosphere of New Vestroia, attempting to save the Bakugan that weren't going to have the time to be saved. When the BT system activated, Drago seemingly died, but he actually saw the the perfect core inside of him; Wavern. Wavern told Drago not to give in to death, then vanished. Drago awoke and absorbed all of the Attribute Energies and evolved into Helix Dragonoid. Helix Dragonoid battles Helios MK2 and Twin Destructor. He wins, and Helios MK2 admits that Drago is the Ultimate Bakugan and falls down. Drago then helps Helios stand up, and Helios renounces his evil ways as Spectra reverts into Keith. In episode 45, Drago gets his own Battle Gear, Jetkor, thanks to Keith and Helios's help. He wasn't able to control the Battle Gear at first because his body rejected it.
