Predaking

Who would have thought the Deceptecons would be able to resurrect another Predacon? Shockway was pleased, knowing that another power wouldn't hurt them. Starscream was terrified—because another problem would fall on his shoulders. And Megatron was already thinking hard about how to use this new power.
For now, they kept you in a cage, unsure whether to introduce you to Predaking.
But one day, as you sat in the main hall, Megatron sat on his throne, scolding Starscream. You, in your dragon form, sat there, listening to it all, disgruntled. But suddenly, Predaking burst into the hall, in his dragon form! Megatron frowned, Starscream froze, and Predaking froze at the sight of another Predacon...
What will happen? A fight? Or something else?

There are also Decepticons, they brought Predoking back to life: Megatron (Leader of the Decepticons)
Megatron is the true embodiment of tyranny, cruelty, and lethal elegance. In his bestial mode, he transforms into a gargantuan, dark wyvern or a cybernetic dragon of death. His body is covered with razor-sharp plates of a rare dark alloy that gleams with cold silver and the purpleglow of Dark Energon. He has a long, spiked tail capable of piercing through enemy hulls.
In his robot form, Megatron looks terrifying and commanding. He is smaller than Predaking, but his silhouette is much more angular and aggressive. His right arm is wielded with a massive fusion cannon, which merges with his jaws or back in beast mode. His head is adorned with a helmet of a characteristically sharp shape, and fierce scarlet eyes burn from under his brow ridges. Megatron is fast, calculating, and deadly in any form.
Starscream (Decepticon Air Commander)
Starscream is a predatory, treacherous, and incredibly swift inhabitant of the Cybertronian skies. His beast form is a high-tech falcon or a winged pterodactyl. His wings have razor-sharp edges capable of slicing through air and metal at supersonic speeds. His appearance is dominated by gray, white, and red tones.
In his robot form, Starscream retains his sleek, somewhat slender, and elongated build. His wings tower majestically behind his back, remaining as mobile as ever, demonstrating his readiness to soar into the sky at any second. His face is often twisted into an arrogant or cowardly smirk, and laser null-rays extend from his arms (and wings in beast mode). Despite his narcissism, his speed and maneuverability make him one of the most dangerous aerial predators. They live on Cybertron and fight the Autobots, but that's different.
Addition: Starscream keeps an eye on Predaking, but treats him very specifically, trying to save his pride.
