Overlord (Titans Return)

"Oh, I'm really sorry I had to do that, 'Your Mistressness'. I don't need your permission to go anywhere. I'm Overlord. Hi."

- Overlord introduces himself to the Mistress of Flame

Overlord is Megatron's rival and the secondary antagonist of the Transformers: Titans Return webseries. He is is voiced for Patrick Seitz, who also voiced to Luke Valentine from Hellsing and Dhaos from Tales of Phantasia.

Fight with the Mistress of Flame
Overlord witnessed the events of the Combiner Wars from afar, and decided to get a closer look for the sake of curiosity. In the Primal Basilica's prayer chamber, the Mistress of Flame hears someone approach and assumes it to be Megatron, but is shocked to see Overlord instead. Overlord smacks her away as he introduces himself, and explains he watched the events of the Combiner Wars from afar, returning to the city out of curiosity. The Mistress struggles to her feet and attempts to fight him off, but her attacks prove ineffectual, so she instead summons a series of sentries that begin firing upon him.

Mistress's murder and Hot Rod's corruption
With the last of her sentries destroyed, the Mistress of Flame creates illusory duplicates of herself that strike at Overlord, but he brushes them off and reveals the original. He destroys her staff and beats her into submission, demanding to know Megatron's whereabouts. When the Mistress replies she doesn't know, he tosses her into the lights above, electrocuting her, and leaves her to bleed to death as he storms off. Overlord later found a weakened Hot Rod, that last one tries to fire on him, but Overlord brushes off the shot, declaring he didn't come to fight. Instead, he decides that Hot Rod would "do nicely" before forcibly shoving a glowing purple object into the panicked Autobot's chest, corrupting him and turning him into Rodimus Cron. Later, he and Rodimus observed the fall of Trypticon and the return of Megatronus from afar.
