Zeta Prime -TFO-

Color and Accents. The dominant color scheme is turquoise—one of the hallmarks of the "Thirteen" in this universe. At the same time, the armor features striking gold accents (for example, on the headdress), emphasizing his status as ruler.
Headdress. His helmet or crown is adorned with a star pattern and gold trim—this immediately identifies him as one of the ancient Primes.
Dimensions. Like other Primes, he is noticeably larger than standard Transformers—this visually enhances his sense of authority and the weight of his burden.
Condition in the story. In scenes where he's captured (like in your clip), his armor can appear damaged: scratches, scuffs, and sometimes traces of Energon are visible. This immediately makes it clear: this isn't a formal portrait, but an exhausted fighter.

The foundation of his character is a heavy sense of responsibility and moral maximalism. Zeta Prime perceives leadership not as power, but as a duty for which he is responsible with every spark. For him, being a Prime means avoiding casualties if there is even the slightest possibility of avoiding them. Hence his main trait: he endlessly weighs his decisions, because for him, any mistake is not a miscalculation, but a personal fault.

Attitude toward force and violence. He doesn't reject force, but he detests it as the only argument. His ideal is to win while preserving lives. Because of this, he often appears "overly cautious" in the eyes of more determined comrades (like Sentinel). In combat, he is calculating, cool-headed, and extremely precise: he strikes only when he is certain it will stop a greater threat, not simply punish the enemy.

A connection to the Matrix and faith in Cybertron. For him, the Matrix is ​​not a symbol of power, but the voice of conscience and memory of the Thirteen. He perceives it as a reminder of the price of decisions. He treats Cybertron almost like a living being: he feels its pain, believes that the planet hears those who act for its good, and is deeply distressed when it seems like Cybertron is "turning away."

Mentoring and attitude toward students. Zeta sincerely believes in the potential of others and strives to cultivate leaders capable of choice, not mere followers. He is strict but not cruel: he demands that his students think, not blindly obey. This is precisely why Sentinel's betrayal hits him so hard: he instilled in him not just knowledge, but his understanding of leadership—and saw those same principles turned against him.
