- Ouroboros, the new character introduced in the Loki season 2 premiere, is the head of the TVA's Repairs and Advancement department and holds crucial knowledge about the TVA.
- Ouroboros's name, referencing the ancient Greek symbol of a snake eating its own tail, suggests a possible future plot point in the MCU related to the cycle of life, death, and rebirth.
- The theme of repetition in the show, represented by Ouroboros - and Loki's own loops in the series - hints at time being a cycle and may have implications for the upcoming multiversal war and a potential MCU reset.
Besides the fact that O.B.’s character is clearly essential to the TVA, the whole meaning behind his character could actually be Loki season 2 hinting at the greater future of the MCU, in the same way Loki season 1 ending unveiled much about the franchise's multiverse. Ouroboros’ name is obviously a reference to the ancient Greek symbol of a snake eating its own tail, often a symbol for the cycle of life, death, and rebirth - which may be a nod to a possible future MCU plot point.
