A robotic dog in a digitised city, Luna will aid Red, the protagonist of Transistor, without question. Available as a skill upon defeating the first boss, Luna is eventually named by the Transistor when she is found inside a mysterious backdoor leading to a scenic island retreat. Not unlike K-9 from Fallout 2, Luna is able to move vast distances in a single turn and attack the enemy from behind. Aside from helping directly in combat, Luna can also be added as an upgrade to another skill, adding the chance to most other abilities to prevent enemies from respawning. Outside of combat, the player can frolic on the beach and play with Luna, as it barks and bounces a ball with its master. If that level of adorable isn't worthy of a spot on this, nothing is.
